CI used npx @biomejs/biome@latest, which drifted to 2.5.0 and failed
the format job (deprecated config fields + stricter parsing of existing
files like public/resnet50.svg) on unrelated PRs. Pin to the version
already in package.json so CI matches local and pre-commit runs.
* feat: add file-based admin settings panel at /admin
Settings saved in the panel are written to data/settings.json and
overlaid onto process.env, taking precedence over environment
variables and applying immediately without restart. Enable by setting
ADMIN_PASSWORD; on serverless platforms without persistent disk the
panel degrades to read-only.
* polish: admin panel UI improvements
- Provider logos in credential rows (shared ProviderLogo component,
extracted from model-config-dialog)
- Scroll-spy active state in the sidebar nav
- Green success state in the save bar that clears after a few seconds
- Wider content column (max-w-6xl) for less wasted space on desktop
* polish: admin panel section toggles and reorder
- Move Quota & Rate Limits to the end of the settings page
- Add enable switches to Observability and Quota sections; default off
with fields grayed out, auto-on when any field is already configured
* polish: make section enable switch more visible
Wrap the switch in a labeled pill ('Enabled'/'Disabled') with border
and background so the off state is clearly visible.
* refactor: derive admin registry from PROVIDER_INFO, simplify page state
- Provider options, labels, and base-URL placeholders now come from
PROVIDER_INFO instead of hand-copied lists (fixes SiliconFlow .com/.cn
placeholder drift; panel names now match the model-config dialog)
- Replace free-text subgroup strings + SUBGROUP_PROVIDERS reverse map
with a typed provider field on SettingDef
- Precompute SETTINGS_BY_GROUP and PROVIDER_SUBGROUPS at module level
- Merge justSaved into saveMessage, drop unused mainRef, hoist
fetchSettings out of the component, dedupe savedText logic
- Serialize from SETTINGS_REGISTRY directly; json validators in a map
instead of a hardcoded key check
- Make allowPrivateUrls a function so ALLOW_PRIVATE_URLS edits in the
admin panel apply without restart
* feat: graphical model management in admin panel
Replace the provider credential fields and raw AI_MODELS_CONFIG JSON
textarea with a Models section mirroring the in-app model settings UI:
provider instance list with logos, credential fields per provider type,
model add/remove with suggestions, per-model connectivity test, and a
default-provider star.
On save the server derives everything the runtime needs into
settings.json: credential env vars (with _2 suffixes for multiple
instances of one provider), AI_MODELS_CONFIG, and AI_PROVIDER/AI_MODEL
for the default. Secrets round-trip as masked markers and are never
sent back to the browser. The general settings registry now only
covers non-provider settings (generation, access, features,
observability, quota).
* fix: allow testing unsaved providers in admin panel
The test button previously looked up credentials by providerId in the
saved settings, so testing a newly added (unsaved) provider failed with
'Unknown provider or model'. The test endpoint now accepts the client's
current provider state; newly typed secrets are used as-is and masked
markers are resolved against the stored values, so testing works both
before and after saving.
* fix: merge env AI_MODELS_CONFIG with admin panel providers
Previously, saving in the admin panel wrote a complete AI_MODELS_CONFIG
into settings.json, which (by overlay precedence) replaced any config
from .env or ai-models.json — admins lost their env-configured models.
The panel no longer writes AI_MODELS_CONFIG. Instead its providers are
merged with the env baseline at read time in loadRawServerModelsConfig,
and panel credentials go to ADMIN_-prefixed env vars wired up via
apiKeyEnv/baseUrlEnv so they never shadow standard vars. Env-based
providers now appear read-only in the panel, name clashes are rejected,
and a panel default overrides the env default. data/ is now gitignored.
* fix: block global-credential providers already managed via env
Bedrock, Vertex AI, and Ollama credentials live in fixed env vars with
no apiKeyEnv redirection, so a panel instance of one of these would
silently override the credentials that env-configured models rely on.
The API now rejects saving such a provider when the env config already
uses that type, and the Add Provider dropdown disables it with a
'managed via env' note.
* fix: address admin panel review findings
- Security: test-model no longer resolves a stored secret when the
request's baseUrl/provider differs from the stored entry, closing a
path where a tampered baseUrl could exfiltrate a saved key
- Save failures are now visible: the save bar shows the error in red
(was masked by the persistent 'Unsaved changes' text), and per-field
validation errors from the settings API are surfaced under each field
- The Observability/Quota enable switch is now real: toggling off stages
deletion of the group's saved values, and the toggle no longer snaps
back to Enabled after saving
- Env provider's default star is hidden when a panel provider is the
active default (no more double star)
- Clearing a credential field reverts to the stored value instead of
silently deleting it; an explicit X button removes a stored secret
- Form inputs are disabled during an in-flight save
* refactor(admin): split 1549-line admin page into focused modules
Extract admin-shared.ts (types + fetch helper), setting-field.tsx
(registry-driven fields), and models-section.tsx (provider/model
manager) from page.tsx. Pure mechanical move, no behavior change.
* feat(admin): share credential fields with user dialog and localize panel
Extract ProviderCredentialsFields (display name + per-provider
credential inputs) used by both the user ModelConfigDialog and the
admin Models panel; secret input passed via renderSecret (plaintext
vs masked), test button via footer slot. Add full i18n for the admin
panel across en/zh/ja/zh-Hant, reusing modelConfig.* for shared parts.
* fix(admin): address Copilot review findings
- Reflect built-in defaults for boolean settings (ALLOW_PRIVATE_URLS
defaults on) and allow clearing a saved boolean back to default,
so the SSRF toggle matches actual runtime behavior.
- Harden JSON loading: filter settings values to strings only, and
schema-validate stored ADMIN_PROVIDERS entries, dropping malformed
ones instead of letting them reach runtime code.
- Set beforeunload returnValue so the unsaved-changes prompt shows in
all browsers; reject non-finite numbers in settings validation.
- Fix README/CN/JA docs that claimed the panel auto-generates
AI_MODELS_CONFIG (providers are merged at read time, not written).
- Add unit tests for corrupted-file value filtering and provider
schema validation.
* docs: move admin panel details to dedicated docs/{en,cn,ja}/admin-panel.md
The READMEs now carry a short blurb + link, matching the existing
per-topic docs (docker.md, ai-providers.md, ...). Removes the ~22-line
inline section and the duplicated data/settings.json mentions.
* fix(admin): address follow-up Copilot findings on the prior fixes
- loadAdminProviders now validates against a stored-shape schema where
secrets are plain strings, so a hand-edited ADMIN_PROVIDERS holding an
{isSet} marker is dropped instead of later crashing maskSecret().
- loadSettings guards against array values (typeof [] === 'object'),
which would otherwise overlay numeric keys onto process.env.
- Admin SecretInput uses the bare id so the shared component's
<Label htmlFor> stays associated (only one ProviderDetail mounts).
- Add tests: marker-secret rejection, array-values guard, bedrock
multi-secret round-trip.
Updates the SUGGESTED_MODELS quick-add list in lib/types/model-config.ts

The installed 4.0.64 declared `input: z.unknown()` on BedrockToolUseSchema,
which Zod v4 treats as non-optional. With the
`fine-grained-tool-streaming-2025-05-14` beta enabled in lib/ai-providers.ts,
Bedrock's contentBlockStart event arrives without an `input` field, causing
type validation to fail with "expected nonoptional, received undefined".
4.0.101 fixed this upstream by marking input optional on the streaming
tool-use schema. The semver range `^4.0.1` already permitted this; only the
lockfile needed refreshing.
Closes#859
/api/parse-url accepted any URL the user submitted, fetched it via
@extractus/article-extractor, and returned the body as Markdown. With
ALLOW_PRIVATE_URLS unset (the default after #600) the SSRF guard
short-circuited entirely, so an unauthenticated POST could probe
container ports, read AWS IMDS / GCP metadata, and reach same-VPC
internal services.
- parse-url now always rejects private URLs regardless of
ALLOW_PRIVATE_URLS. The flag's only legitimate use case is local
LLM provider baseUrl overrides (validate-model, chat); article
extraction has no business fetching internal hosts. Local LLM
setups (Ollama, LM Studio, etc.) are unaffected.
- Strip a trailing dot from the hostname before equality checks so
the FQDN form "localhost." (which still resolves to 127.0.0.1) is
caught by the existing string match.
Known follow-ups (not addressed here):
- DNS rebinding: hostnames are matched as strings; a public domain
resolving to 127.0.0.1 (e.g. localtest.me) is not caught.
- HTTP redirects: @extractus/article-extractor uses cross-fetch with
default redirect: "follow" and exposes no hook, so a public URL
302-ing to an internal host still leaks.
PR #840 fixed issue #815 in the Electron main process via
will-prevent-unload + preventDefault. The renderer-side workarounds
introduced by previous fix attempts (#642, #648) are no longer needed
and never had effect for their stated purpose.
Removed:
- configuration={ confirmExit: false } in DrawIoEmbed
confirmExit is not a recognized draw.io config key (zero matches in
jgraph/drawio source). This was always dead code.
- modified=0 / keepmodified=0 URL parameters
Per drawio source (app.min.js:14898), these only suppress the
post-save modified-flag clearing — they do not prevent edits from
setting editor.modified=true. They were ineffective for blocking
beforeunload prompts and actually prevented draw.io from clearing
its modified flag after save.
- canPersist / canPersistChecked state and isIndexedDBUsable() probe
Their only purpose was gating the dead config above. Removing them
also removes a startup delay before the iframe renders.
- handleDrawioAutoSave wrapper
After PR #780 stripped its body, it was a pure passthrough useCallback.
Now passes handleDiagramAutoSave directly to onAutoSave.
- withDB / isClosingError / resetDBPromise / onversionchange / onclose
/ terminated handlers in lib/session-storage.ts and lib/template-storage.ts
PR #648 added these to recover from 'IDBDatabase: connection is closing'
errors that PR #642's first land caused via db.close() on the shared
singleton. That bug was already fixed in c5de1a1 (re-land of #642),
three minutes before PR #648 commits started. The retry handlers
defend against multi-tab / version-change scenarios that cannot occur
in this single-instance Electron app (requestSingleInstanceLock).
template-storage.ts copied the same pattern when introduced by #773.
Verified:
- npx tsc --noEmit passes
- Manual test in dev mode: session save/load works, template create works,
diagram-only persistence works.
The draw.io iframe registers a window.onbeforeunload handler that returns
a non-empty string whenever its internal editor.modified flag is true.
After the user edits text in a shape, that flag is set and never cleared.
Per Electron BrowserWindow docs, returning a non-void value from any
beforeunload handler in the page tree silently cancels the window close
without showing a dialog. This is what caused the X button (and Cmd+Q)
to do nothing for users who had typed in a shape.
Calling event.preventDefault() in will-prevent-unload tells Electron to
ignore the iframe's beforeunload return value and proceed with the close.
The host app already persists diagrams via autosave + visibilitychange,
so the prompt was unnecessary.
Verified by reproducing the bug, applying the fix, and re-testing.
Bumps biome.json $schema from 2.4.4 to 2.4.14 so the repo schema
matches the version the 'Auto Format' workflow installs via
@biomejs/biome@latest. Also applies the one auto-fix the newer
version produces (export ordering in electron/electron.d.ts).
Fixes the spurious 'This PR has formatting issues' CI failure that
was blocking fork PRs unrelated to formatting.
* fix: reduce CPU usage during large XML streaming
Skip Prism syntax highlighting while tool call is streaming — use plain
<pre> during streaming and only run Prism once at completion. Also throttle
scrollIntoView to once per 150ms to avoid layout thrashing.
Profiled with Playwright + CDP: for 200-cell diagrams the longest
browser task dropped from 6.7s to ~450ms and total long-task time
fell from ~10.9s to ~1.1s.
* fix: add trailing edge to scroll throttle
Ensures the chat scrolls to the bottom after streaming ends, even if
the last messages update arrives during the 150ms throttle window.
Remove pinned v29.3.5 tag so the build always clones the latest draw.io.
This adds the Animated GIF export and other new features to the Electron app.
Closes#770
All three POST handlers (/api/state, /api/restore, /api/history-svg)
now use a shared readBody() helper that enforces a 10MB limit and
returns 413 if exceeded, preventing memory exhaustion from oversized
requests.
Bumps @next-ai-drawio/mcp-server to 0.1.19.
The embedded HTTP sidecar was using server.listen(port) without a host
argument, which defaults to 0.0.0.0 (all interfaces). This exposed the
server to the local network. Now explicitly binds to 127.0.0.1.
Also excludes release/ from tsconfig to fix pre-existing TS errors.
Bumps @next-ai-drawio/mcp-server to 0.1.18.
- Fix zoom resetting when dragging items (#775): removed useEffect that
called load() on every autosave-triggered chartXML change, which reset
the viewport. Moved diagram restore logic to onDrawioLoad where it
only fires on remount.
- Fix IndexedDB VersionError: template-storage.ts shared the same DB
name as session-storage.ts but at version 2, causing session storage
to fail with "requested version (1) < existing version (2)". Give
templates their own DB ("next-ai-drawio-templates").
Replace wildcard `Access-Control-Allow-Origin: *` with same-origin check,
preventing external websites from accessing MCP server APIs via cross-origin requests.
The npm audit check was failing due to vulnerabilities in transitive
dependencies (e.g. wrangler), blocking unrelated PRs.

* feat: add custom system message setting for AI personalization
Allow users to enter custom instructions via a textarea in Settings
that get appended to the AI's system prompt. Includes server-side
validation (type check + 5000 char limit), localStorage persistence,
and i18n support for all 4 locales.
* fix: add accessibility htmlFor/id pairing on custom system message textarea
* feat: add Material Design Icons shape library (#685)
Add Google Material Design Icons as a new shape library using Google's
CDN. Includes top 300 most popular icons by usage, and updates system
prompts to guide the AI to call get_shape_library before using any icon
library.
* fix: align get_shape_library guidance for non-cloud icon libraries
* feat: add PNG/SVG export support to MCP server export_diagram tool
Previously export_diagram only supported .drawio XML files. This adds
PNG and SVG export by leveraging the existing browser sync mechanism:
the MCP tool sets an exportFormat flag on the session state, the browser
detects it via polling and triggers an iframe export, then POSTs the
result back as exportData which the tool reads and writes to disk.
* fix: address PR review feedback for export feature
- Validate exportData is a string in POST /api/state
- Update lastUpdated in setExportFormat to prevent session expiry
- Gate export postMessage on isReady to avoid lost messages
- Remove unused fmt variable
- Fix double extension when path has a different supported extension
* fix: resolve high severity npm audit vulnerabilities
Run npm audit fix to update @aws-sdk and @smithy transitive dependencies
that had high severity advisories, which was failing the CI security audit step.
* fix: address second round of PR review feedback
- Add 8s timeout for pendingMcpExport to prevent permanent blocking
- Move export trigger after version update in poll() to export latest diagram
- Return 404 when session not found for exportData POST
- Sync browser state before .drawio export to avoid stale XML
- Handle URL-encoded SVG data URIs in addition to base64
* fix: address third round of PR review feedback
- Sync browser state before PNG/SVG export (not just drawio)
- Add 10MB body size limit on POST /api/state
- Validate export response format matches request to prevent race conditions
* refactor: remove over-engineered defensive code from export feature
Strip unnecessary validation/guards added from Copilot review that
don't make sense for a localhost-only MCP server: body size limit,
type validation, 404 for missing session, lastUpdated refresh,
URL-encoded SVG handling. Also deduplicate requestSync call.
* refactor: keep original drawio export path unchanged
Don't restructure the existing drawio logic - just add png/svg
as a separate branch after it.
* refactor: remove redundant helper functions, inline state access
Remove setExportFormat/getExportData/clearExportData wrappers that
were each called once. Access state fields directly via getState().
* chore: bump mcp-server version to 0.1.16
Support multiple API keys per provider with random selection for load
balancing. When AI_MODELS_CONFIG has multiple apiKeyEnv values for
a provider, requests will randomly select one available key.
- Update schema to accept apiKeyEnv as string or string array
- Add random key selection in resolveApiKey()
- Update validation to check at least one key exists
- Add tests for array format support
* fix: enable image support for Kimi K2.5 model
Kimi K2.5 supports image input but was incorrectly blocked by the
supportsImageInput check that excluded all Kimi models without
"vision" in the name. Updated the condition to only exclude the
older K2 model while allowing K2.5.
* fix: improve Kimi K2.5 image support logic and add tests
- Only block kimi-k2 specifically, not all Kimi models
- Add unit test for kimi-k2.5 image support
This reverts commit e7c29fb410.
The PR introduced an IndexedDB error: 'Failed to execute transaction on IDBDatabase: The database connection is closing.'
* fix(electron): prevent beforeunload prompt by using autosave
- Enable draw.io autosave and handle autosave events to update chartXML
- Clear modified state after autosave to avoid beforeunload prompts
- Disable confirmExit in draw.io configuration
- Set modified=false and keepmodified=false URL parameters
- Fix session save condition to also save when only diagram exists
* fix: persist diagram-only saves and ref typing
* fix: harden persistence checks and export timeout
* feat(electron): bundle draw.io for offline support
- Download draw.io static files during CI build (v29.3.5)
- Detect Electron and use local draw.io files instead of CDN
- Add offline=1 parameter to disable external service calls
- Skip /drawio path from i18n middleware redirect
- Add public/drawio/ to .gitignore (downloaded during build)
This allows the Electron app to work completely offline.
* chore: bump version to 0.4.12-beta.3 for offline test
* fix(electron): ad-hoc sign macOS app for bundled draw.io compatibility
* chore: bump version to 0.4.12-beta.4 for ad-hoc sign test
* fix(electron): disable electron-builder signing to use custom ad-hoc signing
* chore: bump version to 0.4.12-beta.5
* feat(mcp): update UI with project logo and modern dialog styles
- Replace Next.js logo with project favicon-white.svg
- Modernize modal dialogs with backdrop blur, animations, and DM Sans font
- Update button styles to match header design
- Change title to "Next AI Draw.io"
- Rename "Save" to "Download" for clarity
- Bump version to 0.1.15
* chore: remove dead code (unused download helpers and pendingManualSave)
Fixes#633 - browser showing infinite loading spinner when accessing
the MCP server URL without the session parameter.
When users access http://localhost:6002 directly (without ?mcp=xxx),
the page now auto-redirects to the most recent active session instead
of showing "No session" with an infinite loading spinner.
Upgrade wrangler from 4.58.0 to ^4.60.0 to fix the command injection
vulnerability (CWE-78) in the --commit-hash parameter of wrangler pages
deploy command.
Fixes#627
* fix(quota): bypass quota for users with Bedrock credentials
The hasOwnApiKey check only looked for x-ai-api-key header, but Bedrock
users provide AWS credentials via x-aws-access-key-id instead. This
caused Bedrock users with their own credentials to still be subject to
quota limits.
* fix(quota): also bypass quota for Vertex AI users
* style: auto-format with Biome

* fix: allow private URLs by default for reverse proxy setups
Fixes#588 - Users with reverse proxy setups (e.g., Antigravity tools)
were getting "Invalid base URL" errors due to SSRF protection blocking
private/internal URLs.
Changes:
- Add ALLOW_PRIVATE_URLS env var (defaults to true)
- Set to "false" to enable strict SSRF protection if needed
* refactor: extract isPrivateUrl to shared utility

PR #442 accidentally changed showSaveDialog from using the diagram
context to local state, breaking draw.io's native save button (Ctrl+S)
that was fixed in PR #296.
This restores the original behavior by using the context's showSaveDialog
so both draw.io native save and the download button open the same dialog.

edits trigger saves (previously only message changes did)
- Destructure stable sessionManager values to prevent unnecessary
effect re-runs on every render
- Add try-catch wrapper around debounced async save operation
- Make saveSession() return boolean to indicate success/failure
- Verify IndexedDB write succeeded before deleting localStorage data
during migration (prevents data loss if write silently fails)
- Keep localStorage data for retry if migration fails instead of
marking as complete anyway
* refactor(session): extract helpers to reduce code duplication
- Add syncUIWithSession helper to consolidate 4 duplicate UI sync blocks
- Add buildSessionData helper to consolidate 4 duplicate save logic blocks
- Remove unused saveTimeoutRef and its cleanup effect
- Net reduction of ~80 lines of duplicate code
* style(ui): improve history dropdown and delete dialog styling
- Change destructive color from coral to muted rose for refined look
- Make session history panel taller (400px fixed height)
- Fix popover alignment to prevent truncation
- Style delete button with soft red outline instead of solid fill
- Make delete dialog more compact (max-w-sm)
* fix(session): reset refs on new chat and show recent sessions
- Fix cached example diagrams not displaying after creating new session
- Reset previousXML, lastProcessedXmlRef and processedToolCalls when
messages become empty (new chat or session switch)
- Add recent chats section in empty chat state with collapsible examples
- Pass sessions and onSelectSession to ChatMessageDisplay
- Add loadedMessageIdsRef to skip animations on session restore
- Add debug console.log for diagram processing flow
* feat(session): add search bar and improve history UI
- Remove session history dropdown, use main panel instead
- Add search bar to filter history chats by title
- Show minutes (Xm ago) instead of "Just now" for recent sessions
- Scroll to top when switching to new/empty chat
- Remove title truncation limit for better searchability
- Remove debug console.log statements
* refactor: remove redundant code and fix nested button hydration error
- Remove unused 'sessions' from deleteSession dependency array
- Remove unused 'switchedTo' variable and simplify return type
- Remove unused 'restoredMessageIdsRef' (always empty)
- Fix nested button hydration error by using div with role=button
- Simplify handleDeleteSession callback
* fix(session): fix migration bug, improve metadata perf, truncate titles
- Fix migration retry loop when localStorage has empty array
- Use cursor-based iteration for getAllSessionMetadata
- Truncate session titles to 100 chars with ellipsis
* refactor: remove dead code and extract diagram length constant
- Remove unused exports: getAllSessions, createNewSession, updateSessionTitle
- Remove write-only CURRENT_SESSION_KEY and all localStorage calls
- Remove dead messagesEndRef and unused scroll effect
- Extract magic number 300 to MIN_REAL_DIAGRAM_LENGTH constant
- Add isRealDiagram() helper function for semantic clarity
