MCP Code Review Server – AI code review in your editor

A new open-source MCP Code Review Server from AICraft enables AI-powered code review inside editors like Claude Code and Cursor, scanning for bugs, security flaws, performance issues, and style problems using OWASP Top 10, N+1 query detection, and race condition analysis. The tool, available under an MIT license, requires Python 3.11+ and an MCP-compatible client, and returns structured results with severity ratings.

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.
