## Tools

8 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `run_shell` — runs a shell command
- `execute_sql`
- `query_table` — queries a table
- `update_row` — desc
- `scan_text` — Scan a text string or code snippet for insecure MCP server/tool-definition patterns (excessive-agency tool names, shell/eval/SQL/SSRF sinks fed by raw tool inpu
- `scan_file` — Scan a single file for insecure MCP server/tool-definition patterns
- `scan_directory` — Recursively scan an MCP server's codebase for insecure tool-definition patterns. Automatically skips node_modules, .git, dist, and binary files.
- `list_patterns` — List all MCP server security patterns that the auditor can detect, grouped by category

## Install

**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"mcp-server-auditor\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@guardbee/mcp-server-auditor\"\n      ]\n    }\n  }\n}"
```

## Blast radius

Extensive to critical — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs commands; runs on your machine.
- Floor 45, ceiling 73 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
