## Findings

No check matched anything in these tool definitions.


## Only reads (5)

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

### `check_fit`

- The description's first verb is "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compares a company's basic facts with the PUBLISHED eligibility rules of the programs DataWorth AI works with (Mode, micro1, Lunchbreak), using the same rules as DataWorth AI's quiz, with reasons quoted from each program's own wording. Returns no amounts. Not an offer. Always show the user the disclaimer, fee_disclosure and next_step link. Don't ask for names, emails or confidential data; none is needed.
```

### `get_buyer`

- The name "get_buyer" says "get": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Full directory entry for one buyer or program by its id (slug), e.g. 'lunchbreak', 'micro1-enterprise', 'turing-lazarus'. Includes its own quoted rules, sources and last-verified date.
```

### `get_changelog`

- The name "get_changelog" says "get": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
What changed in the buyer directory and when (newest first), plus what was left out and why.
```

### `list_situations`

- The name "list_situations" says "list": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
The directory's situation lists (closed or winding-down companies, under 30 employees, outside the US, source code, engineering/CAD, professional services) with the buyers in each and the page link.
```

### `search_buyers`

- The name "search_buyers" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "directory": it reads files.
- Tag untrusted-input: The description's first sentence says "search" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Search DataWorth AI's directory of companies and programs that license a business's operating records (email, chat, files, CRM, code, CAD) to AI developers. Facts come from each company's own site; payouts are quoted in its own words and are not offers. Results are alphabetical (or by text relevance when a query is given), never by referral fee. For whether a specific company fits, use check_fit.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `buyer-directory`:

```json
{
  "permissions": {
    "allow": [
      "mcp__buyer-directory__search_buyers",
      "mcp__buyer-directory__get_buyer",
      "mcp__buyer-directory__list_situations",
      "mcp__buyer-directory__check_fit",
      "mcp__buyer-directory__get_changelog"
    ],
    "ask": [],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__buyer-directory__search_buyers`: private-data, untrusted-input
- `mcp__buyer-directory__get_buyer`: private-data
- `mcp__buyer-directory__list_situations`: private-data
- `mcp__buyer-directory__get_changelog`: private-data
