What this server can do

3 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

npi_get_provider(npis)
Fetch the complete NPPES record for one or more NPI numbers (up to 10 per call). Decodes an NPI from a claim, prescription, or another health data source into a fully populated provider profile: every taxonomy with its primary flag, license number and state; all practice and mailing addresses; credential, sex, sole-proprietor flag; enumeration and last-updated dates; active/deactivated status; secondary identifiers (Medicaid, etc.); and FHIR/Direct endpoints. The 10-digit NPI format is validated before any API call. Reports partial success: well-formed NPIs with no registry record (deactivated or never enumerated) land in notFound, while NPIs whose lookup hit an upstream error (registry unavailable, timeout) land in errored — kept distinct from confirmed misses — rather than failing the whole call. Required: npis.
npi_lookup_taxonomy(code, mode, skip, limit, query, section, grouping)
Resolve and browse the NUCC Healthcare Provider Taxonomy — the specialty code set NPPES uses — fully offline (bundled). Mode `resolve` turns a plain-language specialty (e.g. "cardiologist", "heart doctor") into matching taxonomy codes and their canonical descriptions; mode `get` returns the full entry for an exact code; mode `browse` walks the hierarchy (grouping → classification → specialization), optionally filtered by grouping and by NPI section (Individual/NPI-1 vs Non-Individual/NPI-2). Grounding a plain-language specialty here before calling npi_search_providers ensures the correct taxonomy code is sent rather than returning nothing. Required: mode.
npi_search_providers(city, skip, limit, state, last_name, specialty, first_name, name_search, postal_code, provider_type, organization_name, taxonomy_description)
Search the NPPES NPI registry for individual practitioners and healthcare organizations by name, organization name, location, provider type, and specialty. The specialty filter accepts plain-language terms (e.g. "cardiologist", "pediatric cardiologist") and resolves them through the bundled NUCC taxonomy to the registry's exact taxonomy descriptions before searching; the resolved taxonomy is echoed back so you can see what was actually searched. Pass location as the dedicated city/state/postal_code inputs, not inside specialty. Returns a compact row per provider — NPI, name, primary specialty, city/state/ZIP, type, and active/deactivated status — suitable for disambiguation; call npi_get_provider with an NPI for the full record. At least one search criterion is required, and the registry rejects state-only searches (pair state with another filter). The registry does not treat location as a hard filter for specialty searches, so location-constrained results are post-filtered server-side to the requested city/state/postal_code. The registry never reports a true match total and only the first 1200 matches are reachable, so broad queries are capped — narrow with more filters.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

These share tags the maintainers applied themselves, such as healthcare, provider-directory, cyanheads, health-tech. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
