How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security66
  • The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
  • Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
  • HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
  • The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
  • DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
Schema Quality & AI Usability61
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 1324 tokens (~441/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
  • Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Tool Tokens
npi_get_provider ~219

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.

NameTypeReqDescription
npisyesA single 10-digit NPI, or an array of up to 10. Each is validated as exactly 10 digits before any API call.
NameTypeReqDescription
erroredarrayyesNPIs whose lookups failed with an upstream/transport error (service unavailable, timeout) — distinct from a confirmed miss in notFound. These are unresolved, not absent; retry them.
foundarrayyesFully decoded records for NPIs that resolved.
notFoundarrayyesNPIs that were well-formed but returned no record (deactivated or never enumerated). A confirmed absence, not a failure.
noticestringGuidance when some or all NPIs returned nothing.
totalCountnumberyesNumber of provider records that resolved from the requested NPIs.

No examples provided.

npi_lookup_taxonomy ~365

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.

NameTypeReqDescription
codestringFor mode "get": the exact NUCC taxonomy code (e.g. "207RC0000X").
groupingstringFor mode "browse": filter to a top-level grouping by case-insensitive substring (e.g. "physicians").
limitintegerMaximum entries to return for resolve/browse (1–50). Ignored for get.
modestringyesresolve: plain term → codes. get: exact code → entry. browse: walk the hierarchy.
querystringFor mode "resolve": the plain-language specialty term to resolve (e.g. "pediatric cardiologist").
sectionstringFor mode "browse": filter by NPI section — Individual (NPI-1) or Non-Individual (NPI-2).
skipintegerEntries to skip before the page, for paging past a truncated resolve/browse result (0–1000). Keep the same query/filters and limit, raise skip by limit each call. Ignored for get.
NameTypeReqDescription
capnumberThe limit that was applied.
matchesarrayyesMatching taxonomy entries. For mode "get" this is the single requested entry; for "resolve"/"browse" it is the ranked/sorted matches up to limit.
noticestringGuidance — how to page a truncated result with skip, or how to broaden when nothing matched.
shownnumberNumber of entries returned.
truncatedbooleanTrue when the list was capped at `limit` (more entries may match).

No examples provided.

npi_search_providers ~605

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.

NameTypeReqDescription
citystringPractice-location city.
first_namestringIndividual first name. Trailing wildcard "*" allowed with at least 2 leading characters.
last_namestringIndividual last name. Trailing wildcard "*" allowed with at least 2 leading characters.
limitintegerMaximum providers to return (1–200; the registry caps at 200).
name_searchstringConvenience shortcut: a single person's name, split into first/last heuristically. For precise control use first_name/last_name.
organization_namestringOrganization name (implies provider_type organization). Trailing wildcard "*" allowed with at least 2 leading characters.
postal_codestringPractice-location postal/ZIP code (5 or 9 digits).
provider_typestringRestrict to individuals (NPI-1) or organizations (NPI-2). Omit to search both.
skipintegerResults to skip for pagination (0–1000). Only the first 1200 matches are reachable; skip beyond 1000 silently returns the same window — narrow the query instead of paging further.
specialtystringPlain-language specialty (e.g. "pediatric cardiologist"), resolved through the bundled NUCC taxonomy to exact descriptions before searching. The matched taxonomy is echoed in the result. Mutually exc…
state2-letter state code (e.g. "WA"). The registry rejects state-only searches — pair it with another criterion. Blank values from form-based clients are treated as omitted.
taxonomy_descriptionstringExact NUCC taxonomy description for direct passthrough — use when the taxonomy description is already known. Mutually exclusive with specialty.
NameTypeReqDescription
appliedTaxonomyDescriptionstringThe single taxonomy_description sent to the registry (from specialty resolution or the raw escape hatch).
capnumberThe limit that was applied.
noticestringGuidance — pagination ceiling, page-size-not-total caveat, or how to broaden an empty result.
providersarrayyesMatching provider rows (up to limit).
resolvedTaxonomiesarrayThe taxonomy candidates the specialty term resolved to; the first was sent to the registry. Re-run with taxonomy_description to pick a different one.
shownnumberNumber of providers returned.
truncatedbooleanTrue when the returned page hit the limit — more may match.
