## Description

This MCP server provides healthcare provider lookup capabilities through the National Provider Identifier (NPI) registry, enabling AI assistants to search for individual practitioners and healthcare organizations across the United States. Built by Eliot Kristan using Python with FastMCP and httpx, it offers flexible search functionality with wildcard support for names, organizations, cities, and specialties, along with location-based filtering by state and postal code, and direct NPI number lookup for specific providers. The implementation features comprehensive provider information retrieval including contact details, practice locations, taxonomies, credentials, and organizational hierarchies, with configurable result limits and robust error handling for API interactions, making it valuable for healthcare research workflows, provider verification processes, and building AI assistants that need programmatic access to official healthcare provider data without manual registry navigation.
