01 · Install Openstreetmap MCP Server

before you install - you'll need

Set MCP_TRANSPORT_TYPE, MCP_LOG_LEVEL, OSM_OVERPASS_ENDPOINTS before connecting. OTEL_ENABLED is optional or environment-specific per the README.

Claude Code

claude mcp add cyanheads-openstreetmap-mcp-server --transport http https://openstreetmap.caseyjhand.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cyanheads-openstreetmap-mcp-server": {
      "url": "https://openstreetmap.caseyjhand.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

03 · What Openstreetmap MCP Server can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can convert a place name or address to geographic coordinates and structured place data, convert latitude/longitude coordinates to the nearest address or place name, fetch address details for one or more known OSM objects by their IDs, and execute a raw Overpass QL query for advanced spatial operations.

The 6 tools it gives your agent
