AI code review for Python teams

Last updated 2 October 2026.

Does MergeSafe review Python code?

Yes: MergeSafe reviews Python pull requests like any other language, and can prove some Python logic bugs by running a short script in an isolated sandbox.

What Python teams get

• Bugs shown, not just claimed. When a pull request changes .py files, a review may run a short Python script in an isolated sandbox to show a logic bug is real.
• Security on every level. SQL, command and template injection, unsafe deserialization, path traversal, SSRF, secrets and access control. See Security checks.
• Lockfiles don’t count toward size. uv.lock, poetry.lock and generated files such as _pb2.py are left out of the large pull request count.
• Dependabot for uv. For a project with uv.lock, the recommendations suggest Dependabot’s uv ecosystem.
• Your conventions. Rules in AGENTS.md are applied to every review.

What it doesn’t do

• It doesn’t match your dependencies against vulnerability databases. Use Dependabot or a similar tool.
• It doesn’t run your test suite. Keep your CI.
