On-demand audit of MCP usage. Reads the MCP audit log (mcp-audit.jsonl) written by the mcp-call-gate hook, surfaces blocked calls, rate-limit hits, suspicious input patterns. Companion to mcp-call-gate hook (which produces the audit log).
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
> **AI-consumed reference.** Optimized for Claude to read during execution. > Human-readable explanation: see [docs/architecture/HIERARCHICAL_PLANNING.md](../../../docs/architecture/HIERARCHICAL_PLANNING.md) > or [docs/getting-started/](../../../docs/getting-started/) depending on topic. # MCP Security Auditor **STATUS — v3.7.0-rc.1.** Read-only auditor; does not enforce — that's `mcp-call-gate.cjs`'s job. ## Behavior 1. Read `<security-dir>/mcp-audit.jsonl` (append-only; produced by `hooks/mcp-call-gate.cjs`). Resolve `<security-dir>` the same way the writer does — see `hooks/lib/security-dir.cjs`: `$AF_SECURITY_DIR`, else `.claude/security/` if it exists, else `.aura/security/`. Do NOT hardcode one of them: read the first that exists, and report "no audit log yet" if neither does. 2. Group entries by: - Agent → MCP server → method - Time bucket (last 1h / 24h / session) - Status (success / blocked / rate-limited) 3. Project to TOON (via `scripts/json-to-toon.cjs --schema generic` or custom fields) — NEVER load raw JSONL into context 4. Surface findings categorized as: - **Blocked calls** (`BLOCKED:true`) — deserve investigation …

How to install
mdr add nguyenthienthanh/aura-frog/mcp-security-auditor@sha256:88cf9a1108a7f00dThe line at the top of this page pins the label git:20260819.7ca3bbc, 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.
