| Tool | Description |
|---|---|
maps_search_nearby |
Find places near a location by type (restaurant, cafe, hotel, etc.). Supports filtering by radius, rating, and open status. |
maps_search_places |
Free-text place search (e.g., "sushi restaurants in Tokyo"). Supports location bias, rating, open-now filters. |
maps_place_details |
Get full details for a place by its place_id β reviews, phone, website, hours. Optional maxPhotos param returns photo URLs. |
maps_geocode |
Convert an address or landmark name into GPS coordinates. |
maps_reverse_geocode |
Convert GPS coordinates into a street address. |
maps_distance_matrix |
Calculate travel distances and times between multiple origins and destinations. |
maps_directions |
Get step-by-step navigation between two points with route details. |
maps_elevation |
Get elevation (meters above sea level) for geographic coordinates. |
maps_timezone |
Get timezone ID, name, UTC/DST offsets, and local time for coordinates. |
maps_weather |
Get current weather conditions or forecast β temperature, humidity, wind, UV, precipitation. |
maps_air_quality |
Get air quality index, pollutant concentrations, and health recommendations by demographic group. |
maps_static_map |
Generate a map image with markers, paths, or routes β returned inline for the user to see directly. |
maps_batch_geocode |
Geocode up to 50 addresses in one call β returns coordinates for each. |
maps_search_along_route |
Search for places along a route between two points β ranked by minimal detour time. |
| Composite Tools | |
maps_explore_area |
Explore what's around a location β searches multiple place types and gets details in one call. |
maps_plan_route |
Plan an optimized multi-stop route β uses Routes API waypoint optimization (up to 25 stops) for efficient ordering. |
maps_compare_places |
Compare places side-by-side β searches, gets details, and optionally calculates distances. |
maps_local_rank_tracker |
Track a business's local search ranking across a geographic grid β like LocalFalcon. Supports up to 3 keywords for batch scanning. Returns rank at each point, top-3 competitors, and metrics (ARP, ATRP, SoLV). |
All tools are annotated with readOnlyHint: true and destructiveHint: false β MCP clients can auto-approve these without user confirmation.
Prerequisite: Enable Places API (New) and Routes API in Google Cloud Console before using place-related and routing tools.
Works with Claude Desktop, Cursor, VS Code, and any MCP client that supports stdio:
{
"mcpServers": {
"google-maps": {
"command": "npx",
"args": ["-y", "@cablate/mcp-google-map", "--stdio"],
"env": {
"GOOGLE_MAPS_API_KEY": "YOUR_API_KEY"
}
}
}
}Reduce context usage β If you only need a subset of tools, set GOOGLE_MAPS_ENABLED_TOOLS to limit which tools are registered:
{
"env": {
"GOOGLE_MAPS_API_KEY": "YOUR_API_KEY",
"GOOGLE_MAPS_ENABLED_TOOLS": "maps_geocode,maps_directions,maps_search_places"
}
}Omit or set to * for all 18 tools (default).
For multi-session deployments, per-request API key isolation, or remote access:
npx @cablate/mcp-google-map --port 3000 --apikey "YOUR_API_KEY"
# Bind to all interfaces for remote access (e.g. Docker, LAN)
npx @cablate/mcp-google-map --host 0.0.0.0 --port 3000 --apikey "YOUR_API_KEY"Then configure your MCP client:
{
"mcpServers": {
"google-maps": {
"type": "http",
"url": "http://localhost:3000/mcp"
}
}
}- Transport: stdio (
--stdio) or Streamable HTTP (default) - Tools: 18 Google Maps tools (14 atomic + 4 composite) β filterable via
GOOGLE_MAPS_ENABLED_TOOLS
Use tools directly without running the MCP server:
npx @cablate/mcp-google-map exec geocode '{"address":"Tokyo Tower"}'
npx @cablate/mcp-google-map exec search-places '{"query":"ramen in Tokyo"}'All 18 tools available: geocode, reverse-geocode, search-nearby, search-places, place-details, directions, distance-matrix, elevation, timezone, weather, air-quality, static-map, batch-geocode-tool, search-along-route, explore-area, plan-route, compare-places, local-rank-tracker. See skills/google-maps/ for the agent skill definition and full parameter docs.
Geocode hundreds of addresses from a file:
npx @cablate/mcp-google-map batch-geocode -i addresses.txt -o results.json
cat addresses.txt | npx @cablate/mcp-google-map batch-geocode -i -Input: one address per line. Output: JSON with { total, succeeded, failed, results[] }. Default concurrency: 20 parallel requests.
API keys can be provided in three ways (priority order):
-
HTTP Headers (Highest priority)
{ "mcp-google-map": { "transport": "streamableHttp", "url": "http://localhost:3000/mcp", "headers": { "X-Google-Maps-API-Key": "YOUR_API_KEY" } } } -
Command Line
mcp-google-map --apikey YOUR_API_KEY
-
Environment Variable (.env file or command line)
GOOGLE_MAPS_API_KEY=your_api_key_here MCP_SERVER_PORT=3000 MCP_SERVER_HOST=0.0.0.0

These are the real-world scenarios driving our tool decisions:
- Travel planning β "Plan a day trip in Tokyo" (geocode β search β directions β weather)
- Real estate analysis β "Analyze this neighborhood: schools, commute, flood risk" (search-nearby Γ N + elevation + distance-matrix)
- Logistics optimization β "Route these 12 deliveries efficiently from the warehouse" (plan-route)
- Field sales β "Visit 6 clients in Chicago, minimize drive time, find lunch spots" (plan-route + search-nearby)
- Disaster response β "Nearest open hospitals? Am I in a flood zone?" (search-nearby + elevation)
- Content creation β "Top 5 neighborhoods in Austin with restaurant density and airport distance" (explore-area + distance-matrix)
- Accessibility β "Wheelchair-accessible restaurants, avoid steep routes" (search-nearby + place-details + elevation)
- Local SEO β "Audit my restaurant's ranking vs competitors within 1km" (search-places + compare-places + explore-area)
