The Postal Data API MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Postal Data API account. It provides structured and secure access to global postal code and location data, so your agent can validate postal codes, look up locations and coordinates, search postal codes by city, retrieve regional metadata, and check service information on your behalf.
- Postal code validation: Have your agent check whether a postal code exists without treating an invalid code as an execution error.
- Bulk postal code checks: Instruct your agent to validate up to 1,000 postal codes at once, including codes from different countries.
- Location and coordinate lookup: Let the agent find the city, region, and coordinates associated with a postal code.
- City-based postal code search: Direct your agent to find postal codes for a city and optional region, including close matches.
- Regional details and service status: Have your agent retrieve available timezone, county, elevation, and administrative details for a postal code, or check coverage, guidance, balance, and rate-limit status.
