The Windows WSL job is the critical path of every CI run (589 to 752 s).
Its checkout sits on the Windows drive, which WSL reaches over 9P, and
writing node_modules there is what makes npm ci take about three minutes
where the Linux job takes 23 s. The step now copies the tree onto the
distro's ext4 filesystem before installing and building, as Microsoft's
WSL guidance recommends for I/O-heavy work.
The e2e job downloaded the full Chromium build (about 165 MB) on every
run, but a headless run with no channel launches chromium-headless-shell
and never opens it. `--only-shell` skips that download.
Every tsconfig now lists the @types packages it uses (node, bun,
vite/client, dom-speech-recognition) instead of relying on TypeScript
auto-including everything under node_modules/@types. On TypeScript 5.9
this is a no-op: identical diagnostics across all 48 projects and
byte-identical emitted .d.ts files. It is a prerequisite for TypeScript 7,
which drops the auto-inclusion; with these lists the Go compiler passes
all 48 projects, so that upgrade becomes a version bump once TypeDoc
supports it.
Two cache-based approaches were evaluated and rejected: an npm cache for
the WSL job (npm ci is slow there because of 9P, not downloads, and a
prefix-restored cache grows without bound) and a Playwright browser cache
(Playwright's docs advise against it; the download is under 10 s).
* feat: Add CesiumJS map server example
A WebGL-based 3D globe example that demonstrates:
- CesiumJS integration with MCP Apps
- CSP configuration for external tile servers
- worker-src directive usage for tile decoding
Tools:
- geocode: Search places via OpenStreetMap Nominatim
- show-map: Display interactive 3D globe at coordinates

* comment out app.registerTool call for now
* prettier
* fix error handling in server-utils.ts
* refactor: rename cesium-map-server to map-server
- Rename examples/cesium-map-server to examples/map-server
- Update package name to @modelcontextprotocol/server-map
- Add README.md with documentation
* style: add min-height of 400px to map container
* feat(map-server): add fullscreen support, clean UI, sharp rendering
- Add fullscreen toggle button (only shown if host supports it)
- Use autoResize: false and manually send height of 400px
- Hide Cesium UI controls (home, scene mode picker)
- Remove location label (gets stale quickly)
- Use full device pixel ratio for sharp rendering on high-DPI displays
- Resize Cesium viewer when display mode changes
* feat(map-server): add reverse geocoding (logging only) and rounded corners
- Add camera move end listener for reverse geocoding
- Debounce Nominatim API calls (1.5s) to respect rate limits
- Log location name to console on camera move
- Add nominatim.openstreetmap.org to CSP connectDomains
- Add 8px rounded corners to map container
* fix(map-server): fix pixelated rendering on high-DPI displays
- Set canvas imageRendering to 'auto' (CesiumJS defaults to pixelated)
- Set resolutionScale to window.devicePixelRatio for native resolution
* tweaks
* update model context w/ current location
* fix(map-server): improve rendering quality and add visible extent logging
Rendering fixes:
- Remove incorrect resolutionScale = devicePixelRatio which was doubling
the scaling factor on Retina displays (2x2=4x), causing blurriness
- Disable FXAA anti-aliasing which can cause blurriness on high-DPI displays
- Keep useBrowserRecommendedResolution: false to use native devicePixelRatio
Reverse geocoding improvements:
- Add getVisibleExtent() using camera.computeViewRectangle() to get the
visible bounding box (west, south, east, north)
- Add getScaleDimensions() to calculate visible area in km
- Add calculateNominatimZoom() to map visible extent to appropriate
Nominatim zoom level (3=country to 18=building)
- Log visible extent with dimensions on each camera move
- Pass zoom parameter to Nominatim for context-aware geocoding results
- Update model context with visible area dimensions
* fix(map-server): direct positioning + wait for tiles before showing
Changes:
- Remove zoom granularity logic from reverse geocoding (was not working)
- Keep extent logging in both console and model context
- Replace flyTo animation with instant setView positioning
- Add waitForTilesLoaded() to detect when tiles finish loading
- Keep loading spinner visible until:
1. Tool input positions camera to destination
2. Tiles at destination are fully loaded
- Add 5-second fallback timeout if no tool input received
- Add 10-second timeout for tile loading to prevent infinite wait
* feat(map-server): use viewbox search to find visible places
Replace center-point reverse geocoding with Nominatim viewbox search:
- Add searchPlacesInBox() that queries Nominatim with bounded viewbox
- Uses layer=address&featuretype=settlement to find cities/towns
- Returns up to 5 visible places in the current view
- Update model context with 'Visible places: City1, City2, ...'
- Still includes center coordinates and extent dimensions
This provides better context about what's actually visible on the map
rather than just the address at the center point.
* fix(map-server): use CARTO @2x retina tiles for sharp rendering
Root cause: Standard OSM tiles are 256x256 pixels. On Retina displays
(devicePixelRatio=2), these get scaled up 2x, making them look pixelated.
Solution: Switch to CARTO Voyager tiles which provide @2x retina support:
- Detect high-DPI displays using window.devicePixelRatio
- Use 512x512 tiles with @2x suffix on Retina displays
- Use 256x256 tiles on standard displays
- Set tileWidth/tileHeight to match actual tile size
- Use CARTO subdomains (a,b,c,d) for load balancing
- Update CSP to allow CARTO tile domains
CARTO Voyager provides clean OSM-based tiles with free @2x retina support,
no API key required.
* fix(map-server): use OSM tiles and fix reverse geocoding
- Switch back from CARTO to standard OSM tiles (tile.openstreetmap.org)
for better detail and label rendering
- Fix geocoding: use reverse geocode API instead of search API
(search API requires a q= parameter, returns 400 without it)
- Update CSP domains for OSM tile server
* fix(map-server): use *.openstreetmap.org wildcard in CSP
Simplify CSP to use wildcard for both tiles and geocoding:
- connectDomains: *.openstreetmap.org covers tile.* and nominatim.*
- resourceDomains: *.openstreetmap.org for tile images
* feat(map-server): multi-point sampling for visible places
- Sample multiple points in visible extent to discover places
- Adaptive sampling based on extent size:
- < 30km: center only (city zoom)
- 30-100km: center + 2 corners
- > 100km: center + 4 quadrants
- Proper rate limiting for Nominatim (1.1s between requests)
- Shows 'Visible places: City1, City2, ...' in model context
- Fix: move geocode tool registration inside createServer()
* format
* fix(map-server): fix Express listen callback + add e2e tests
- Fix incorrect Express listen() callback signature (err param doesn't exist)
- Add map-server to e2e test suite with SLOW_SERVERS timeout (5s for tiles)
- Improve comment about experimental ui/update-model-context API
