Linebreak Gate: Read-only MCP server serves approved specs to coding agents
vladimir_linebreak · reddit · 2026-08-29
To address the issue where agents build what they understood rather than what was approved, the developer released Linebreak Gate. This tool uses Git as a transport layer to record user acceptance criteria in the repository and serves them to Claude Code, Cursor, or Codex via the Model Context Protocol (MCP) in a read-only manner.
Core Features:
- Read-only MCP Server: Provides six tools (list/get/next story, per-story checks using the same engine as CI, spec/signature status). Agents cannot edit approved criteria via any calls.
- Workflow Integration: Land criteria with linebreak-gate spec approve and connect to editors via linebreak-gate mcp.
- Serverless/Keyless: Local-first approach with no account or API key required. Installed via uv tool install linebreak-gate.
- Bonus: Includes a free fail-closed CVE gate for CI. A paid tier ($99/mo/team) offers cryptographic signing and tamper evidence.
The tool aims to solve the problem of spec drift where documentation (Notion/Docs) disconnects from actual development during the week.
