Rlhf Feedback Loop MCP server exists for a simple reason — assistants are far more useful when they can act on Rlhf Feedback Loop directly instead of describing what you should do. ThumbGate Pre-Action Checks self-improve from ranked lessons and repeated failures, hard-block detected secret leaks, and block matches in strict mode.
ThumbGate is the local-first Pre-Action Checks engine for AI coding agents. It runs in the PreToolUse hook on your machine: it evaluates a proposed tool call and logs the decision before tool execution. It hard-blocks detected secret leaks and two direct self-disable command classes by default — commands that terminate the ThumbGate gate process or enable its bypass environment override. Other high-risk classes, including destructive deletes (rm -rf), force-push, fetch-and-run, direct guardrail-file edits, off-scope edits, and deploys, warn and log by default.

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need one environment variable: THUMBGATE_HUMAN_REVIEWER_ID. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by igorganapolsky; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Rlhf Feedback Loop's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
