Postali integrations

Connect Postali to any other app, or use it from your AI client over MCP. Postali is a lookup service for Mexican postal codes (códigos postales). Callers can submit a five-digit code and retrieve the matching colonias along with the municipio, estado and ciudad they belong to, and search in the other direction by state or municipality to list the codes it contains. Useful for autofilling Mexican shipping and billing addresses. No credentials required.

Any of Postali's 8 actions, including Find postal codes in bulk, Find postal locations by query, Get municipality and Get postal code. Your agent maps the data both ways and tests every scenario before it ships.

Which apps can Postali connect to?

Is there a free plan?
