## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `check_cve`

- 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
Details for one CVE or GHSA identifier, including whether CISA lists it as actively exploited (KEV) and its EPSS exploitation probability. Use to judge real-world urgency.
```

### `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
Security assessment of one npm or PyPI package: letter grade, findings, known vulnerabilities, deprecation status, and — for MCP servers in our directory — the real resolved dependency count. Use before recommending or installing a package.
```

### `latest_vulns`

- 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
Recently published vulnerabilities from the tracked pool, ranked KEV-first then by EPSS. Use for "what should I worry about this week".
```

## Only reads (1)

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

### `list_mcp_servers`

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

Description, as the server wrote it:

```untrusted-server-text
The MCP server directory with real resolved dependency counts. Use when recommending an MCP server, or to compare how much third-party code candidates pull into the agent. For a graded security assessment of one server, call check_package.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `vulnrable`:

  "permissions": {
    "allow": [
      "mcp__vulnrable__list_mcp_servers"
    ],
    "ask": [
      "mcp__vulnrable__check_package",
      "mcp__vulnrable__check_cve",
      "mcp__vulnrable__latest_vulns"
    ],
    "deny": []
