Google Maps MCP Server

Streamable HTTP MCP server for Google Maps — search places, get details, and plan routes.

Repository: github.com/iceener/maps-streamable-mcp-server

Use Case

This MCP server is designed for location-aware AI agents running on mobile devices like Apple Watch or iPhone. Your client provides the current position, and the AI can:

Find nearby places (restaurants, stores, gas stations)
Get directions with turn-by-turn navigation
Compare distances to multiple destinations
Check opening hours and ratings before you arrive

It also pairs well with other MCP tools — for example, combining with a Tesla MCP to set navigation destinations directly in your car.

Notice

This repo works in two ways:

As a Node/Hono server for local workflows
As a Cloudflare Worker for remote interactions

Features

✅ Places — Search nearby places, restaurants, landmarks by text or type
✅ Details — Get hours, ratings, reviews, photos, contact info
✅ Routes — Calculate walking, driving, transit directions
✅ Distance Matrix — Compare distances to multiple destinations
✅ Location-aware — All tools work with your current position
✅ Dual Runtime — Node.js/Bun or Cloudflare Workers

Design Principles

LLM-friendly: Unified tools, not 1:1 API mirrors
Watch-ready: Designed for AI agents with location context
Smart defaults: 1km radius, 10 results, walking mode
Clear feedback: Place IDs visible for follow-up queries

Installation

Prerequisites: Bun, Google Cloud project.

0. Client Setup

Your client needs to be aware of the current time and your current location, as both values will be used for searching and planning.

1. Get Google Maps API Key

Go to Google Cloud Console
Create a new project (or select existing)
Navigate to APIs & Services > Library
Enable Places API (New) and Routes API
Go to APIs & Services > Credentials
Click Create Credentials > API Key
(Recommended) Restrict key to Places API and Routes API

2. Local Development

cd google-maps-mcp bun install cp .env.example .env

Edit .env:

PORT=3000 AUTH_ENABLED=true AUTH_STRATEGY=bearer # Generate with: openssl rand -hex 32 BEARER_TOKEN=your-random-auth-token # Your Google Maps API key API_KEY=your-google-maps-api-key

Run:

bun dev # MCP: http://127.0.0.1:3000/mcp

3. Cloudflare Worker (Deploy)

Create KV namespace:

wrangler kv:namespace create TOKENS

Update wrangler.toml with your KV namespace ID
Set secrets:

# Auth token for clients (generate it using: openssl rand -hex 32). This makes the connection to your MCP not open to everyone, but only to those who have this API key. wrangler secret put BEARER_TOKEN # Your Google Maps API key wrangler secret put API_KEY

Deploy:

wrangler deploy

Endpoint: https://<worker-name>.<account>.workers.dev/mcp

Tools

`search_places`

Find places by text query or type near a location.

// Input { query?: string; // "sushi near Central Park" location: { // Required: your current position latitude: number; longitude: number; }; types?: string[]; // ["restaurant", "cafe"] radius?: number; // Meters (default: 1000, max: 50000) filters?: { open_now?: boolean; min_rating?: number; // 0-5 price_levels?: string[]; // PRICE_LEVEL_INEXPENSIVE, etc. }; max_results?: number; // Default: 10, max: 20 sort_by?: "distance" | "rating" | "relevance"; } // Output - Restaurant Name (500m) ★4.5(234) $$ 🟢 Open 123 Main St, New York ID: ChIJN1t_tDeuEmsRUsoyG83frY4

Use query for text search, or types for category-based nearby search.

`get_place`

Get detailed information about a specific place.

// Input { place_id: string; // From search_places results fields?: string[]; // ["basic", "contact", "hours", "reviews", "photos"] } // Output Name: Central Park Address: New York, NY, USA Rating: 4.8 (50000 reviews) Open Now: Yes Hours: Monday: 6:00 AM – 1:00 AM, ... Phone: +1 212-310-6600 Website: https://centralparknyc.org Google Maps: https://maps.google.com/?cid=...

`get_route`

Calculate routes or distance matrix.

// Single destination → detailed route { origin: { latitude: 40.7128, longitude: -74.0060 }; destinations: [{ latitude: 40.7580, longitude: -73.9855 }]; mode?: "walk" | "drive" | "transit"; // Default: "walk" options?: { departure_time?: string; // ISO 8601 or "now" include_steps?: boolean; // Turn-by-turn instructions include_polyline?: boolean; }; } // Multiple destinations → distance matrix { origin: { latitude: 40.7128, longitude: -74.0060 }; destinations: [ { latitude: 40.7580, longitude: -73.9855 }, { latitude: 40.7484, longitude: -73.9857 }, "Empire State Building" // Address or place ID also works ]; mode?: "walk"; } // Output (single) Route Summary: via 5th Ave Total Distance: 5.2 km Total Duration: 62 minutes Steps: 1.1. Head north on Broadway 1.2. Turn right onto E 42nd St ... // Output (matrix) Distances from origin to 3 destinations: - To Times Square: 4.8 km, 58 min - To Empire State: 3.2 km, 38 min - To Central Park: 6.1 km, 73 min

Examples

1. Find nearby coffee shops

{ "name": "search_places", "arguments": { "types": ["cafe"], "location": { "latitude": 40.7128, "longitude": -74.0060 }, "filters": { "open_now": true }, "sort_by": "distance" } }

2. Search by text

{ "name": "search_places", "arguments": { "query": "best pizza in Manhattan", "location": { "latitude": 40.7128, "longitude": -74.0060 }, "max_results": 5 } }

3. Get place details

{ "name": "get_place", "arguments": { "place_id": "ChIJN1t_tDeuEmsRUsoyG83frY4", "fields": ["basic", "hours", "reviews"] } }

4. Walking directions

{ "name": "get_route", "arguments": { "origin": { "latitude": 40.7128, "longitude": -74.0060 }, "destinations": [{ "latitude": 40.7580, "longitude": -73.9855 }], "mode": "walk", "departure_time": "now", "include_steps": true } }

5. Compare distances to multiple places

{ "name": "get_route", "arguments": { "origin": { "latitude": 40.7128, "longitude": -74.0060 }, "destinations": [ "Times Square, NYC", "Central Park, NYC", "Brooklyn Bridge, NYC" ], "mode": "walk" } }

HTTP Endpoints

Endpoint	Method	Purpose
`/mcp`	POST	MCP JSON-RPC 2.0
`/health`	GET	Health check

Environment Variables

Node.js (.env)

Variable	Required	Description
`API_KEY`	✓	Google Maps Platform API key
`BEARER_TOKEN`	✓	Auth token for MCP clients
`PORT`		Server port (default: 3000)
`AUTH_ENABLED`		Enable auth (default: true)
`AUTH_STRATEGY`		`bearer` (default)

Cloudflare Workers

wrangler.toml:

AUTH_ENABLED = "true" AUTH_STRATEGY = "bearer"

Secrets (set via

BEARER_TOKEN — Random auth token for clients
API_KEY — Google Maps Platform API key

KV Namespace:

[[kv_namespaces]] binding = "TOKENS" id = "your-kv-namespace-id"

Troubleshooting

Issue	Solution
401 Unauthorized	Check `BEARER_TOKEN` is set and client sends `Authorization: Bearer <token>`
"API key not configured"	Set `API_KEY` secret: `wrangler secret put API_KEY`
"Places API error 403"	Enable Places API (New) in Google Cloud Console
"Routes API error 404"	Enable Routes API in Google Cloud Console
Invalid Place ID	Place IDs expire. Search again to get fresh IDs
KV namespace error	Run `wrangler kv:namespace create TOKENS` and update wrangler.toml
