mcp-audit SKILL.md skillB
mcp-audit from ulises-jeremias/agent-toolkit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ulises-jeremias/agent-toolkit/mcp-audit@git:20260831.856ee57Pins git:20260831.856ee57 in mdr.lock. Pin the fingerprint instead.

MCP config + implementation security audit — config secrets/auth, unpinned versions, remote vs local, OAuth, env exposure; implementation command injection, SSRF, unsafe args, tool poisoning. Static, evidence-cited.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MCP Audit — Config + Implementation Security Audit **MCP servers** before adopting — static inspection only, never execute remote servers. Use when reviewing `mcp/registry/*.yaml`, `mcp/templates/*/config.template.json`, skill/plugin MCP declarations, or when a static surface scan flags MCP references. **Single skill, two modes** — decision per #379 review: config and implementation scopes meaningfully overlap (both inspect `mcp/registry/*.yaml` + templates), but checklists differ enough to keep separate gates. One skill with two modes avoids duplicating registry parsing while keeping `config` (secret hygiene, version pinning) distinct from `implementation` (command injection, SSRF, tool poisoning). > **Static only:** Do not start or call remote MCP servers during audit. Inspect YAML/JSON, package provenance, tool descriptions, and env handling. ## Modes | Mode | What it checks | Evidence | |------|----------------|----------| | **Config audit** | `mcp/registry/*.yaml` auth, package provenance, version pinning, remote vs local, OAuth, env/secret exposure, permissions | Registry YAML, template JSON, env var names, `docs/MCP.md` | …

How to install
mdr add ulises-jeremias/agent-toolkit/mcp-audit@sha256:b4ee4c43c3df0590The line at the top of this page pins the label git:20260831.856ee57, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
