aisec-suite

One command that runs three AI-security scanners on a repository and writes SARIF for GitHub code scanning.

No third-party code is executed: tool definitions are read from source, not by launching the server.

pip install "aisec-suite[scanners]"   # also installs pyhroff-mcpaudit, memsentry, pyhroff-ragsentry from PyPI
aisec scan . --sarif aisec.sarif --fail-on high
aisec scan . --rag ./docs --json findings.json

Exit codes: 0 clean, 1 a finding at or above --fail-on, 2 a scanner crashed (so a clean result can't be trusted; only with --fail-on). Use --include-tests to also extract tools from tests/examples/fixtures.

Adopting it on an existing repo without a wall of red

aisec scan . --write-baseline .aisec-baseline.json     # accept what exists today
aisec scan . --baseline .aisec-baseline.json --fail-on high   # CI now fails only on NEW findings

Fingerprints ignore line numbers, so moving code around does not resurface accepted findings. Every run also writes a Markdown table to the GitHub job summary (--summary).

GitHub Action

One line, no install step; the scanners come from PyPI:

permissions:
  contents: read
  security-events: write
steps:
  - uses: actions/checkout@v4
  - uses: Pyhroff/aisec-suite@v0.2.0
    with:
      fail-on: high

Inputs: path, fail-on, rag-dir, baseline, install, upload-sarif. Needs security-events: write for the upload step. Inputs reach the shell only through quoted env vars, never interpolated into script text.

(The action itself has not yet been run on GitHub Actions; the CLI and adapters are tested, including with fake scanners in CI.)

Honest scope

• Static extraction is best-effort. In a study of 90 public MCP repos it found tools in 53 (about 59%); "no tools found" prints a note and means unknown, not safe.
• Findings are heuristics for human review. In the same study only 37.5% (95% CI 24-53%) of mcpaudit v0.6's HIGH permission_scope findings were accurate, and none of the flagged repos had genuine tool poisoning. Use the patched scanners (mcpaudit 0.7 / memsentry 1.2) for fewer false positives; see mcp-scan-study/REPORT.md.
• mcpaudit's dynamic (live LLM) and rug-pull checks are not part of this suite; use mcpaudit directly for those.
• Line numbers for extracted tools point at the registration call, not the description text.

Development

pip install -e ".[dev]" && pytest -q (adapter tests use in-memory fake scanners and always run; a few end-to-end tests skip unless the real scanners are installed).
