Overview

AI-generated overview

Lets an assistant look up and search US healthcare providers and organizations in the public NPPES NPI registry by NPI number or criteria.

What it does: This hosted MCP server exposes read-only tools over the public NPPES NPI Registry. nppes_lookup_npi retrieves a provider by NPI number, while nppes_search_individuals, nppes_search_organizations, and nppes_search find providers by various criteria. All tools are read-only, so nothing in the registry is modified.
When to use it: Use it when an assistant needs to verify a US provider or organization by NPI, or to search for providers matching given criteria. It suits healthcare data lookups where the public NPPES registry is the authoritative source.
Requirements: A remote streamable HTTP endpoint; no local install. No credential is required because NPPES is a public data source. On first connect you approve the link, and usage is metered to a private id. Network access to the hosted endpoint is needed.

Before you install

The service is metered: the free plan allows 100 tool calls per month, and Pro is $9/mo or $90/yr for unlimited calls, so heavy use can incur charges. Usage is tied to a private id on first connect. All tools are read-only, but queries are sent to a third-party hosted endpoint.
