FAQ

Does Ranex send my code to the cloud?

Ranex is designed as a local-first tool. It indexes your project locally.

What is the difference between CLI, Python API, and MCP?

• CLI: human-friendly entrypoint for scanning and querying.
• Python API: programmatic access from Python scripts/tests.
• MCP: integration layer for AI assistants via a local MCP server.

Do I need to run scan every time?

Run ranex atlas scan whenever:

• you changed many files
• you switched branches
• Atlas results appear stale

Where is the Atlas database stored?

• .ranex/atlas.sqlite

How do I reset Ranex for a project?

• Delete .ranex/atlas.sqlite and re-run ranex atlas scan.

How do I allow a new dependency?

• Add it to .ranex/firewall.yaml under allowed_packages.

Why does the firewall block standard library modules?

Your policy can explicitly block patterns even if they are part of the standard library. This is intentional when a module/pattern is considered unsafe in your environment.
