MCP servers that compose Core's tools can now serve the globe panel:
@gods-eye-view/core/tools/panel exports createGlobePanelResource,
panelRuntime, GLOBE_PANEL_URI and PANEL_BASE. The local MCP server uses
the same entry point.
localRequestGate.mjs owns the reverse-proxy header list and hasProxySignals;
Provider Settings, the cross-site gate and /mcp all use it instead of two
copies of the same nine names. The changelog credits the cross-site gate.

Panels on one MCP server share six requests in flight; further requests
wait their turn (up to 256 waiting) instead of failing, and a waiting
request leaves the queue when its caller cancels. Held responses belong to
their own MCP server rather than to the process. /mcp request bodies must
arrive within 30 seconds. Over stdio, a client's notifications/cancelled
aborts the named request, which then gets no response.

The /mcp route now applies the same proxy and sharing checks as Provider
Settings: requests carrying forwarding headers, or arriving while launcher
sharing is on, are refused. The Host must name the port the request reached
and a browser Origin must match that host exactly. The proxy and sharing
checks move into shared helpers in keySetupCore; Provider Settings behaves
as before.

panel_request now requires a key that each MCP server generates and places
in its panel page, which keeps the tool from clients that list it to the
model without loading the panel. The key is not access control: any MCP
client can read the panel page. Routes the panel never loads (provider
settings, credential and model endpoints, the MCP endpoint and development
server internals) are refused to every caller, regardless of letter case or
encoding.

Hosts serve panels from their own sites and may refuse other addresses;
Codex refuses any address on the user's machine. The panel now never
requests the app's server: it loads the app's panel build and data
through panel_request, a tool only the panel may call, which requests
the path from the app's server. One path in every host; only map
providers load directly.
npm run build:panel writes the panel build to dist/panel, served at
/panel/: one app script, one stylesheet, Cesium's script, and Cesium's
workers as one script Cesium runs from memory. Tools may now be marked
app-only. The panel CORS rules are gone.
The stdio server writes each request's method, and the tool or resource it
names, to stderr, which clients such as Claude Desktop copy into their logs.
Arguments and results are never logged.
show_on_globe replaces open_in_gods_eye_view and names an MCP Apps view, a
ui:// panel that loads the app in embed mode and posts each later view to it,
so the globe in the conversation changes without reloading. It also takes a
view another answer returned. Tools can declare a UI resource, and the MCP
adapter serves resources/list and resources/read and lists each tool's
resource in _meta.ui.resourceUri.
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.
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.
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.
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.
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.
