ThumbGate

Self-improving pre-action firewall that blocks risky tool calls from AI coding agents.

Pluginfreemium

ThumbGate is a local-first pre-action firewall that intercepts an AI coding agent's proposed tool call before it runs, hard-blocking detected secret leaks and warning on high-risk commands like rm -rf or force-push. Accepted feedback becomes reusable local lessons, and repeated failures can be promoted into hard prevention rules, working across Claude Code, Cursor, Codex, and other MCP-compatible agents.
