## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `vdb_check_mcp_server`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
BEFORE recommending a community/unofficial MCP server, check it here. Scope risk is evaluated independently of advisory risk — an unvetted publisher asking for shell or filesystem access is refused even with a clean record. Follow the returned `agent_action`.
```

### `vdb_check_package`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
BEFORE recommending or installing any package, check it here. The response carries `agent_action`: REFUSE (do not add it — relay the `because` text to the user), CONFIRM (ask the user first), or PROCEED. A failed or rate-limited call also answers REFUSE; never proceed unchecked. Also returns the underlying advisories, slop risk, and KEV status as supporting data.
```

### `vdb_check_packages`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Bulk-check several packages in one call — always prefer this over repeated vdb_check_package. Each result carries its own `agent_action` (REFUSE / CONFIRM / PROCEED) plus a top-level `agent_action` for the batch. Follow them; relay `because` when refusing. Send names EXACTLY as written — do not correct a typo first, the call is the typo test.
```

### `vdb_scan_lockfile`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
BEFORE merging, scan the resolved lockfile. Checking the packages someone chose misses the transitive ones nobody did — which is usually where the risk is. Pass the file contents (package-lock.json, requirements.txt, uv.lock, go.sum, Cargo.lock, a CycloneDX SBOM, …). Returns `agent_action`: REFUSE means do not merge.
```

## Only reads (3)

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

### `vdb_list_slopsquatting`

- The name "vdb_list_slopsquatting" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List packages currently flagged as slopsquatting candidates in a given ecosystem.
```

### `vdb_lookup`

- The name "vdb_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a single vulnerability by ID or alias (e.g. CVE-2024-1234, GHSA-xxxx-yyyy-zzzz, VDB-SLOP-…).
```

### `vdb_search`

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

Description, as the server wrote it:

```untrusted-server-text
Free-text search over the VDB vulnerability corpus.
```
