EmbedEarth (E2)

@embedearth/mcp

EmbedEarth (E2) is an open, programmable geographic engine for the physical world. This MCP server gives AI agents structured tools for Search, Compute, Route, Map, and Stratum.

E2 is built as an open alternative to Google Maps Platform, bringing together capabilities commonly spread across Maps, Places, Routes, Geocoding, Autocomplete, and Street View — while adding spatial computation, open geographic data, and local execution.

Why E2

Traditional mapping APIs are built primarily around maps, places, and directions. E2 makes the broader physical world programmable.

Give agents the tools to:

• Search places, infrastructure, observations, nature, civic data, and other real-world features.
• Compute distance, proximity, counts, density, coverage, gaps, and other spatial relationships.
• Map basemaps, features, routes, and application data.
• Route between coordinates or directly to real-world features.
• Stratum geographic datasets for local, offline, and cloud workflows.
• Access street-level imagery and visual observations tied to geographic locations.

For agents coming from Google Maps Platform integrations, E2 can replace many common tool workflows built around Maps, Places, Routes, Geocoding, and street-level imagery while giving agents direct access to broader geographic datasets and spatial computation.

Modes

E2 can run locally or in the cloud. Local datasets are downloaded once per region and reused for future requests, so the same data does not need to be fetched again.

Mode	Purpose
auto	Use local data when available, otherwise cloud.
offline	Download once, then reuse locally.
cloud	Cloud execution with unlimited use using an API key.

API key and limits

An API key is optional for basic cloud use and unlocks full cloud access. Create one at embed.earth and configure it as E2_API_KEY in the MCP host environment; a key is also required for street-level imagery. Without a key, cloud Search, Compute, and Route requests are limited to 60 requests per minute, and e2_stratum query should be treated as one request per second.

Search

e2_search searches the physical world by feature, place, region, or coordinates — places, infrastructure, observations, natural features, civic data, and other geographic datasets through one tool. It returns matching physical-world records as a GeoJSON FeatureCollection.

feature identifies what you want to find; it is a canonical key or numeric ID. Use area for a named region, area_id for an exact region, coordinates for a point lookup, or country_code and state_code for broader geographic selection.

Optional parameters

Parameter	Type	Purpose
area	string | string[]	Search named areas. Mutually exclusive with area_id.
area_id	string | string[]	Search exact area IDs. Mutually exclusive with area.
country_code	string	Select a country, for example US.
state_code	string	Select a state or province, for example NY.
latitude, longitude	number	Search around a coordinate. Provide both.
mode	cloud | offline | auto	Select the execution mode. Defaults to auto.
limit	number	Maximum number of returned features. Defaults to 1000.

{ "feature": "restaurant", "area": "New York", "mode": "auto", "limit": 25 }

{ "feature": "restaurant", "area_id": "4915", "mode": "cloud", "limit": 25 }

{ "feature": "restaurant", "latitude": 40.7128, "longitude": -74.006, "mode": "cloud", "limit": 25 }

{ "feature": "restaurant", "country_code": "US", "state_code": "NY", "mode": "cloud", "limit": 25 }

Compute

e2_compute runs spatial analysis directly against geographic features — find what is nearest, measure distance, count features, calculate density and coverage, detect gaps, or cluster nearby objects — turning geographic data into answers without a separate GIS stack.

feature defines what is being measured, while area or area_id defines the geographic scope. Relationship parameters such as near connect one feature set to another.

Primitive	Purpose
NEAREST	Find the closest features.
DISTANCE	Measure distance between feature sets.
WITHIN	Select features inside a relation distance.
COUNT	Count related features.
DENSITY	Measure feature concentration.
COVERAGE	Measure reached area.
GAPS	Find unreached areas.
CLUSTER	Group nearby features.

{ "primitive": "COUNT", "feature": ["restaurant"], "area_id": "4915", "near": "park", "distanceMeters": 500, "mode": "cloud" }

{ "primitive": "DENSITY", "feature": ["restaurant"], "area": "New York", "near": "park", "distanceMeters": 500, "mode": "auto" }

Routing

Calculate movement through the physical world. Build routes, travel-time matrices, isochrones, map matches, elevation queries, and network-aware searches from coordinates or E2 features — so agents can route to things rather than only fixed coordinates. Use e2_route_to_feature for a coordinate-to-feature route and e2_route for direct routes, matrices, isochrones, map matching, locate, and height.

Set ROUTE_URL only when using your own compatible routing service.

Tool or operation	Purpose
e2_route_to_feature	Route from a coordinate to a matching feature, such as the closest restaurant.
e2_route with route	Build a route between one or more coordinates.
e2_route with matrix	Return travel costs between multiple sources and targets.
e2_route with isochrone	Calculate the area reachable within one or more time limits.
e2_route with mapMatch	Match a recorded coordinate trace to the road network.
e2_route with locate	Resolve a coordinate to the routable network.
e2_route with height	Return elevation data for one or more locations.

{ "feature": "restaurant", "from": [40.7128, -74.006], "mode": "walking" }

{ "operation": "matrix", "body": { "sources": [{ "lat": 40.7128, "lon": -74.006 }], "targets": [{ "lat": 40.7306, "lon": -73.9352 }], "mode": "driving" } }

Maps

e2_map_sources renders E2 data as MapLibre-compatible map sources — the global Planet basemap and PMTiles feature layers. It returns map data metadata rather than rendering a map in the agent conversation, keeping styling and interaction in the client application.

Stratum

e2_stratum is E2's portable data layer for geographic datasets. Discover, download, cache, query, and upload geographic data for local or cloud workflows without maintaining a traditional spatial database. It supports GeoJSON, CSV, Parquet, and SQLite and lets datasets be downloaded once and reused across applications and regions.

Operation	Purpose
cacheList, cacheSet, cacheDelete, cacheClear	Manage verified local data.
featureList, featureSearch, featureInfo	Look up built-in features.
areaList, areaSearch, areaInfo	Look up built-in areas.
dataList, dataInfo	Inspect published data.
download, query	Pull and query Cloud or local data.
upload	Add namespaced local data.

{ "operation": "upload", "path": "./stores.geojson", "database": "./stores.db", "feature": "stores", "namespace": "my-app" }

Geographic Catalog

E2 organizes the physical world into features and areas.

Features describe what exists — places, infrastructure, observations, natural features, imagery-linked records, and other physical-world objects.

Areas describe where — countries, states, cities, and other geographic regions with stable IDs.

Browse the Feature and Area catalogs to discover available inputs across Search, Compute, Route, and Stratum: Catalog Features · Catalog Areas.

Street-level Imagery

EmbedEarth processes billions of street-level images to connect visual observations with geographic features and places. Imagery adds visual context to locations and can surface physical-world features that may not appear in conventional place databases.

Street-level imagery is currently cloud-based and requires an API key and active plan.
