The vessel source accepts an optional area and sends it as lat, lon and
radius_km. The vessel layer asks for the area the camera shows (centered
on the middle of the screen, sized by camera height), or every vessel
from high enough up, and asks again when the view moves or zooms by a
quarter of that radius. vessels_in_area names its area too. Servers that
hold every vessel may ignore the area; callers still keep only what is
inside it.
The server routes a mounted path when a dot follows it, so /mcp.json reached
the MCP endpoint while panel_request refused only /mcp and /mcp/...; the same
held for the provider-settings, credential and model routes. The refusals now
match a dot after the route as well. A regression test drives panel_request
against a real Vite server.

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.

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.

Asked for an aircraft's cockpit view, assistants passed only the follow,
which failed for want of an area or camera, so every such request took
a second call. show_in_gods_eye_view now looks the aircraft up and frames
the view on it, and says so when the aircraft is not reported.
A view's follow may ask for cockpit view, which the app enters after it
follows the aircraft; links cannot carry it and open the app following.
Applying a view no longer flies the camera when the followed entity is
already there, since the flight ended the follow; it flies only while
waiting for the entity. The panel applies its first view again only
when it asks for cockpit view.
panel_request resolved paths with a check for a leading //, but URL
parsing also reads /\host as another host, so it could request other
servers. It now resolves the path against the app's address, refuses
any other origin, matches refused routes decoded as well, and does not
follow redirects. Responses are capped at 64 MiB while reading, with a
deadline; held responses make room on arrival and expire by time only,
so a response being read keeps its parts.
The panel keeps converted images only for its build files, so live
camera frames no longer accumulate, and failed build loads are retried.
The dev server answers a malformed /panel/ path with 400 instead of
crashing.
Drop the render restarts added while chasing the black overlays; keep
the full render-error report and stop the timer after an error, as
Cesium does. Correct comments the investigation outran, share the
panel_request name, and document the host differences the panel works
around.
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.
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.
A view can carry the marks the app's annotate_map action draws, and links
carry them in the an parameter, bounded in count and size. A tilted view of
an area now places the camera behind its center so the area stays in the
middle of the frame.
Tool answers with something to show now include data.view: the view with
the matching layers on, the area framed from above or a single aircraft or
satellite followed, and the link that opens it. Area framing moves to
src/tools/views.js so links and answers frame alike.
A view is a camera, data layers, visual style, map imagery and an aircraft,
military aircraft or satellite to follow, written in the share-link format
the app already restores. gods-eye-view/view builds, encodes and decodes one,
and share links take their style names from it. open_in_gods_eye_view now
builds its link from a full view: an area or camera, layers, style, map and
something to follow.
find_aircraft merged the records of the feeds that answered and dropped their
freshness, so a stale OpenSky snapshot read as a current "not reported".
Answers now list each feed with its freshness and coverage and say which
feed's data may be stale.
Vessel tools read the source's default of the newest 12,000 vessels while
the server keeps up to 50,000, so a lookup could miss a vessel still held.
They now ask for more than any server keeps and receive everything it has.
An empty camera answer outside the catalog's regions read as "0 public
cameras", as if the area had none. It now says the catalog has no cameras
there.
Coverage was checked only for packs among the cameras found, so an area
whose cameras were all trimmed away answered zero cameras, complete. The
catalog now reports where each trimmed pack's cameras are, and the tool
marks an answer partial whenever its area overlaps that region.
The map window was moved inside the product's bounds without checking that
it still covered the requested area, so an area across the antimeridian got
an image of only one side. A window must now hold the whole area, clipped to
the product, or the tool returns the product's full extent.
A box's radius was the distance to its farthest corner, which falls short for
large boxes: a whole-world box measured about 10,000 km, so bike-share and
transit selection never considered systems beyond it. The radius now checks
whether the box holds the point opposite its center and otherwise samples
every edge.
Camera packs keep their nearest cameras and the catalog cap thins them
further, so London answered 250 cameras while TfL offers many more. The
catalog now records each pack's full count, tags cameras with their pack,
and serves the packs it trimmed; find_cctv_cameras names them.
A sweep for the same pattern found more answers presented as current and
complete: launches and satellite orbits served from a stale proxy cache, a
regional aircraft fallback read as worldwide, license plate cameras trimmed
or partly loaded, and a radio directory of popular stations read as every
station. The launch and satellite sources now report the proxies' stale
markers, and each answer says what it covers.
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.
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 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.
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.
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.
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.
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.
