This is an MCP server designed to enhance interaction between users and agentic LLM tools by allowing the LLM to request feedback without interrupting its workflow.

User input MCP server

This is an MCP server that is intended to increase interaction between a user and an agentic LLM tool by giving the LLM the option to ask for feedback without stopping its train of thought.

It has two primary use cases:

  1. Asking the user to test a feature and provide feedback. For example:

    • Asking the user to observe and test a UI.
    • Asking the user to test a tool with a sensitive API key.
    • Asking the user to build and flash an embedded program and report behavior.

  2. Waiting for approval from the user before continuing implementation. For example:

    • The user could require manual approval of each feature before continuing implementation. This is important for keeping development on track, instead of wasting time and resources on a slightly wrong application.
    • The user could ask for an additional feature set before continuing with a prior plan.
    • The user could ask the agent to use a different API before getting further entrenched in a specific ecosystem.
    • The user could ask the agent to switch to a different set of libraries, framework, or language.

Installation

Download Pre-built Binaries

Download the latest release for your platform from the page:

  • Windows: prompt-mcp-windows-amd64.exe or prompt-mcp-windows-arm64.exe
  • Linux: prompt-mcp-linux-amd64 or prompt-mcp-linux-arm64
  • macOS: prompt-mcp-darwin-amd64 or prompt-mcp-darwin-arm64

    • Given macOS's security constraints, you will have to

      a. Make the executable runnable (chmod +x <executable name>)

      b. Allow the binary to run through settings > privacy > security

    • Basically, it might be a little easier to just build and run it yourself. up to you tho

Run the binary:

# Linux/macOS
./prompt-mcp-* serve

# Windows (PowerShell)
.\prompt-mcp-*.exe serve

Build from Source

Requirements: Go 1.21+

git clone <repository-url>
cd prompt-mcp
make all
./bin/prompt-mcp serve

Usage

To install in claude code, run

claude mcp add -s user prompt-user /full/path/to/prompt-mcp* -- serve

The server supports two input methods:

TTY Method (Terminal)

echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"user_input","arguments":{"prompt":"Enter your name:","method":"tty"}}}' | ./prompt-mcp serve

Web Method (Browser)

echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"user_input","arguments":{"prompt":"Enter your name:","method":"web"}}}' | ./prompt-mcp serve

The web method automatically opens your browser to a simple input form and works well with Claude Code and other environments where stdin/stdout are redirected.
