What it does & operational scope
Google Maps MCP Server bridges language models to Google Maps Platform APIs using local stdio transport. It exposes endpoints for forward and reverse geocoding, distance matrix calculations between coordinates, topographic altitude queries, and place detail searches including ratings and operational hours.
Google Maps MCP Server is an open-source Model Context Protocol server licensed under MIT that connects AI assistants to Google Maps Platform geocoding and distance calculations over stdio.
Your AI coding agent requires live access to Google Maps tools and resources over local IPC or streamable transport.
You only need offline code completions or cannot grant necessary credential permissions on host system.
Client configuration & wire setup
Prerequisites: Node.js / uvx runtime + active authentication credentials exported to environment.

Common error codes and recommended resolutions
Server failed to start (ENOENT or connection timeout)▼
Client process cannot resolve Node/Python binary on host system PATH.
Provide full absolute path to the binary in your client config (e.g. "/opt/homebrew/bin/node" or "C:\\Program Files\\nodejs\\node.exe").
Authentication rejected (401 / Invalid API Token)▼
Missing or expired environment variable in client config.
Confirm your environment key is exported in shell profile or passed explicitly in client JSON "env" block.
Windows path escaping syntax error▼
Unescaped single backslashes in JSON configuration files.
Use forward slashes or double backslashes in path strings (e.g., "C:/Users/name/.env" or "C:\\Users\\name").
Technical trade-offs and operational friction
+ Backed by Google Maps Platform's extensive global geographic database.
+ Provides accurate real-time transit and driving distance estimations.
+ Standard stdio integration requiring only a valid Google Cloud API key.
− Lacks local offline map caching, incurring commercial Google Maps Platform billing charges on repeated geographic lookups.
− High-resolution photo and route geometry endpoints return oversized JSON payloads that rapidly consume token allotments.
