• Chaos-MCP

  by AraneaDev · Free · github

  Chaos-MCP is an MCP stdio server that runs isolated mutation testing against a target codebase to expose gaps in its test suite. It wraps four language engines — StrykerJS (TS/JS), cosmic-ray (Python), cargo-mutants (Rust), Infection (PHP) — and exposes three tools: audit_code_resilience, triage_test_coverage, and estimate_audit.
