MCP Memory Gateway

MCP Memory Gateway (ThumbGate) is a local-first, pre-action firewall and PreToolUse engine for MCP-compatible AI coding agents (like Claude Code, Codex, Cursor, Gemini CLI, and more). It acts as an enforcement layer, evaluating tool calls before execution to prevent destructive or risky operations, like directory wipes or secret leaks, by blocking or warning on high-risk commands. Accepted operator feedback is locally stored, letting the firewall self-improve without retraining AI models. It’s for operators and teams building with coding agents that need to safeguard infrastructure and pipelines from costly agent-driven mistakes.
