Retrieve French communes (municipalities) associated with a postal code.

This tool queries the IGN API Carto codes-postaux module to find all communes that share a given postal code. In France, a postal code can cover multiple communes, and this tool returns all of them.

Args:

Returns: For JSON format: [ { "codePostal": "75001", "codeCommune": "75101", "nomCommune": "Paris 1er Arrondissement", "libelleAcheminement": "PARIS" } ]

Examples:

• "What communes are in postal code 75001?" -> code_postal="75001"

• "Find cities for zip 69000" -> code_postal="69000"
