About

MaruCheck is a local-first CLI that verifies AI-generated code changes against human-owned "Quality Contracts" the coding agent cannot edit, catching cases where a green test suite hides silently altered behavior (like a quota exploit). It runs deterministic risk scoring, mutation testing, and semantic drift detection, and exposes an MCP server so an agent can request—but not grant—its own verification verdict.

What it can do

  • Verify AI-generated code diffs against versioned Quality Contracts

    Code diff → Verification verdict

  • Run deterministic risk scoring on code changes

    Code diff → Risk score

  • Perform mutation testing on code changes

    Code diff → Mutation test results

  • Detect semantic drift between code behavior and approved behavior

    Code diff → Drift report

  • Expose an MCP server allowing an agent to request a verification verdict without granting it

    MCP request → Verification verdict

  • Block changes that pass tests but violate approved behavior

    Code diff and Quality Contract → Pass/block decision
