Install

npm install
npm run build

Run inside a clone of the repository.

This is third-party code. Review the repository files before installing.

What it does

The server gives an agent three tools. One converts an address split into country, city, street and house into coordinates, another does the reverse. The third renders a PNG map from a center and span in degrees and can add placemarks. It runs over stdio or as a stateless HTTP server with an optional Bearer token, which suits n8n.

Who it is for. For developers and analysts who need address coordinates or map images inside an agent.

Good fit when

  • You need coordinates for a list of addresses
  • You want to show points on a map in the agent's reply
  • You want to connect the Yandex geocoder to an n8n workflow

Not a fit when

  • You need to find businesses by name: the Places API is not supported
  • You need interactive maps or routing

Example request

Find coordinates for Kazan, Baumana street 1 and show it on a map

Limitations

Requires two keys from the Yandex developer dashboard: one for JavaScript API and Geocoder, one for Static API. Business search is not supported because that API has no free tier. There is no public npm package, so the server is built from source. Last updated in November 2025.

How to disable. Remove the yandex-maps entry from your MCP client config.

Security check

  • Calls Yandex APIs with the user's keys
  • Without MCP_AUTH_TOKEN, HTTP mode has no authentication

README in short

The README describes three tools and their inputs, how to get two keys in the Yandex developer dashboard and a local build. It gives a Claude Desktop config, HTTP mode with port and token variables, and n8n settings. The limitations section explains the missing business search. MIT licensed.

FAQ

Why can't the agent find a cafe by name?

The server only geocodes known addresses and coordinates. Get the business address from the user, web search or another MCP.
