postcodes

Wraps the free postcodes.io API to give Claude geographic tools for UK postcodes without requiring authentication. You get four operations: lookup a postcode for coordinates and administrative boundaries like region, district, ward, and constituency; find nearby postcodes sorted by distance; validate postcode format; or pull a random valid postcode. Useful when you need to resolve UK addresses to lat/long, check if user input is a real postcode, or build location aware features for UK users. Runs through Pipeworx's gateway, which can bundle this with 673+ other data sources if you need broader API access beyond postcodes.
