## 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_charity`

- 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
Look up a charity by its official registry identifier - EIN (US), Charity Commission number (GB), RSIN (NL), AHU/Kemenkumham reg number (ID), or a generic registration_number for other countries. Returns the matched charity or null. Use this when the user provides a registry number and wants to confirm what's registered under it.
```

## Only reads (3)

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

### `compare_charities`

- The name "compare_charities" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Side-by-side comparison of 2-5 charities by slug. Returns their integrity scores, program/admin/fundraising ratios, annual revenue, founding year, foundation type, and a deterministic verdict on which has the strongest transparency signal. Use this when the user wants to choose between named charities.
```

### `find_similar`

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

Description, as the server wrote it:

```untrusted-server-text
Given one charity's slug, return up to `limit` other charities in the same country + category. Useful for 'find more like this' recommendations. Excludes the input charity from the result.
```

### `search_charities`

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

Description, as the server wrote it:

```untrusted-server-text
Search the charity registry by free-text name. Returns up to `limit` matches, each with slug, name, country, city/state, foundation_type, integrity_score, and the canonical page URL. Use this BEFORE resources/read when the user names a charity but you don't know its slug. The match is case-insensitive substring on the charity's name.
```
