Photon MCP — komoot-hosted OpenStreetMap geocoder. Strong on partial / typo-tolerant search (Elasticsearch-backed). No auth.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• search(query, lat?, lon?, location_bias_scale?, zoom?, limit?, lang?, osm_tag?, layer?, bbox?) — forward geocoding

• reverse(lat, lon, radius?, lang?, limit?, layer?) — reverse geocoding

Data source

https://photon.komoot.io/ — public, no auth. Fair-use limits. For high volume run your own Photon instance.

Photon vs Nominatim: Photon uses Elasticsearch and is much better at partial / autocomplete-style queries; Nominatim is better for structured-address parsing.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "photon": {
      "url": "https://gateway.pipeworx.io/photon/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Photon data" })

The gateway picks the right tool and fills the arguments automatically.
