Kerno: local runtime QA that verifies agent changes against your stack
At a glance
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. This workflow is listed under MCP, QA, runtime-testing, coding-agents, monetization-adjacent.
Agents / tools
Kerno, Claude Code, Cursor, Codex, GitHub Copilot, MCP
MCP server plus local hooks route agent-written commits, PR text, emails and support replies into one editable queue; you rewrite and approve, then the agent sends exactly your version—Claude Code tested; Codex/Gemini/Copilot/Cursor installer-configured; free tier then paid.
Open-source local procedural memory that learns only after tests pass, then hands Claude Code/Codex/Cursor a short verified skill note on similar tasks (reported token/tool cuts in published benchmarks).
SuperCompress v2 compresses context against the query (keeps answer-critical lines verbatim): ~64% mean cut on their B5 coding-agent suite with 24/24 evidence-retention passes; MCP/plugin for Cursor/Claude Code/Codex plus hosted API and open weights.
