Move the composition of the default tool services from the Node MCP
server into gods-eye-view/tools/services, a portable export. Given a
fetch that resolves the sources' /api paths, it builds the same services
in a browser as on the local MCP server, so other surfaces can compose
the same catalog. Queries still read only their services.
Mount the local MCP server at /mcp on the development and preview
servers for clients that connect by URL. The route accepts only
requests from this machine that name a loopback host and, when an
Origin is sent, come from a loopback origin, and drains oversized
bodies so the 413 response is delivered. The provider-order regression
test now pins the route between the providers and the API fallback.
Add open_in_gods_eye_view. It builds a version 2 share link looking
straight down on an area, with altitude chosen from the area's size, on
the app address the application supplies.
Add get_traffic_flow over the traffic source's TomTom flow tiles. It
reports average speed as a share of free-flow speed, congested and
closed road length, and a breakdown by road category, stepping down a
zoom level when an area needs more tiles than the source reads at once.
Add vessels_in_area, find_vessel and get_vessel_track over the live
vessel source, and a ships section in situation_brief. Without an AIS
key the source's own message reaches clients as an unavailable feed.
Add get_weather, get_regional_brief, get_cyclones, get_fire_perimeters,
get_terrain_height, find_military_installations and get_map_features
over the application request services and the layers' sources.
situation_brief combines weather, earthquakes, fires, aircraft and
cyclones for an area by reusing those tools, marking sections that are
unavailable instead of failing. get_hud_caption returns the app's
heads-up display caption for the same overview.
Add get_bike_share over the public GBFS systems and get_transit_vehicles
over the GTFS-Realtime feeds. Each finds the systems or feeds whose
coverage reaches the area, reads up to three, and reports any that were
unavailable instead of failing the whole answer. Transit results carry
each feed's attribution and license.
Add search_places and places_nearby over the app's Google Places routes,
and plan_route over its OpenStreetMap routing. The place search service
reports when no search key is configured, so an unconfigured server is
not mistaken for an empty result, and rate limits become retry_later.
Route endpoints accept a place name or coordinates.
Add find_cctv_cameras, get_cctv_snapshot and find_radio_stations. A
snapshot returns the camera's current frame as image content with its
credit. Tool results may now carry base64 images, which the MCP adapter
sends as image content.
Add aircraft_in_area, find_aircraft, get_aircraft_track and
get_aircraft_info over the live aircraft sources, with an optional
military feed, and next_satellite_pass and satellites_overhead over the
satellite catalog and the existing pass predictor.
Source failures from the live contract now become tool errors with the
matching code, so a rate limit reaches clients as retry_later with a
wait time. Tool schemas may use pattern.
Define tools that answer questions from the app's data once, independent
of the surface that exposes them. A tool declares its arguments and the
services it reads; applications compose tools with their own services and
optional call interceptors. Queries reuse the layers' portable source
factories, so they run wherever an application routes /api requests.
The first queries are get_earthquakes, get_active_fires and
get_recent_launches, with a shared area argument (place name, bounding
box, or point and radius) and capped lists.
gods-eye-view/tools/mcp adapts a catalog to the Model Context Protocol
with a small JSON-RPC handler and a stateless HTTP transport, adding no
dependencies. npm run mcp serves Core's tools over stdio to local clients
such as Claude Code, reading from a running app. Both exports are
portable and checked by check:boundaries; the app does not import them.
