These share tags the maintainers applied themselves, such as policy-engine, zero-trust, ai-guardrails, cline-ai. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
