Security

• Never commit real credentials to git.

• .env and .env.* are gitignored; only .env.example is tracked.

• Keep secrets in environment variables or secret managers.

• Rotate credentials immediately if accidentally exposed.

• CI and release workflows run secret scanning with OSS gitleaks (no GITLEAKS_LICENSE secret required).

Testing

uv sync --extra dev
python3 -m pytest
python3 -m compileall src
uv build

Release automation (GitHub + PyPI)

• CI workflow: .github/workflows/ci.yml

• Release workflow: .github/workflows/release.yml

• Tag push (v*) triggers:

1. tests + compile + build + twine check

2. publish to PyPI via Trusted Publishing (OIDC)

3. GitHub Release creation with built artifacts

PyPI Trusted Publishing (one-time)

In the PyPI project flin-google-keyword-planner-mcp, add a Trusted Publisher:
