Code Firewall Mcp

Overview

Code Firewall Mcp is a Model Context Protocol server that filters code through structural similarity analysis to prevent malicious patterns from reaching execution tools. It acts as a security layer between AI assistants and code execution, letting Claude and other MCP clients call it as a built-in tool rather than requiring manual copy-paste workflows.

The server runs locally on your machine via the Python package code-firewall-mcp, installed through uvx. It requires no credentials and works immediately after installation. Version v0.7.0 is published under the MIT license with full source code available at egoughnour/code-firewall-mcp on GitHub.

Code Firewall Mcp belongs in the Development category on mcp.site and works with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim the listing to verify ownership and keep information up to date.
