Coverctl

Coverctl is an open-source, local-first code coverage governance tool designed specifically for AI coding agents. By integrating directly with AI agents and the Model Context Protocol (MCP), it enforces test coverage policy at the 'agent loop' level—before code is committed—catching regressions instantly rather than post-commit via CI dashboards. Ideal for Go, Python, JavaScript, Java, and Rust projects, Coverctl brings polyglot coverage enforcement, detailed analytics, and robust security to any MCP-capable agent or traditional CLI workflow.
