Code review as an MCP server. Connect it to Claude Code, Cursor, or any MCP-compatible AI assistant.

— Review any source code snippet for bugs, security, performance, and style`review_code`

— Review a git diff for potential issues before merging`review_diff`

— Review a local file by path`review_file`

Powered by the same methodology as our Code Review Agent: OWASP Top 10 scanning, N+1 query detection, race condition analysis, and structured output with severity ratings.

```
# Add to your Claude Code MCP config:
claude mcp add code-review -- uvx aicraft-code-review
```

Or add to your `~/.cursor/mcp.json`

or `claude_desktop_config.json`

:

```
{
  "mcpServers": {
    "code-review": {
      "command": "uvx",
      "args": ["mcp-code-review"]
    }
  }
}
pip install aicraft-code-review
python -m mcp_code_review
```

Once connected, ask your AI assistant:

"Review this Python code for security issues: [paste code]" "Review this diff before I commit: [paste diff]" "Review this file: /path/to/file.py"

The AI will call the MCP server and return structured results.
