Firewall

mcpwall (Firewall) is a transparent proxy for Model Context Protocol (MCP) servers, designed to enforce local, programmable security policies on developer tools and AI agents. It operates by intercepting all MCP tool requests and responses, blocking dangerous actions, redacting secrets, and denying prompt injection attempts, entirely without cloud or external dependencies. This tool is ideal for developers and organizations running AI and MCP tools who want runtime enforcement, compliance (GDPR/EU AI Act), and full data privacy by keeping all logic and logs local.
