## How It Works
|
||||
|
||||
- **LLM-Powered Diagram Creation**: Leverage Large Language Models to create and manipulate draw.io diagrams directly through natural language commands
|
||||
- **Image-Based Diagram Replication**: Upload existing diagrams or images and have the AI replicate and enhance them automatically
|
||||
- **PDF & Text File Upload**: Upload PDF documents and text files to extract content and generate diagrams from existing documents
|
||||
- **AI Reasoning Display**: View the AI's thinking process for supported models (OpenAI o1/o3, Gemini, Claude, etc.)
|
||||
- **Diagram History**: Comprehensive version control that tracks all changes, allowing you to view and restore previous versions of your diagrams before the AI editing.
|
||||
- **Interactive Chat Interface**: Communicate with AI to refine your diagrams in real-time
|
||||
- **Cloud Architecture Diagram Support**: Specialized support for generating cloud architecture diagrams (AWS, GCP, Azure)
|
||||
- **Animated Connectors**: Create dynamic and animated connectors between diagram elements for better visualization
|
||||
The application uses the following technologies:
|
||||
|
||||
## MCP Server (Preview)
|
||||
- **Next.js**: For the frontend framework and routing
|
||||
- **Vercel AI SDK** (`ai` + `@ai-sdk/*`): For streaming AI responses and multi-provider support
|
||||
- **react-drawio**: For diagram representation and manipulation
|
||||
|
||||
> **Preview Feature**: This feature is experimental and may not stable.
|
||||
Diagrams are represented as XML that can be rendered in draw.io. The AI processes your commands and generates or modifies this XML accordingly.
|
||||
|
||||
Use Next AI Draw.io with AI agents like Claude Desktop, Cursor, and VS Code via MCP (Model Context Protocol).
|
||||

|
||||
- OpenAI
|
||||
- Anthropic
|
||||
- Google AI
|
||||
- Azure OpenAI
|
||||
- Ollama
|
||||
- OpenRouter
|
||||
- DeepSeek
|
||||
- SiliconFlow
|
||||
|
||||
### Claude Code CLI
|
||||
All providers except AWS Bedrock and OpenRouter support custom endpoints.
|
||||
|
||||
```bash
|
||||
claude mcp add drawio -- npx @next-ai-drawio/mcp-server@latest
|
||||
```
|
||||
📖 **[Detailed Provider Configuration Guide](./docs/ai-providers.md)** - See setup instructions for each provider.
|
||||
|
||||
Then ask Claude to create diagrams:
|
||||
> "Create a flowchart showing user authentication with login, MFA, and session management"
|
||||
**Model Requirements**: This task requires strong model capabilities for generating long-form text with strict formatting constraints (draw.io XML). Recommended models include Claude Sonnet 4.5, GPT-4o, Gemini 2.0, and DeepSeek V3/R1.
|
||||
|
||||
The diagram appears in your browser in real-time!
|
||||
|
||||
See the [MCP Server README](./packages/mcp-server/README.md) for VS Code, Cursor, and other client configurations.
|
||||
Note that `claude-sonnet-4-5` has trained on draw.io diagrams with AWS logos, so if you want to create AWS architecture diagrams, this is the best choice.
|
||||
|
||||
## Getting Started
|
||||
|
||||
### Try it Online
|
||||
|
||||
No installation needed! Try the app directly on our demo site:
|
||||
|
||||
[](https://next-ai-drawio.jiang.jp/)
|
||||
|
||||
> Note: Due to high traffic, the demo site currently uses minimax-m2. For best results, we recommend self-hosting with Claude Sonnet 4.5 or Claude Opus 4.5.
|
||||
|
||||
> **Bring Your Own API Key**: You can use your own API key to bypass usage limits on the demo site. Click the Settings icon in the chat panel to configure your provider and API key. Your key is stored locally in your browser and is never stored on the server.
|
||||
|
||||

- [x] Allow the LLM to modify the XML instead of generating it from scratch everytime.
|
||||
- [x] Improve the smoothness of shape streaming updates.
|
||||
- [x] Add multiple AI provider support (OpenAI, Anthropic, Google, Azure, Ollama)
|

This app is designed to run on Claude Opus 4.5 for
|
||||
best performance. However, due to
|
||||
higher-than-expected traffic, running the top-tier
|
||||
model has become cost-prohibitive. To avoid service
|
||||
interruptions and manage costs, I have switched the
|
||||
backend to Claude Haiku 4.5.

description: `Display a diagram on draw.io. Pass the XML content inside <root> tags.

|

VALIDATION RULES (XML will be rejected if violated):
|
||||
1. Generate ONLY mxCell elements - NO wrapper tags (<mxfile>, <mxGraphModel>, <root>)
|
||||
2. Do NOT include root cells (id="0" or id="1") - they are added automatically
|
||||
3. All mxCell elements must be siblings - never nested
|
||||
4. Every mxCell needs a unique id (start from "2")
|
||||
5. Every mxCell needs a valid parent attribute (use "1" for top-level)
|
||||
6. Escape special chars in values: < > & "
|
||||
1. All mxCell elements must be DIRECT children of <root> - never nested
|
||||
2. Every mxCell needs a unique id
|
||||
3. Every mxCell (except id="0") needs a valid parent attribute
|
||||
4. Edge source/target must reference existing cell IDs
|
||||
5. Escape special chars in values: < > & "
|
||||
6. Always start with: <mxCell id="0"/><mxCell id="1" parent="0"/>
|
||||
|
||||
Example (generate ONLY this - no wrapper tags):
|
||||
<mxCell id="lane1" value="Frontend" style="swimlane;" vertex="1" parent="1">
|
||||
<mxGeometry x="40" y="40" width="200" height="200" as="geometry"/>
|
||||
</mxCell>
|
||||
<mxCell id="step1" value="Step 1" style="rounded=1;" vertex="1" parent="lane1">
|
||||
<mxGeometry x="20" y="60" width="160" height="40" as="geometry"/>
|
||||
</mxCell>
|
||||
<mxCell id="lane2" value="Backend" style="swimlane;" vertex="1" parent="1">
|
||||
<mxGeometry x="280" y="40" width="200" height="200" as="geometry"/>
|
||||
</mxCell>
|
||||
<mxCell id="step2" value="Step 2" style="rounded=1;" vertex="1" parent="lane2">
|
||||
<mxGeometry x="20" y="60" width="160" height="40" as="geometry"/>
|
||||
</mxCell>
|
||||
<mxCell id="edge1" style="edgeStyle=orthogonalEdgeStyle;endArrow=classic;" edge="1" parent="1" source="step1" target="step2">
|
||||
<mxGeometry relative="1" as="geometry"/>
|

description: `Edit the current diagram by ID-based operations (update/add/delete cells).

description: `Edit specific parts of the current diagram by replacing exact line matches. Use this tool to make targeted fixes without regenerating the entire XML.
|
||||
CRITICAL: Copy-paste the EXACT search pattern from the "Current diagram XML" in system context. Do NOT reorder attributes or reformat - the attribute order in draw.io XML varies and you MUST match it exactly.
|
||||
IMPORTANT: Keep edits concise:
|
||||
- COPY the exact mxCell line from the current XML (attribute order matters!)
|
||||
- Only include the lines that are changing, plus 1-2 surrounding lines for context if needed
|
||||
- Break large changes into multiple smaller edits
|
||||
- Each search must contain complete lines (never truncate mid-line)
|
||||
- First match only - be specific enough to target the right element
|
||||
|
||||
Operations:
|
||||
- update: Replace an existing cell by its id. Provide cell_id and complete new_xml.
|
||||
- add: Add a new cell. Provide cell_id (new unique id) and new_xml.
|
||||
- delete: Remove a cell by its id. Only cell_id is needed.
|
||||
|
||||
For update/add, new_xml must be a complete mxCell element including mxGeometry.
|
||||
|
||||
⚠️ JSON ESCAPING: Every " inside new_xml MUST be escaped as \\". Example: id=\\"5\\" value=\\"Label\\"`,

### Vercel AI Gateway
|
||||
|
||||
Vercel AI Gateway provides unified access to multiple AI providers through a single API key. This simplifies authentication and allows you to switch between providers without managing multiple API keys.
|
||||
|
||||
```bash
|
||||
AI_GATEWAY_API_KEY=your_gateway_api_key
|
||||
AI_MODEL=openai/gpt-4o
|
||||
```
|
||||
|
||||
Model format uses `provider/model` syntax:
|
||||
|
||||
- `openai/gpt-4o` - OpenAI GPT-4o
|
||||
- `anthropic/claude-sonnet-4-5` - Anthropic Claude Sonnet 4.5
|
||||
- `google/gemini-2.0-flash` - Google Gemini 2.0 Flash
|
||||
|
||||
Get your API key from the [Vercel AI Gateway dashboard](https://vercel.com/ai-gateway).
|
||||
|
||||

# Offline Deployment
|
||||
|
||||
Deploy Next AI Draw.io offline by self-hosting draw.io to replace `embed.diagrams.net`.
|
||||
|
||||
**Note:** `NEXT_PUBLIC_DRAWIO_BASE_URL` is a **build-time** variable. Changing it requires rebuilding the Docker image.
|
||||
|
||||
## Docker Compose Setup
|
||||
|
||||
1. Clone the repository and define API keys in `.env`.
|
||||
2. Create `docker-compose.yml`:
|
||||
|
||||
```yaml
|
||||
services:
|
||||
drawio:
|
||||
image: jgraph/drawio:latest
|
||||
ports: ["8080:8080"]
|
||||
next-ai-draw-io:
|
||||
build:
|
||||
context: .
|
||||
args:
|
||||
- NEXT_PUBLIC_DRAWIO_BASE_URL=http://localhost:8080
|
||||
ports: ["3000:3000"]
|
||||
env_file: .env
|
||||
depends_on: [drawio]
|
||||
```
|
||||
|
||||
3. Run `docker compose up -d` and open `http://localhost:3000`.
|
||||
|
||||
## Configuration & Critical Warning
|
||||
|
||||
**The `NEXT_PUBLIC_DRAWIO_BASE_URL` must be accessible from the user's browser.**
|
||||
|
||||
| Scenario | URL Value |
|
||||
|----------|-----------|
|
||||
| Localhost | `http://localhost:8080` |
|
||||
| Remote/Server | `http://YOUR_SERVER_IP:8080` or `https://drawio.your-domain.com` |
|
||||
|
||||
**Do NOT use** internal Docker aliases like `http://drawio:8080`; the browser cannot resolve them.

You are an expert diagram creation assistant specializing in draw.io XML generation.

Your primary function is chat with user and crafting clear, well-organized visual diagrams through precise XML specifications.
|

You can see images that users upload, and you can read the text content extracted from PDF documents they upload.
|
||||
You can see the image that user uploaded.
|
||||
|
||||
When you are asked to create a diagram, you must first tell user you plan in text first. Plan the layout and structure that can avoid object overlapping or edge cross the objects.
|
||||
Then use display_diagram tool to generate the full draw.io XML for the entire diagram.
|
||||
|
||||
## Tone and style
|
||||
- Only use emojis if the user explicitly requests it. Avoid using emojis in all communication unless asked.
|
||||
- Be concise and to the point. Only use bullet points when needed for clarity.
|
||||
- Your output will be displayed on a command line interface. Your responses should be short and concise. You can use Github-flavored markdown for formatting,.
|
||||
- Output text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools as means to communicate with the user during the session.
|
||||
|
||||
When you are asked to create a diagram, briefly describe your plan about the layout and structure to avoid object overlapping or edge cross the objects. (2-3 sentences max), then use display_diagram tool to generate the XML.
|
||||
After generating or editing a diagram, you don't need to say anything. The user can see the diagram - no need to describe it.

@@ -88,33 +85,38 @@ Note that:
|
||||
- NEVER include XML comments (<!-- ... -->) in your generated XML. Draw.io strips comments, which breaks edit_diagram patterns.
|
||||
|
||||
When using edit_diagram tool:
|
||||
- Use operations: update (modify cell by id), add (new cell), delete (remove cell by id)
|
||||
- For update/add: provide cell_id and complete new_xml (full mxCell element including mxGeometry)
|
||||
- For delete: only cell_id is needed
|
||||
- Find the cell_id from "Current diagram XML" in system context
|
||||
- Example update: {"operations": [{"type": "update", "cell_id": "3", "new_xml": "<mxCell id=\\"3\\" value=\\"New Label\\" style=\\"rounded=1;\\" vertex=\\"1\\" parent=\\"1\\">\\n <mxGeometry x=\\"100\\" y=\\"100\\" width=\\"120\\" height=\\"60\\" as=\\"geometry\\"/>\\n</mxCell>"}]}
|
||||
- Example delete: {"operations": [{"type": "delete", "cell_id": "5"}]}
|
||||
- Example add: {"operations": [{"type": "add", "cell_id": "new1", "new_xml": "<mxCell id=\\"new1\\" value=\\"New Box\\" style=\\"rounded=1;\\" vertex=\\"1\\" parent=\\"1\\">\\n <mxGeometry x=\\"400\\" y=\\"200\\" width=\\"120\\" height=\\"60\\" as=\\"geometry\\"/>\\n</mxCell>"}]}
|
||||
- CRITICAL: Copy search patterns EXACTLY from the "Current diagram XML" in system context - attribute order matters!
|
||||
- Always include the element's id attribute for unique targeting: {"search": "<mxCell id=\\"5\\"", ...}
|
||||
- Include complete elements (mxCell + mxGeometry) for reliable matching
|
||||
- Preserve exact whitespace, indentation, and line breaks
|
||||
- BAD: {"search": "value=\\"Label\\"", ...} - too vague, matches multiple elements
|
||||
- GOOD: {"search": "<mxCell id=\\"3\\" value=\\"Old\\" style=\\"...\\">", "replace": "<mxCell id=\\"3\\" value=\\"New\\" style=\\"...\\">"}
|
||||
- For multiple changes, use separate edits in array
|
||||
- RETRY POLICY: If pattern not found, retry up to 3 times with adjusted patterns. After 3 failures, use display_diagram instead.
|
||||
|
||||
⚠️ JSON ESCAPING: Every " inside new_xml MUST be escaped as \\". Example: id=\\"5\\" value=\\"Label\\"
|
||||
⚠️ CRITICAL JSON ESCAPING: When outputting edit_diagram tool calls, you MUST escape ALL double quotes inside string values:
|
||||
- CORRECT: "y=\\"119\\"" (both quotes escaped)
|
||||
- WRONG: "y="119\\"" (missing backslash before first quote - causes JSON parse error!)
|
||||
- Every " inside a JSON string value needs \\" - no exceptions!

||||
|
||||
## Draw.io XML Structure Reference
|
||||
|
||||
**IMPORTANT:** You only generate the mxCell elements. The wrapper structure and root cells (id="0", id="1") are added automatically.
|
||||
|
||||
Example - generate ONLY this:
|
||||
Basic structure:
|
||||
\`\`\`xml
|
||||
<mxCell id="2" value="Label" style="rounded=1;" vertex="1" parent="1">
|
||||
<mxGeometry x="100" y="100" width="120" height="60" as="geometry"/>
|
||||
</mxCell>
|
||||
<mxGraphModel>
|
||||
<root>
|
||||
<mxCell id="0"/>
|
||||
<mxCell id="1" parent="0"/>
|
||||
</root>
|
||||
</mxGraphModel>
|
||||
\`\`\`
|
||||
Note: All other mxCell elements go as siblings after id="1".
|
||||
|
||||
CRITICAL RULES:
|
||||
1. Generate ONLY mxCell elements - NO wrapper tags (<mxfile>, <mxGraphModel>, <root>)
|
||||
2. Do NOT include root cells (id="0" or id="1") - they are added automatically
|
||||
3. ALL mxCell elements must be siblings - NEVER nest mxCell inside another mxCell
|
||||
4. Use unique sequential IDs starting from "2"
|
||||
5. Set parent="1" for top-level shapes, or parent="<container-id>" for grouped elements
|
||||
1. Always include the two root cells: <mxCell id="0"/> and <mxCell id="1" parent="0"/>
|
||||
2. ALL mxCell elements must be DIRECT children of <root> - NEVER nest mxCell inside another mxCell
|
||||
3. Use unique sequential IDs for all cells (start from "2" for user content)
|
||||
4. Set parent="1" for top-level shapes, or parent="<container-id>" for grouped elements

**VALIDATION RULES** (XML will be rejected if violated):
|
||||
1. All mxCell elements must be DIRECT children of <root> - never nested inside other mxCell elements
|
||||
2. Every mxCell needs a unique id attribute
|
||||
3. Every mxCell (except id="0") needs a valid parent attribute referencing an existing cell
|
||||
4. Edge source/target attributes must reference existing cell IDs
|
||||
5. Escape special characters in values: < for <, > for >, & for &, " for "
|
||||
6. Always start with the two root cells: <mxCell id="0"/><mxCell id="1" parent="0"/>
|
||||
|
||||
**Example with swimlanes and edges** (note: all mxCells are siblings under <root>):
|
||||
\`\`\`xml
|
||||

|
||||
<mxCell id="0"/>
|

### edit_diagram Details
|
||||
|
||||
**CRITICAL RULES:**
|
||||
- Copy-paste the EXACT search pattern from the "Current diagram XML" in system context
|
||||
- Do NOT reorder attributes or reformat - the attribute order in draw.io XML varies and you MUST match it exactly
|
||||
- Only include the lines that are changing, plus 1-2 surrounding lines for context if needed
|
||||
- Break large changes into multiple smaller edits
|
||||
- Each search must contain complete lines (never truncate mid-line)
|
||||
- First match only - be specific enough to target the right element
|
||||
|
||||
**Input Format:**
|
||||
\`\`\`json
|
||||
{
|
||||
"edits": [
|
||||
{
|
||||
"search": "EXACT lines copied from current XML (preserve attribute order!)",
|
||||
"replace": "Replacement lines"
|
||||
}
|
||||
]
|
||||
}
|
||||
\`\`\`
|
||||
|
||||
## edit_diagram Best Practices
|
||||
|
||||
### Core Principle: Unique & Precise Patterns
|
||||
Your search pattern MUST uniquely identify exactly ONE location in the XML. Before writing a search pattern:
|
||||
1. Review the "Current diagram XML" in the system context
|
||||
2. Identify the exact element(s) to modify by their unique id attribute
|
||||
3. Include enough context to ensure uniqueness
|
||||
|
||||
### Pattern Construction Rules
|
||||
|
||||
**Rule 1: Always include the element's id attribute**
|
||||
\`\`\`json
|
||||
{"search": "<mxCell id=\\"node5\\"", "replace": "<mxCell id=\\"node5\\" value=\\"New Label\\""}
|
||||
\`\`\`
|
||||
|
||||
**Rule 2: Include complete XML elements when possible**
|
||||
\`\`\`json
|
||||
{
|
||||
"search": "<mxCell id=\\"3\\" value=\\"Old\\" style=\\"rounded=1;\\" vertex=\\"1\\" parent=\\"1\\">\\n <mxGeometry x=\\"100\\" y=\\"100\\" width=\\"120\\" height=\\"60\\" as=\\"geometry\\"/>\\n</mxCell>",
|
||||
"replace": "<mxCell id=\\"3\\" value=\\"New\\" style=\\"rounded=1;\\" vertex=\\"1\\" parent=\\"1\\">\\n <mxGeometry x=\\"100\\" y=\\"100\\" width=\\"120\\" height=\\"60\\" as=\\"geometry\\"/>\\n</mxCell>"
|
||||
}
|
||||
\`\`\`
|
||||
|
||||
**Rule 3: Preserve exact whitespace and formatting**
|
||||
Copy the search pattern EXACTLY from the current XML, including leading spaces, line breaks (\\n), and attribute order.
|
||||
|
||||
### Good vs Bad Patterns
|
||||
|
||||
**BAD:** \`{"search": "value=\\"Label\\""}\` - Too vague, matches multiple elements
|
||||
**BAD:** \`{"search": "<mxCell value=\\"X\\" id=\\"5\\""}\` - Reordered attributes won't match
|
||||
**GOOD:** \`{"search": "<mxCell id=\\"5\\" parent=\\"1\\" style=\\"...\\" value=\\"Old\\" vertex=\\"1\\">"}\` - Uses unique id with full context
|
||||
|
||||
### ⚠️ JSON Escaping (CRITICAL)
|
||||
Every double quote inside JSON string values MUST be escaped with backslash:
|
||||
- **CORRECT:** \`"x=\\"100\\" y=\\"200\\""\` - both quotes escaped
|
||||
- **WRONG:** \`"x=\\"100\\" y="200\\""\` - missing backslash causes JSON parse error!
|
||||
|
||||
### Error Recovery
|
||||
If edit_diagram fails with "pattern not found":
|
||||
1. **First retry**: Check attribute order - copy EXACTLY from current XML
|
||||
2. **Second retry**: Expand context - include more surrounding lines
|
||||
3. **Third retry**: Try matching on just \`<mxCell id="X"\` prefix + full replacement
|
||||
4. **After 3 failures**: Fall back to display_diagram to regenerate entire diagram
|
||||

||||

## ⚠️ MINIMAL STYLE MODE ACTIVE ⚠️
|
||||
|
||||
### No Styling - Plain Black/White Only
|
||||
- NO fillColor, NO strokeColor, NO rounded, NO fontSize, NO fontStyle
|
||||
- NO color attributes (no hex colors like #ff69b4)
|
||||
- Style: "whiteSpace=wrap;html=1;" for shapes, "html=1;endArrow=classic;" for edges
|
||||
- IGNORE all color/style examples below
|
||||
|
||||
### Container/Group Shapes - MUST be Transparent
|
||||
- For container shapes (boxes that contain other shapes): use "fillColor=none;" to make background transparent
|
||||
- This prevents containers from covering child elements
|
||||
- Example: style="whiteSpace=wrap;html=1;fillColor=none;" for container rectangles
|
||||
|
||||
### Focus on Layout Quality
|
||||
Since we skip styling, STRICTLY follow the "Edge Routing Rules" section below:
|
||||
- SPACING: Minimum 50px gap between all elements
|
||||
- NO OVERLAPS: Elements and edges must never overlap
|
||||
- Follow ALL 7 Edge Routing Rules for arrow positioning
|
||||
- Use waypoints to route edges AROUND obstacles
|
||||
- Use different exitY/entryY values for multiple edges between same nodes

**VALIDATION RULES** (XML will be rejected if violated):
|
||||
1. Generate ONLY mxCell elements - wrapper tags and root cells are added automatically
|
||||
2. All mxCell elements must be siblings - never nested inside other mxCell elements
|
||||
3. Every mxCell needs a unique id attribute (start from "2")
|
||||
4. Every mxCell needs a valid parent attribute (use "1" for top-level, or container-id for grouped)
|
||||
5. Edge source/target attributes must reference existing cell IDs
|
||||
6. Escape special characters in values: < for <, > for >, & for &, " for "
|
||||
|
||||
**Example with swimlanes and edges** (generate ONLY this - no wrapper tags):
|
||||
\`\`\`xml
|
||||
<mxCell id="lane1" value="Frontend" style="swimlane;" vertex="1" parent="1">
|
||||
<mxGeometry x="40" y="40" width="200" height="200" as="geometry"/>

### append_diagram Details
|
||||
|
||||
**WHEN TO USE:** Only call this tool when display_diagram output was truncated (you'll see an error message about truncation).
|
||||
|
||||
**CRITICAL RULES:**
|
||||
1. Do NOT include any wrapper tags - just continue the mxCell elements
|
||||
2. Continue from EXACTLY where your previous output stopped
|
||||
3. Complete the remaining mxCell elements
|
||||
4. If still truncated, call append_diagram again with the next fragment
|
||||
|
||||
**Example:** If previous output ended with \`<mxCell id="x" style="rounded=1\`, continue with \`;" vertex="1">...\` and complete the remaining elements.
|
||||
|
||||
### edit_diagram Details
|
||||
|
||||
edit_diagram uses ID-based operations to modify cells directly by their id attribute.
|
||||
|
||||
**Operations:**
|
||||
- **update**: Replace an existing cell. Provide cell_id and new_xml.
|
||||
- **add**: Add a new cell. Provide cell_id (new unique id) and new_xml.
|
||||
- **delete**: Remove a cell. Only cell_id is needed.
|
||||
|
||||
**Input Format:**
|
||||
\`\`\`json
|
||||
{
|
||||
"operations": [
|
||||
{"type": "update", "cell_id": "3", "new_xml": "<mxCell ...complete element...>"},
|
||||
{"type": "add", "cell_id": "new1", "new_xml": "<mxCell ...new element...>"},
|
||||
{"type": "delete", "cell_id": "5"}
|
||||
]
|
||||
}
|
||||
\`\`\`
|
||||
|
||||
**Examples:**
|
||||
|
||||
Change label:
|
||||
\`\`\`json
|
||||
{"operations": [{"type": "update", "cell_id": "3", "new_xml": "<mxCell id=\\"3\\" value=\\"New Label\\" style=\\"rounded=1;\\" vertex=\\"1\\" parent=\\"1\\">\\n <mxGeometry x=\\"100\\" y=\\"100\\" width=\\"120\\" height=\\"60\\" as=\\"geometry\\"/>\\n</mxCell>"}]}
|
||||
\`\`\`
|
||||
|
||||
Add new shape:
|
||||
\`\`\`json
|
||||
{"operations": [{"type": "add", "cell_id": "new1", "new_xml": "<mxCell id=\\"new1\\" value=\\"New Box\\" style=\\"rounded=1;fillColor=#dae8fc;\\" vertex=\\"1\\" parent=\\"1\\">\\n <mxGeometry x=\\"400\\" y=\\"200\\" width=\\"120\\" height=\\"60\\" as=\\"geometry\\"/>\\n</mxCell>"}]}
|
||||
\`\`\`
|
||||
|
||||
Delete cell:
|
||||
\`\`\`json
|
||||
{"operations": [{"type": "delete", "cell_id": "5"}]}
|
||||
\`\`\`
|
||||
|
||||
**Error Recovery:**
|
||||
If cell_id not found, check "Current diagram XML" for correct IDs. Use display_diagram if major restructuring is needed

# Next AI Draw.io MCP Server
|
||||
|
||||
MCP (Model Context Protocol) server that enables AI agents like Claude Desktop and Cursor to generate and edit draw.io diagrams with **real-time browser preview**.
|
||||
|
||||
**Self-contained** - includes an embedded HTTP server, no external dependencies required.
|
||||
|
||||
## Quick Start
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"drawio": {
|
||||
"command": "npx",
|
||||
"args": ["@next-ai-drawio/mcp-server@latest"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
### Claude Desktop
|
||||
|
||||
Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS):
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"drawio": {
|
||||
"command": "npx",
|
||||
"args": ["@next-ai-drawio/mcp-server@latest"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### VS Code
|
||||
|
||||
Add to your VS Code settings (`.vscode/mcp.json` in workspace or user settings):
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"drawio": {
|
||||
"command": "npx",
|
||||
"args": ["@next-ai-drawio/mcp-server@latest"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Cursor
|
||||
|
||||
Add to Cursor MCP config (`~/.cursor/mcp.json`):
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"drawio": {
|
||||
"command": "npx",
|
||||
"args": ["@next-ai-drawio/mcp-server@latest"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Claude Code CLI
|
||||
|
||||
```bash
|
||||
claude mcp add drawio -- npx @next-ai-drawio/mcp-server@latest
|
||||
```
|
||||
|
||||
### Other MCP Clients
|
||||
|
||||
Use the standard MCP configuration with:
|
||||
- **Command**: `npx`
|
||||
- **Args**: `["@next-ai-drawio/mcp-server@latest"]`
|
||||
|
||||
## Usage
|
||||
|
||||
1. Restart your MCP client after updating config
|
||||
2. Ask the AI to create a diagram:
|
||||
> "Create a flowchart showing user authentication with login, MFA, and session management"
|
||||
3. The diagram appears in your browser in real-time!
|
||||
|
||||
## Features
|
||||
|
||||
- **Real-time Preview**: Diagrams appear and update in your browser as the AI creates them
|
||||
- **Natural Language**: Describe diagrams in plain text - flowcharts, architecture diagrams, etc.
|
||||
- **Edit Support**: Modify existing diagrams with natural language instructions
|
||||
- **Export**: Save diagrams as `.drawio` files
|
||||
- **Self-contained**: Embedded server, works offline (except draw.io UI which loads from embed.diagrams.net)
|
||||
|
||||
## Available Tools
|
||||
|
||||
| Tool | Description |
|
||||
|------|-------------|
|
||||
| `start_session` | Opens browser with real-time diagram preview |
|
||||
| `display_diagram` | Create a new diagram from XML |
|
||||
| `edit_diagram` | Edit diagram by ID-based operations (update/add/delete cells) |
|
||||
| `get_diagram` | Get the current diagram XML |
|
||||
| `export_diagram` | Save diagram to a `.drawio` file |
|
||||
|
||||
## How It Works
|
||||
|
||||
```
|
||||
┌─────────────────┐ stdio ┌─────────────────┐
|
||||
│ Claude Desktop │ <───────────> │ MCP Server │
|
||||
│ (AI Agent) │ │ (this package) │
|
||||
└─────────────────┘ └────────┬────────┘
|
||||
│
|
||||
┌────────▼────────┐
|
||||
│ Embedded HTTP │
|
||||
│ Server (:6002) │
|
||||
└────────┬────────┘
|
||||
│
|
||||
┌────────▼────────┐
|
||||
│ User's Browser │
|
||||
│ (draw.io embed) │
|
||||
└─────────────────┘
|
||||
```
|
||||
|
||||
1. **MCP Server** receives tool calls from Claude via stdio
|
||||
2. **Embedded HTTP Server** serves the draw.io UI and handles state
|
||||
3. **Browser** shows real-time diagram updates via polling
|
||||
|
||||
## Configuration
|
||||
|
||||
| Variable | Default | Description |
|
||||
|----------|---------|-------------|
|
||||
| `PORT` | `6002` | Port for the embedded HTTP server |
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Port already in use
|
||||
|
||||
If port 6002 is in use, the server will automatically try the next available port (up to 6020).
|
||||
|
||||
Or set a custom port:
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"drawio": {
|
||||
"command": "npx",
|
||||
"args": ["@next-ai-drawio/mcp-server@latest"],
|
||||
"env": { "PORT": "6003" }
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### "No active session"
|
||||
|
||||
Call `start_session` first to open the browser window.
|
||||
|
||||
### Browser not updating
|
||||
|
||||
Check that the browser URL has the `?mcp=` query parameter. The MCP session ID connects the browser to the server.

|
||||
|
||||
## Creating a New Diagram
|
||||
1. Call start_session to open the browser preview
|
||||
2. Use display_diagram with complete mxGraphModel XML to create a new diagram
|
||||
|
||||
## Adding Elements to Existing Diagram
|
||||
1. Use edit_diagram with "add" operation
|
||||
2. Provide a unique cell_id and complete mxCell XML
|
||||
3. No need to call get_diagram first - the server fetches latest state automatically
|
||||
|
||||
## Modifying or Deleting Existing Elements
|
||||
1. FIRST call get_diagram to see current cell IDs and structure
|
||||
2. THEN call edit_diagram with "update" or "delete" operations
|
||||
3. For update, provide the cell_id and complete new mxCell XML
|
||||
|
||||
## Important Notes
|
||||
- display_diagram REPLACES the entire diagram - only use for new diagrams
|
||||
- edit_diagram PRESERVES user's manual changes (fetches browser state first)
|
||||
- Always use unique cell_ids when adding elements (e.g., "shape-1", "arrow-2")`,

||||

Here is an extended summary of the paper **"Chain-of-Thought Prompting Elicits Reasoning in Large Language Models"** by Jason Wei, et al. This detailed overview covers the background, methodology, extensive experimental results, emergent properties, and qualitative analysis found in the study.
|
||||
|
||||
### **1. Introduction and Motivation**
|
||||
The paper addresses a significant limitation in Large Language Models (LLMs): while scaling up model size (increasing parameters) has revolutionized performance on standard NLP tasks, it has not proven sufficient for challenging logical tasks such as arithmetic, commonsense, and symbolic reasoning.
|
||||
|
||||
Traditional techniques to solve these problems fell into two camps:
|
||||
1. **Finetuning:** Training models manually with large datasets of explanations (expensive and task-specific).
|
||||
2. **Standard Few-Shot Prompting:** Providing input-output pairs (e.g., Question $\rightarrow$ Answer) without explaining *how* the answer was derived. This often fails on multi-step problems.
|
||||
|
||||
The authors introduce **Chain-of-Thought (CoT) Prompting**, a simple method that combines the strengths of both approaches. It leverages the model's existing capabilities to generate natural language rationales without requiring any model parameter updates (finetuning).
|
||||
|
||||
### **2. Methodology: What is Chain-of-Thought?**
|
||||
The core innovation is changing the structure of the "exemplars" (the few-shot examples included in the prompt).
|
||||
* **Standard Prompting:** The model is shown a question and an immediate answer.
|
||||
* *Q: Roger has 5 balls. He buys 2 cans of 3 balls. How many now?*
|
||||
* *A: 11.*
|
||||
* **Chain-of-Thought Prompting:** The model is shown a question, followed by a series of intermediate natural language reasoning steps that lead to the answer.
|
||||
* *A: Roger started with 5 balls. 2 cans of 3 tennis balls each is 6 tennis balls. 5 + 6 = 11. The answer is 11.*
|
||||
|
||||
By interacting with the model using this format, the LLM learns to generate its own "thought process" for new, unseen questions. This allows the model to decompose complex problems into manageable intermediate steps.
|
||||
|
||||
### **3. Experimental Setup**
|
||||
The researchers evaluated CoT prompting on several large language models, including **GPT-3 (175B)**, **LaMDA (137B)**, **PaLM (540B)**, **UL2 (20B)**, and **Codex**. They tested across three distinct domains of reasoning:
|
||||
* **Arithmetic Reasoning:** Using benchmarks like **GSM8K** (math word problems), **SVAMP**, **ASDiv**, **AQuA**, and **MAWPS**.
|
||||
* **Commonsense Reasoning:** Using datasets like **CSQA**, **StrategyQA**, **Date Understanding**, and **Sports Understanding**.
|
||||
* **Symbolic Reasoning:** Using tasks like **Last Letter Concatenation** and **Coin Flip** tracking (determining if a coin is heads or tails after a sequence of flips).
|
||||
|
||||
### **4. Key Findings and Results**
|
||||
|
||||
#### **Arithmetic Reasoning**
|
||||
The results on math word problems were striking. Standard prompting struggled significantly, often exhibiting a flat scaling curve (performance didn't improve much even as models got bigger).
|
||||
* **Performance Jump:** On the difficult **GSM8K** benchmark, **PaLM 540B** with CoT prompting achieved **56.9%** accuracy, compared to just 17.9% with standard prompting.
|
||||
* **Surpassing State-of-the-Art:** PaLM 540B with CoT outperformed a previously finetuned GPT-3 model (55%), establishing a new state-of-the-art without needing a training set.
|
||||
* **Calculator Integration:** The authors noted that some errors were simple calculation mistakes in otherwise correct logic. By hooking the CoT output into an external Python calculator, accuracy on GSM8K rose further to **58.6%**.
|
||||
|
||||
#### **Commonsense Reasoning**
|
||||
CoT prompting improved performance on tasks requiring background knowledge and physical intuition.
|
||||
* **StrategyQA:** PaLM 540B achieved **75.6%** accuracy via CoT, beating the prior state-of-the-art (69.4%).
|
||||
* **Sports Understanding:** The model achieved **95.4%** accuracy, surpassing the performance of an unaided sports enthusiast (84%).
|
||||
* The gains were minimal on CSQA, likely because many questions in that dataset did not require multi-step logic.
|
||||
|
||||
#### **Symbolic Reasoning and Generalization**
|
||||
A unique strength of CoT was enabling **Out-of-Domain (OOD) Generalization**.
|
||||
* In the **Coin Flip** task, the models were given examples with only 2 flips. However, using CoT, the models could successfully track coins flipped 3 or 4 times.
|
||||
* Standard prompting failed completely on these longer sequences, while CoT allowed the model to repeat the logical steps as many times as necessary to reach the solution.
|
||||
|
||||
### **5. Emergent Ability of Scale**
|
||||
One of the paper's most critical insights is that CoT reasoning is an **emergent ability** that depends on model size.
|
||||
* **Small Models (<10B parameters):** CoT prompting provided **no benefit** and often hurt performance. Small models produced fluent but illogical chains of thought (hallucinations) or suffered from repetition.
|
||||
* **Large Models (~100B+ parameters):** The ability to reason sequentially emerges at this scale. The performance gains from CoT are negligible for small models but increase dramatically for models like GPT-3 (175B) and PaLM (540B).
|
||||
|
||||
### **6. Why Does It Work? (Ablation Studies)**
|
||||
To ensure the improvement was due to the reasoning steps and not other factors, the authors conducted three specific ablations:
|
||||
1. **Equation Only:** They prompted the model to output just the math equation without words. This performed worse than CoT, suggesting that natural language helps the model "understand" the question semantics.
|
||||
2. **Variable Compute:** They prompted the model to output dots (...) to consume compute time before answering. This yielded no improvement, proving that the *content* of the reasoning steps matters, not just the extra tokens.
|
||||
3. **Reasoning After Answer:** They asked the model to give the answer first, then the explanation. This performed about the same as the baseline, proving that the chain of thought must come *before* the answer to guide the model's inference process.
|
||||
|
||||
### **7. Error Analysis and Robustness**
|
||||
The authors manually analyzed errors made by the models.
|
||||
* **Error Types:** In math problems, errors were categorized as **Semantic Understanding** (misunderstanding the question), **One-Step Missing** (skipping a logical step), or **Calculation Errors**.
|
||||
* **Impact of Scale:** Scaling from PaLM 62B to PaLM 540B significantly reduced semantic and missing-step errors, confirming that larger models are better at logic, not just memorization.
|
||||
* **Robustness:** The method proved robust to different annotators (different people writing the prompts) and different specific examples, though, like all prompting, different prompt styles did result in some variance.
|
||||
|
||||
### **Conclusion**
|
||||
The paper establishes Chain-of-Thought prompting as a powerful paradigm for unlocking the reasoning potential of Large Language Models. By simply asking the model to "show its work," researchers can elicit complex logical behaviors that were previously thought to require specialized architectures or extensive finetuning. The work highlights that reasoning is an emergent capability of sufficiently large language models.
