MCP SERVER

MCP Feedback Enhanced

by Minidoracat ↗

Let an agent stop and ask you before it carries on, with your written reply coming back as the tool result.

Summary
The agent asks at the point where it would otherwise pick an interpretation.

What it takes off you is the correction afterwards: the model hands you its summary while the work is still open, and your answer arrives as a tool result. Worth checking your client first — MCP now has native elicitation and interactive tool UIs, and if those cover the checkpoint you want, you do not need this.

What it is

A two-call server that puts a person in the loop. The feedback call posts the agent's own summary of what it has done against a project directory, then waits for your reply or for the timeout you set. The reply surface is either a browser page or a native desktop application, so it works locally, over SSH and inside WSL.

What you get
  • A feedback prompt the agent raises mid-task, carrying its summary of the work and the project directory it applies to (`interactive_feedback`)
  • A timeout on that prompt, so an unanswered request returns instead of holding the run open
  • Text, saved prompts and uploaded images as the reply — images come back as standard MCP image content
  • Two interfaces with the same functionality: a Tauri desktop application on Windows, macOS and Linux, or a browser page that needs no GUI on the machine — which is what makes it work over SSH and in WSL
  • Session history and statistics recorded as the conversation goes
  • The system and environment details of the machine the server runs on, returned as JSON (`get_system_info`)
Requirements

Uvx on your PATH, and someone at the keyboard — the feedback call waits for an answer, and what it returns is whatever you type. Run `uvx mcp-feedback-enhanced@latest` and stay on v2.6.1 or newer: that release removed the command-execution feature behind an unauthenticated WebSocket, and started validating `Origin` before accepting a connection so a web page you visit cannot reach the local `/ws`. The Web UI and its WebSocket endpoint still have no authentication of their own, so leave `MCP_WEB_HOST` at `127.0.0.1` and use SSH port forwarding for remote work rather than binding `0.0.0.0`. `MCP_WEB_PORT` defaults to 8765, `MCP_DESKTOP_MODE` switches to the desktop application, and `MCP_LANGUAGE` forces English, Traditional or Simplified Chinese.

Setup effort

One command — uvx mcp-feedback-enhanced@latest
