## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_lead_search`

- The name "cancel_lead_search" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Cancel a queued or running search job. Completed and failed jobs remain immutable.
```

## Changes things (5)

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

### `refine_lead_search`

- The name "refine_lead_search" says "search": a word for reading.
- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a new private search job by changing the brief or criteria of a completed job. The original job stays unchanged.
```

### `research_businesses`

- 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 for a quick synchronous search when the user supplies one natural-language brief and can wait for results in the current tool call. For durable progress, retry, export, or large agent workflows, use start_lead_search instead.
```

### `retry_lead_search`

- The name "retry_lead_search" says "search": a word for reading.
- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a replacement job when a prior job failed or exceeded its execution window. The original job stays available for audit.
```

### `scan_review_pain_points`

- 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
Scan a named business or discover up to three businesses for recent recurring complaints. Returns individually sourced reviews and possible technical solutions. Coverage is sampled; unavailable reviews never mean no problems. Five scans per day. Google reviews require a configured provider.
```

### `start_lead_search`

- The name "start_lead_search" says "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Use for the recommended durable asynchronous workflow. Creates a private queued search job and returns a job id plus jobToken for progress polling, cursor paging, refinement, retry, cancellation, and CSV or JSON export.
```

## Only reads (4)

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

### `explain_crawdar`

- The name "explain_crawdar" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get result semantics, limits, interface URLs, and safe operating guidance. This tool does not consume a search.
```

### `get_lead_search`

- The name "get_lead_search" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read job status or one cursor-paginated result page. Keep jobToken private and pass nextCursor back unchanged.
```

### `sandbox_businesses`

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

Description, as the server wrote it:

```untrusted-server-text
Return deterministic fictional businesses without consuming provider capacity. Use this to test schemas, clients, and agent loops.
```

### `search_businesses`

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

Description, as the server wrote it:

```untrusted-server-text
Use for a quick synchronous search when target, geography, and qualification fields are already structured. Use research_businesses for a plain-language brief, or start_lead_search for durable asynchronous work.
```
