# BugLens

> AI code review for GitHub pull requests. Reviews every PR against your own codebase's context — 8 deterministic rules plus AI analysis — and exposes the same review capability to AI coding agents via REST API, MCP server, and CLI.

## For AI coding agents

- [For Agents](https://buglens.app/for-agents/): How agents like Devin, Claude Code, GitHub Copilot, Cursor, Windsurf, and Cline integrate BugLens as an automated review/merge gate.
- API: `POST https://buglens.app/api/v1/review` — submit a diff for review, returns machine-readable JSON findings.
- MCP Server: `https://mcp.buglens.app`
- API keys: generate one at `https://buglens.app/settings` after installing the GitHub App.
