## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `calculate_per_diem`

- 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 a per diem calculator, gsa per diem calculator, or travel per diem calculator with per diem meal deduction and a downloadable XLSX/CSV expense worksheet. Covers bundled GSA CONUS FY2026/FY2027 only; up to 10 trips, 10 contiguous stops per trip, 92 days between arrival and departure, and 400 day rows per call. Furnished government or registration meals reduce allowances; common-carrier meals and complimentary hotel breakfasts are not deductions. Same-day travel requires more than 12 hours; no times are taken. Do not use for OCONUS, lodging taxes, agency policies or FY2028.
```

## Only reads (1)

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

### `find_per_diem_rates`

- The name "find_per_diem_rates" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants gsa per diem rates, federal per diem rates, per diem rates 2027 or m&ie rates by month, with XLSX and CSV downloads. Looks up 1 to 25 ZIP codes or City, ST locations in bundled GSA CONUS FY2026/FY2027 tables. The default fiscal year uses today in America/New_York. Ambiguous ZIPs return an item error; use calculate_per_diem with county to disambiguate. Do not use for OCONUS or FY2028.
```
