CI failures
your agent
can fix.

Track every GitHub Actions and Checks failure on faultline.live. Wire your coding agent in via MCP and have it diagnose, patch, and resolve from your editor. When you want hands-off, add Gas Town for autonomous fixers that run on their own.

GitHub-native ingest

Install the Faultline GitHub App on any repo and every workflow_run / check_run failure becomes a tracked issue. SDK ingest still works for runtime errors, but you can start CI-only.

MCP-driven fixes

Drop the Faultline MCP server into Claude Code, Cursor, or Windsurf. Your agent lists issues, fetches stack traces, writes a fix, opens a PR, and marks it resolved — all without leaving your editor.

Version-controlled storage

Powered by Dolt — MySQL-compatible with git semantics. Time-travel any issue to any past commit. Full audit trail of every fix. Batch commits every 60 seconds.

Two paths to a green build.

Start light with MCP + your editor. Ramp up to autonomous polecats when you're ready. Both share the same data plane — switching is config, not migration.

Solo · MCP

You + your coding agent

Best when you're the one driving fixes and you want a tight loop with the agent in your editor.

  • Faultline GitHub App posts CI failures to faultline.live
  • MCP server in Cursor / Claude Code / Windsurf reads issues
  • Agent diagnoses, writes fix, opens PR, calls mark_resolved
  • You stay in the loop for review and merge
Hands-off · Gas Town

Polecats fix it for you

Add Gas Town when you want fixes to run without you in front of an editor — overnight, off-hours, or just at scale.

  • Faultline files a bead in your target Gas Town rig
  • A polecat — agent process — claims the bead and works it
  • Refinery merges the fix; the bead closes
  • 10-min quiet period verifies the fix held

Minimal stack. Maximum control.

One binary. One Dolt server. No Redis, Kafka, or ClickHouse required.
