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.

The A–E grade is our heuristic synthesis — a "review this" prompt, not a verdict. Each factor is tagged by what backs it: attested (a verifiable record), reported (a third party's claim), or inferred (our own heuristic, e.g. permissions). See methodology.

No known CVEs for this server.
No tool-safety findings — heuristic detectors run on the compute-risk cadence; a finding appears when a tool trips a rule.
[](https://mcpobservatory.com/servers/github:AraneaDev/Chaos-MCP/security) Heuristic, inferred signals — false positives (legitimately powerful tools, forks, language ports) are expected. Treat each as "review this", not a verdict. See the ecosystem-wide picture on the security hub, or the fleet security of AraneaDev.
