Overview

What is Mapsi Mcp?

Mapsi Mcp is an MCP (Model Context Protocol) server that provides 18 geospatial tools for AI coding assistants. It connects Claude Code, Cursor, Windsurf, and any MCP-compatible IDE directly to the Mapsi API. The service is built on OpenStreetMap data, uses self-hosted infrastructure, and avoids vendor lock-in to Google Maps.

How to use Mapsi Mcp?

Obtain a free API key at mapsi.dev/console/api-keys (1,000 calls/day, no credit card required). Add the server configuration to your IDE’s MCP settings (e.g., ~/.claude.json, ~/.cursor/mcp.json, or Windsurf’s mcp_config.json) using npx -y mapsi-mcp and the MAPSI_API_KEY environment variable. Restart your IDE, then ask your AI assistant in plain English.

FAQ from Mapsi Mcp

What is the free tier limit?

The free plan includes 1,000 API calls per day with a batch size of 10. No credit card is required to sign up.

Which transport modes does the route tool support?

The route tool supports auto, truck, bicycle, pedestrian, and motor_scooter modes.

What should I do if route returns “no route found”?

Call the nearest_road tool to snap the point to a routable road, then retry the route with the snapped coordinates.

How do I authenticate API calls and tile requests?

API calls use the X-API-Key header, handled automatically by the MCP server via the MAPSI_API_KEY environment variable. Tile URLs include a ?key= query parameter.

Can I geocode many addresses at once instead of looping?

Yes, use batch_geocode for up to 30,000 addresses (limits depend on your plan). Never loop the single geocode tool for bulk data.
