MCP server and CLI for finding AI-generated code defects across six programming languages.
Copy the AI prompt to install this server into Claude Code, Cursor, or another agent โ or use 1-click editor setup below.
We haven't yet run this listing's install command through our automated sandbox check. This isn't a red flag โ we're steadily working through the catalog.
๐ก Paste the JSON block into your client's configuration file under mcpServers, then restart the application.
Inspect callable tools, capabilities, and parameters exposed to AI agents by Open Code Review.
The first open-source CI/CD quality gate built specifically for AI-generated code. Detects hallucinated imports, stale APIs, over-engineering, and security anti-patterns โ powered by local LLMs and any OpenAI-compatible provider. Free. Self-hostable. 6 languages.

Any AI tool that generates code โ if it writes it, OCR reviews it.
AI coding assistants (Copilot, Cursor, Claude) generate code with defects that traditional tools miss entirely:
| Defect | Example | ESLint / SonarQube |
|---|---|---|
| Hallucinated imports | import { x } from 'non-existent-pkg' | โ Miss |
| Stale APIs | Using deprecated APIs from training data | โ Miss |
| Context window artifacts | Logic contradictions across files | โ Miss |
| Over-engineered patterns | Unnecessary abstractions, dead code | โ Miss |
| Security anti-patterns | Hardcoded example secrets, eval() | โ Partial |
Open Code Review detects all of them โ across 6 languages, for free.

L3 combines three analysis layers for maximum coverage:
Powered by local LLMs or any OpenAI-compatible API. Run Ollama for 100% local analysis, or connect to any remote LLM provider โ the interface is the same.

Language-specific detectors for 6 languages, plus hallucinated package databases (npm, PyPI, Maven, Go modules):
| Language | Specific Detectors |
|---|---|
| TypeScript / JavaScript | Hallucinated imports (npm), stale APIs, over-engineering |
| Python | Bare except, eval(), mutable default args, hallucinated imports (PyPI) |
| Java | System.out.println leaks, deprecated Date/Calendar, hallucinated imports (Maven) |
| Go | Unhandled errors, deprecated ioutil, panic in library code |
| Kotlin | !! abuse, println leaks, null-safety anti-patterns |
| Open Code Review | Claude Code Review | CodeRabbit | GitHub Copilot | |

Integrate Open Code Review directly into your AI IDE via the Model Context Protocol:
Claude Desktop (claude_desktop_config.json):
Cursor / Windsurf / VS Code Copilot: Add the same configuration in your MCP settings.
Available MCP Tools: ocr_scan (quality gate scan), ocr_heal (AI auto-fix), ocr_explain (issue explanation).
๐ก Chrome DevTools MCP Compatible: The OCR MCP Server follows the standard Model Context Protocol. Pair it with Google's Chrome DevTools MCP Server for a complete AI-native dev workflow โ one inspects your running app, the other inspects your source code.
