Postcodes MCP — wraps postcodes.io UK postcode API (free, no auth)

Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.

Tool	Description
`lookup_postcode`	Get geographic details for a UK postcode (e.g., 'SW1A 1AA'). Returns coordinates, region, district, ward, and constituency.
`nearest_postcodes`	Find nearby UK postcodes sorted by distance from a given postcode (e.g., 'SW1A 1AA'). Returns list with coordinates.
`validate_postcode`	Validate a UK postcode format (e.g., 'SW1A 1AA'). Returns whether it's valid and format details.
`random_postcode`	Get a random valid UK postcode with full geographic details. Returns coordinates, region, district, ward, and constituency.

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

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

Or connect to the full Pipeworx gateway for access to all 250+ data sources:

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

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

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

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