The /mcp route built its Request without a signal, so a tool kept working
after the client left. The request's signal now aborts when the connection
closes before the answer is sent.
Installation tile results can arrive before the name pack, and the tool
answered with generic names such as "Military area" where a moment later
it would say "Camp Mabry". It now waits up to five seconds for the named
result and says when names are still loading.
Traffic figures for a radius area counted roads anywhere in its bounding
box, and a tile that failed to load silently changed them. Roads are now cut
to the circle, and the flow source reports per request whether any tile
failed so the answer can say its figures are partial.
Bike share and transit read only the three nearest systems, and place
search returns at most five matches within 50 km, while answers read as
complete. Answers now name the systems not searched and say when a place
search limit may have left places out.
get_weather dropped the proxy's stale status and get_active_fires dropped
FIRMS staleness and failed satellite sources, so answers and the HUD caption
read them as current. Both now report them, and the caption context marks
such sections stale or degraded.
Fire perimeters were placed at their average vertex, so a fire enclosing the
whole requested area was missed. Polygons now count when a vertex is inside
the area, an edge crosses it, or the polygon contains it outside any hole.
Brief sections received a named place as its bounding box, so they centered
on the box's middle: Tokyo's aircraft were sorted from a point in the
Pacific. Sections now receive the place name and resolve it like a direct
query, and place lookups are cached briefly so a brief resolves it once.
The HTTP handler read the whole body before checking its size, so a body
without Content-Length could be buffered without bound. It now reads the
stream and stops as soon as the body passes the limit.
Cable searches only tested vertices, so a cable crossing an area with no
vertex inside it was missed. Lines now test each segment against the area's
bounds, across the antimeridian too, and against a radius area's great-circle
distance.
The longitude span divided the angular radius by the center's cosine, which
is too narrow for large radii and near the poles. Areas now use the exact
tangent bound and span every longitude when the circle reaches a pole.
The caption request declared every answered section nominal, so a stale
aircraft snapshot reached the caption as live. Each section now reports
stale or unavailable from its own result, and the provenance envelope is
built with the app's feedProvenanceEnvelope.
get_transit_vehicles returned positions from a feed the proxy served from
its error cache, and hour-old fixes, as current. It now applies the transit
layer's rules: a feed is stale when the proxy says so or the operator has
not answered recently, and fixes older than the vehicle limit are dropped
and counted.
find_aircraft failed whenever either feed failed. It now answers from the
feeds that responded, names the ones that did not, and searches only the
military feed for registrations, the only feed that reports them.
situation_brief, military_awareness and the HUD caption called other tools
directly, so replaced tools and interceptors did not apply to their sections.
Tools now reach each other through the catalog, and interceptors see these
calls with the calling tool as parent. Surfaces become a view over the
composed catalog, so a composite offered on voice keeps sections that voice
does not list.
The installation source keeps one named site per display cell for the map.
Queries now ask for every site and the exact box, and report when the
source returned only part of the mapped sites.
src/tools/surfaces.js lists the tools a surface leaves out, and the MCP
server, the voice session's tool list and the browser catalog voice calls
all filter through it. Voice leaves out tools that answer with images, link
to the app, or repeat what its app actions already answer.
A stalled global snapshot held the request for over a minute. Each attempt
now gets 10 seconds, a timed-out or failed attempt is retried once, and a
second failure is answered from the stale cache or the regional fallback.
The OAuth token request gets the same limit.
Unknown aircraft tracks read as empty instead of a server error, aircraft
info names the aircraft and flight, the HUD caption sends the app's caption
context, and satellite pass, satellites overhead and nearby places take a
place name or point like the other tools.
The datacenter and dam layers parsed their bundled GeoJSON Lines and
built analyst records inside the Cesium-backed layer module. Move the
data URLs, the line parser, mapAnalystRecord and layerTitle unchanged to
src/sources/infrastructureData.js; the layer module imports them and
still exports mapAnalystRecord. The consumer-build pin lists the new
module.
Add find_alpr_cameras over the layer's OpenStreetMap camera extracts:
cameras in a US or Canadian area of at most 3° per side, nearest first,
with operator, manufacturer and facing direction, and the source's
attribution. Areas outside coverage or too wide are reported.
Add find_submarine_cables over the bundled TeleGeography data: cables
passing through or landing in an area, or matching a name, with landing
points and the dataset's attribution. The local MCP server's fetch reads
the bundled data files a browser would load by URL, and nothing outside
that directory.
Add get_recent_imagery. It searches the recent Harmonized Landsat and
Sentinel-2 catalog for an area, picks the image the layer would show
with the layer's own ranking, and returns it with its date, sensor and
cloud cover, falling back to the VIIRS daily overview.
Add get_weather_map, which returns the latest NOAA radar, satellite or
lightning map over an area as an image, choosing a window the image
route accepts and reporting areas outside the product's coverage, and
get_wind, which samples GFS or IFS wind at a location with the wind
layer's own grid sampling.
Add getImage() to the weather source. It reads one frame through the
bounded image route the layer already uses and returns its content type
and bytes, so code outside the layer can show the current map.
open_in_gods_eye_view accepts layers and writes them with the app's own
share-link layer codec, so the link opens with those layers on. Layer
names are limited to the registered layer ids.
layerState.js held both the share-link layer codec and the coordinator
that restores layer choices into the running app and persists them to
browser storage. Move the coordinator, unchanged, to
layerStateCoordinator.js so the codec stays a pure data module that code
outside the browser can use to write share links. The registry stays in
layerState.js, where the token tooling reads it, and the aircraft
barrel re-exports both.
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.
A place's bounds can reach far from the place itself; Tokyo's include
remote Pacific islands, so the middle of its box is open ocean. Keep the
geocoder's point for a named place and use it as the area's center,
while bounds still decide what lies inside the area.
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 getFeeds() to the transit source. It reads the public catalog route
the server already serves, so code outside the layer can find feeds
near a location without loading the layer.
The bike-share layer parsed station documents inside its model factory.
Move the parsers unchanged to src/sources/gbfsStations.js and have the
model import them, so code outside the layer can read GBFS stations
without constructing the layer.
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 getFrame(camera) to the CCTV source. It reads one frame through the
registered frame endpoint the layer already uses and returns its content
type and bytes, so code outside the layer can show a camera's view.
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.
The satellites layer parsed catalog text inside its Cesium-backed orbit
owner. Move the parser unchanged to src/sources/tle.js, add a catalog
number helper, and have the layer delegate to it so code outside the
layer can read TLE text without loading rendering.
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.
Traffic roads come from OpenFreeMap vector tiles, or TomTom flow tiles with a
key (Hybrid by default). Military areas use OpenFreeMap polygons with a bundled
worldwide name index; wide views show named points. ALPR reads an hourly
OpenStreetMap extract. Cockpit place context and country, state and US county
outlines use bundled Natural Earth and US Census data. Overpass is used only
when an operator configures their own endpoint.
Also: camera arrivals no longer land below ground, keyless terrain retries on
429, bounded relation geometry for configured Overpass, one shared
OpenStreetMap credit, and separate tile and API transports for embedders.
