Implements a proxy-based architecture that intercepts all MCP tool calls and responses, analyzing them against signature-based detection rules before allowing execution. Operates as a transparent proxy layer between AI applications and their MCP servers, providing granular allow/block decisions per tool invocation. Supports Cursor, Claude, VS Code, and Windsurf through a unified desktop interface.
