## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `verify_npi_numbers`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants an npi lookup, verify npi number, bulk npi lookup or npi taxonomy code lookup for credentialing. Reads live public registry records, checks optional expected names, states and taxonomies, and returns Excel and CSV downloads. Up to 40 NPIs per call; check digits cannot prove issuance. Do not use for patient records or proof of licensure.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `search_npi_providers`

- The name "search_npi_providers" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants an npi registry search, npi search or provider npi lookup by name and state. Reads live public registry records and returns Excel and CSV downloads. Up to 10 searches per call, with at most 10 matches each; give a last name or organization name and a US state. Do not use for insurance acceptance or patient records.
```

## Claude Code permissions
