Code Firewall Mcp

Code Firewall Mcp is an open-source MCP (Model Context Protocol) server that acts as a structural similarity-based code security filter for AI code tools and agents. It parses, normalizes, embeds, and compares code files or strings against a blacklist of dangerous patterns, blocking potentially malicious code from being passed to execution tools. It integrates with Ollama for embeddings, ChromaDB as a vector database, Claude Desktop, and is compatible with Python tools and the broader MCP ecosystem. This server is valuable for developers, security engineers, and anyone running or deploying AI code generation/execution pipelines, offering programmatic tools to check, blacklist, record, and manage code patterns.
