Introduction to Firebreak
STARTFirebreak is an automated incident mitigation and verified rollback platform engineered for teams deploying web applications on Vercel and source code on GitHub. Powered by the NitroStack Model Context Protocol (MCP) framework.
The Problem Firebreak Solves
When a bad commit crashes production after a deployment, teams face a chaotic 45-minute fire drill. Monitoring alerts only point out the symptom (e.g. 500 error spike), forcing on-call engineers to manually inspect commits, guess the culprit, and hesitate over rollbacks for fear of breaking database state or reverting unrelated releases.
Firebreak transforms this manual diagnostic loop into a mathematically verified 55-second recovery cycle with full auditability.
The 6-Step Closed-Loop Lifecycle
Firebreak operates as a deterministic finite-state machine across six discrete phases:
| Step | Name | Responsibility |
|---|---|---|
| 1 | DETECT | Ingests alerts via HMAC SHA-256 signed webhooks. Deduplicates against a 15-minute sliding fingerprint window. |
| 2 | TRACE | Matches broken vs. last-known-good deployments. Runs an 8-factor commit blame scorer (+40 file match, +30 hunk, +25 symbol). |
| 3 | PROPOSE | Runs 6 preflight safety gates (target readiness, drift check, uniqueness). Stages a rollback with a 15-min TTL. |
| 4 | APPROVE | Enforces human-in-the-loop authorization via a 1,500ms Hold-to-Confirm web button or authenticated MCP tool call. |
| 5 | EXECUTE | Rolls back production on Vercel atomically with an intelligent promote fallback that works across all Vercel tiers. |
| 6 | VERIFY | Polls the service's health URL every 10s until three consecutive 200 OK responses confirm full recovery. |
The 6-Step Incident Lifecycle State Machine
Native Model Context Protocol (MCP)
Rather than building a simple read-only dashboard or conversational chatbot, Firebreak exposes its full operational capability as an official Model Context Protocol server. AI agents (Claude Desktop, Cursor, ChatGPT) can list active incidents, inspect suspect commits with code diffs, and stage rollback proposals directly in their chat interface.
