You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Local-first backend developer workspace exposing API debugging, SSH, database, workspace, and diagnostics tools to AI agents through a local MCP server, with workspace-scoped safety policies and confirmation for risky actions.
Probes your live API and classifies why each endpoint failed (root cause + evidence + calibrated confidence) over MCP, so your AI assistant debugs from evidence instead of guessing. Deterministic rules, no black box. Works with FastAPI, Express, Next.js, tRPC, and GraphQL. npm i -g qa-probe
