- **17 tools** — 14 atomic + 3 composite (explore-area, plan-route, compare-places) - **3 modes** — stdio, StreamableHTTP, standalone exec CLI - **Agent Skill** — built-in skill definition teaches AI how to chain geo tools ([`skills/google-maps/`](./skills/google-maps/)) ### vs Google Grounding Lite | | This project | [Grounding Lite](https://cloud.google.com/blog/products/ai-machine-learning/announcing-official-mcp-support-for-google-services) | |---|---|---| | Tools | **17** | 3 | | Geocoding | Yes | No | | Step-by-step directions | Yes | No | | Elevation | Yes | No | | Distance matrix | Yes | No | | Place details | Yes | No | | Timezone | Yes | No | | Weather | Yes | Yes | | Air quality | Yes | No | | Map images | Yes | No | | Composite tools (explore, plan, compare) | Yes | No | | Open source | MIT | No | | Self-hosted | Yes | Google-managed only | | Agent Skill | Yes | No | ### Quick Start ```bash # stdio (Claude Desktop, Cursor, etc.) npx @cablate/mcp-google-map --stdio # exec CLI — no server needed npx @cablate/mcp-google-map exec geocode '{"address":"Tokyo Tower"}' # HTTP server npx @cablate/mcp-google-map --port 3000 --apikey "YOUR_API_KEY" ``` ## Special Thanks Special thanks to [@junyinnnn](https://github.com/junyinnnn) for helping add support for `streamablehttp`. ## Available Tools | 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 — 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 — 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 — returned inline for the user to see directly. | | `maps_batch_geocode` | Geocode up to 50 addresses in one call — returns coordinates for each. | | `maps_search_along_route` | Search for places along a route between two points — ranked by minimal detour time. | | **Composite Tools** | | | `maps_explore_area` | Explore what's around a location — searches multiple place types and gets details in one call. | | `maps_plan_route` | Plan an optimized multi-stop route — uses Routes API waypoint optimization (up to 25 stops) for efficient ordering. | | `maps_compare_places` | Compare places side-by-side — searches, gets details, and optionally calculates distances. | All tools are annotated with `readOnlyHint: true` and `destructiveHint: false` — MCP clients can auto-approve these without user confirmation. > **Prerequisite**: Enable **Places API (New)** and **Routes API** in [Google Cloud Console](https://console.cloud.google.com) before using place-related and routing tools. ## Installation ### Method 1: stdio (Recommended for most clients) Works with Claude Desktop, Cursor, VS Code, and any MCP client that supports stdio: ```json { "mcpServers": { "google-maps": { "command": "npx", "args": ["-y", "@cablate/mcp-google-map", "--stdio"], "env": { "GOOGLE_MAPS_API_KEY": "YOUR_API_KEY" } } } } ``` **Reduce context usage** — If you only need a subset of tools, set `GOOGLE_MAPS_ENABLED_TOOLS` to limit which tools are registered: ```json { "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 17 tools (default). ### Method 2: HTTP Server For multi-session deployments, per-request API key isolation, or remote access: ```bash npx @cablate/mcp-google-map --port 3000 --apikey "YOUR_API_KEY" ``` Then configure your MCP client: ```json { "mcpServers": { "google-maps": { "type": "http", "url": "http://localhost:3000/mcp" } } } ``` ### Server Information - **Transport**: stdio (`--stdio`) or Streamable HTTP (default) - **Tools**: 17 Google Maps tools (14 atomic + 3 composite) — filterable via `GOOGLE_MAPS_ENABLED_TOOLS` ### CLI Exec Mode (Agent Skill) Use tools directly without running the MCP server: ```bash npx @cablate/mcp-google-map exec geocode '{"address":"Tokyo Tower"}' npx @cablate/mcp-google-map exec search-places '{"query":"ramen in Tokyo"}' ``` All 17 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`. See [`skills/google-maps/`](./skills/google-maps/) for the agent skill definition and full parameter docs. ### Batch Geocode Geocode hundreds of addresses from a file: ```bash 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 Key Configuration API keys can be provided in three ways (priority order): 1. **HTTP Headers** (Highest priority) ```json { "mcp-google-map": { "transport": "streamableHttp", "url": "http://localhost:3000/mcp", "headers": { "X-Google-Maps-API-Key": "YOUR_API_KEY" } } } ``` 2. **Command Line** ```bash mcp-google-map --apikey YOUR_API_KEY ``` 3. **Environment Variable** (.env file or command line) ```env GOOGLE_MAPS_API_KEY=your_api_key_here MCP_SERVER_PORT=3000 ``` ## Development ### Local Development ```bash # Clone the repository git clone https://github.com/cablate/mcp-google-map.git cd mcp-google-map # Install dependencies npm install # Set up environment variables cp .env.example .env # Edit .env with your API key # Build the project npm run build # Start the server npm start # Or run in development mode npm run dev ``` ### Testing ```bash # Run smoke tests (no API key required for basic tests) npm test # Run full E2E tests (requires GOOGLE_MAPS_API_KEY) npm run test:e2e ``` ### Project Structure ``` src/ ├── cli.ts # CLI entry point ├── config.ts # Tool registration and server config ├── index.ts # Package exports ├── core/ │ └── BaseMcpServer.ts # MCP server with streamable HTTP transport ├── services/ │ ├── NewPlacesService.ts # Google Places API (New) client │ ├── PlacesSearcher.ts # Service facade layer │ ├── RoutesService.ts # Google Routes API client (directions, distance matrix, waypoint optimization) │ └── toolclass.ts # Google Maps API client (geocoding, timezone, elevation, static map) ├── tools/ │ └── maps/ │ ├── searchNearby.ts # maps_search_nearby tool │ ├── searchPlaces.ts # maps_search_places tool │ ├── placeDetails.ts # maps_place_details tool │ ├── geocode.ts # maps_geocode tool │ ├── reverseGeocode.ts # maps_reverse_geocode tool │ ├── distanceMatrix.ts # maps_distance_matrix tool │ ├── directions.ts # maps_directions tool │ ├── elevation.ts # maps_elevation tool │ ├── timezone.ts # maps_timezone tool │ ├── weather.ts # maps_weather tool │ ├── airQuality.ts # maps_air_quality tool │ ├── staticMap.ts # maps_static_map tool │ ├── batchGeocode.ts # maps_batch_geocode tool │ ├── searchAlongRoute.ts # maps_search_along_route tool │ ├── exploreArea.ts # maps_explore_area (composite) │ ├── planRoute.ts # maps_plan_route (composite) │ └── comparePlaces.ts # maps_compare_places (composite) └── utils/ ├── apiKeyManager.ts # API key management └── requestContext.ts # Per-request context (API key isolation) tests/ └── smoke.test.ts # Smoke + E2E test suite skills/ ├── google-maps/ # Agent Skill — how to USE the tools │ ├── SKILL.md # Tool map, recipes, invocation │ └── references/ │ ├── tools-api.md # Tool parameters + scenario recipes │ ├── travel-planning.md # Travel planning methodology │ └── local-seo.md # Local SEO / Google Business Profile ranking analysis └── project-docs/ # Project Skill — how to DEVELOP/MAINTAIN ├── SKILL.md # Architecture overview + onboarding └── references/ ├── architecture.md # System design, code map, 9-file checklist ├── google-maps-api-guide.md # API endpoints, pricing, gotchas ├── geo-domain-knowledge.md # GIS fundamentals, Japan context └── decisions.md # 10 ADRs (design decisions + rationale) ``` ## Tech Stack -

**Logistics optimization** — "Route these 12 deliveries efficiently from the warehouse" (plan-route) - **Field sales** — "Visit 6 clients in Chicago, minimize drive time, find lunch spots" (plan-route + search-nearby) - **Disaster response** — "Nearest open hospitals? Am I in a flood zone?" (search-nearby + elevation) - **Content creation** — "Top 5 neighborhoods in Austin with restaurant density and airport distance" (explore-area + distance-matrix) - **Accessibility** — "Wheelchair-accessible restaurants, avoid steep routes" (search-nearby + place-details + elevation) - **Local SEO** — "Audit my restaurant's ranking vs competitors within 1km" (search-places + compare-places + explore-area) ## Changelog See [CHANGELOG.md](./CHANGELOG.md) for version history. ## License MIT ## Contributing Community participation and contributions are welcome! - Submit Issues: Report bugs or provide suggestions - Create Pull Requests: Submit code improvements - Documentation: Help improve documentation ## Contact - Email: [reahtuoo310109@gmail.com](mailto:reahtuoo310109@gmail.com) - GitHub: [CabLate](https://github.com/cablate/) ## Star History
