MCP-connected runtime QA maps critical flows and entry points, then re-tests the blast radius of each Claude Code/Cursor/Codex change against live Postgres/Kafka/APIs/MCP tools—contracts, authz, OWASP, errors—before merge, with self-heal when behavior changes on purpose.
Functionize ships an MCP server so Claude Code/Cursor/Copilot hand change context to Studio, which builds/runs smoke or regression suites against the live app and returns the first failing step in-chat—closing the gap where agents never saw the product run.
