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.
Tools
| 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. |
Quick Start
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"
}
}
}
Using with ask_pipeworx
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.
