Human In The Loop MCP Server

Human in the loop mcp server lets Claude, Cursor and other MCP clients work with Human In The Loop directly. An MCP (Model Context Protocol) server that allows AI assistants to ask questions to humans via Discord.

What Human In The Loop does

An MCP (Model Context Protocol) server that allows AI assistants to ask questions to humans via Discord.

This MCP server is used when AI assistants need human input or judgment during their work. For example:

Tools it exposes

Once connected, the assistant can call this tool directly:

• Usage — AI assistants can ask questions to humans using the ask_human tool:

Installing the human in the loop mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Configuration

Before the server will start you need to supply one environment variable: DISCORD_TOKEN. Keep credentials in your client's env block or a secrets manager rather than committing them.

Requirements

• Rust (1.70 or higher) - Discord account and bot - MCP-compatible AI client (Claude Desktop, Copilot Edits, etc.)

Where it fits

Communication servers earn their keep on volume — summarising channels and threads that would otherwise cost you an hour of scrollback. Human In The Loop sits in that group, and the shape of its toolset — Usage — tells you what it is really for. Worth comparing against the other communication servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

• This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
• It will not start until its required credentials are present, so set those before wondering why the tools never appear.
• Maintained by KOBA789, written in Go.
• MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the human in the loop mcp server actually does with your data.
• Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
