- Remove border-radius and overflow: hidden from cesiumContainer CSS
- Capture map canvas as base64 PNG and include in updateModelContext
- Only include image if host supports image content blocks
* feat(map-server): reduce screenshot size for fewer tokens

- Truly stateless (no session management needed)
- Single server.ts (~350 lines) + main.ts CLI entry point
- Instant startup (no preloading)

Removed files:
- src/pdf-indexer.ts
- src/pdf-loader.ts
- src/types.ts

* 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

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
