Postcodes

UK postcode geographic lookup. Get coordinates, administrative districts, parliamentary constituencies, and NHS regions for any postcode in the United Kingdom.

What you get

• lookup_postcode -- Full geographic and administrative details for a UK postcode
• nearest_postcodes -- Find neighbouring postcodes to a given one
• validate_postcode -- Check if a postcode string is valid
• random_postcode -- Grab a random valid postcode with full details

Try it

Look up 10 Downing Street's postcode:

curl -X POST https://gateway.pipeworx.io/postcodes/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"lookup_postcode","arguments":{"postcode":"SW1A 2AA"}}}'

Good to know

Postcodes are case-insensitive and spaces are optional -- SW1A1AA works the same as sw1a 1aa. The response includes ONS codes, lat/lon coordinates, and full administrative geography down to ward and parish level.
