Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`count_by_specialty`read-only	How many providers does the NPI Registry list for a specialty, optionally in a state or ZIP prefix? Exact up to 1,200; beyond that it says "1200+" and points to the full-list route. Up to 5 specialties per call.
`lookup_npi`read-only	Fetch 1-20 providers by NPI number from the live CMS NPI Registry: name, credential, status, primary specialty (taxonomy), practice address and phone. Check digits are validated first; invalid and unknown numbers are reported separately.
`search_providers`read-only	Search the live NPI Registry by first/last name, organization name, specialty (taxonomy description as the registry writes it, e.g. "Family Medicine", "Dentist"), state (2 letters), city or ZIP. Needs at least one of name, organization, specialty, city or ZIP (a state alone is refused by CMS). Returns up to 50 rows and how many exist (capped at 1,200). Full lists beyond that: https://tuper.app/tools/npi-list-by-specialty/?src=mcp-npi
`validate_npi`read-only	Offline check of up to 50 NPI numbers: 10 digits and the Luhn check digit (prefix 80840). Does not call CMS, so it cannot say whether the number is issued; use lookup_npi for that.

Schemas: list_tools.
