ThumbGate

Overview

ThumbGate is a Model Context Protocol (MCP) server: Pre-action gates that block AI agents from repeating known mistakes. In practice that means any MCP-compatible AI assistant can call ThumbGate's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package thumbgate speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.27.17, published under the MIT license, with source at IgorGanapolsky/ThumbGate on GitHub, where it has earned 26 stars.

ThumbGate is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
