CARBON MCP

CARBON is an AI testing harness that integrates with coding agents to perform risk-based testing, exploratory checks, accessibility investigations, and generate evidence-backed reports. It coordinates 12 free testing commands to analyze project risk, reproduce bugs, and provide confidence scores without replacing existing test frameworks.
