Deployments

The frontend is deployed on Vercel. The Flask backend ships as a Docker container (gunicorn with gevent, RQ workers under supervisord) on a free Hugging Face Space, with Supabase for PostgreSQL and Upstash for Redis. The Space was flagged twice for browser automation and the image is now browser-free. Its readiness endpoint reported the database, Redis and schema ready on 14 Oct 2026, and CI gates the deploy. Throughput under load has not been measured.

Published as agentbrake (v1.0.0, February 2026) on npm and as a Docker Hub image. It wraps an MCP server over stdio and applies allow/block policies and regex argument filtering. The published v1.0.0 predates the Sep 2026 fixes (fail-closed parsing and config, a working circuit breaker), which are on the main branch but not yet released. Human approval is not implemented.
