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 — powered by local LLMs and any OpenAI-compatible provider. Free. Self-hostable. 6 languages.

Works With

Any AI tool that generates code — if it writes it, OCR reviews it.

What AI Linters Miss

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'`	❌ Miss
Stale APIs	Using deprecated APIs from training data	❌ Miss
Context window artifacts	Logic contradictions across files	❌ Miss
Over-engineered patterns	Unnecessary abstractions, dead code	❌ Miss
Security anti-patterns	Hardcoded example secrets, `eval()`	❌ Partial

Open Code Review detects all of them — across 6 languages, for free.

Deep Scan (L3) — How It Works

L3 combines three analysis layers for maximum coverage:

hljs language-sql

Layer 1: Structural Detection         Layer 2: Semantic Analysis        Layer 3: LLM Deep Scan
├── Hallucinated imports (npm/PyPI)   ├── Embedding similarity recall   ├── Cross-file coherence check
├── Stale API detection               ├── Risk scoring                  ├── Logic bug detection
├── Security patterns                 ├── Context window artifacts      ├── Confidence scoring
├── Over-engineering metrics          └── Enhanced severity ranking     └── AI-powered fix suggestions
└── A+ → F quality scoring

Powered by local LLMs or any OpenAI-compatible API. Run Ollama for 100% local analysis, or connect to any remote LLM provider — the interface is the same.

hljs language-bash

# Local analysis (Ollama)
ocr scan src/ --sla L3 --provider ollama --model qwen3-coder

# Any OpenAI-compatible provider
ocr scan src/ --sla L3 --provider openai-compatible \
  --api-base https://your-llm-endpoint/v1 --model your-model --api-key YOUR_KEY

AI Auto-Fix — `ocr heal`

Let AI automatically fix the issues it finds. Review changes before applying.

hljs language-bash

# Preview fixes without changing files
ocr heal src/ --dry-run

# Apply fixes + generate IDE rules
ocr heal src/ --provider ollama --model qwen3-coder --setup-ide

# Only generate IDE rules (Cursor, Copilot, Augment)
ocr setup src/

Multi-Language Detection

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

MCP Server — Use in Claude Desktop, Cursor, Windsurf

Integrate Open Code Review directly into your AI IDE via the Model Context Protocol:

hljs language-bash

npx @opencodereview/mcp-server

Claude Desktop (claude_desktop_config.json):

hljs language-json

{
  "mcpServers": {
    "open-code-review": {
      "command": "npx",
      "args": ["-y", "@opencodereview/mcp-server"]
    }
  }
}

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).

💡 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 — one inspects your running app, the other inspects your source code.
