Interactive Mcp

What is Interactive Mcp about?

Interactive Mcp provides a local, cross‑platform MCP server that lets large language models interact directly with the end‑user’s operating system. It exposes a set of tools—such as prompting for user input, sending completion notifications, and running intensive chat sessions—so the model can request clarification, confirm actions, or gather feedback in real time.

How to use Interactive Mcp?

1. Install the server via npx (or run it from source).
2. Configure your MCP client (Claude Desktop, Cursor, VS Code, etc.) by adding a minimal JSON snippet that points to the interactive-mcp package.
3. Run the server (pnpm start for development or npx -y interactive-mcp for production).
4. The client can now call the exposed tools via the Model Context Protocol.

Key features of Interactive Mcp

• request_user_input: Prompt the user with a question and optional predefined choices.
• message_complete_notification: Send a simple OS notification when a task finishes.
• start_intensive_chat: Open a persistent terminal‑based chat session.
• ask_intensive_chat: Query the user within an active intensive chat.
• stop_intensive_chat: Close the intensive chat session.
• Configurable timeout (default 30 s) and ability to disable specific tools via command‑line flags.

Use cases of Interactive Mcp

• Interactive setup or configuration wizards driven by an LLM.
• Real‑time feedback collection during code generation or refactoring.
• Confirmation dialogs for potentially destructive actions in pair‑programming.
• Any workflow where a local AI assistant must verify intent before proceeding.

FAQ from the Interactive Mcp

Q: Do I need to install Node.js globally? A: Yes, Node.js (compatible version as defined in package.json) is required. The server runs via npx which handles package fetching.

Q: Can I disable certain tools? A: Use the --disable-tools (-d) flag with a comma‑separated list (e.g., -d message_complete_notification,intensive_chat).

Q: How do I change the input timeout? A: Pass --timeout (-t) followed by the number of seconds (e.g., -t 45).

Q: Is the server safe to run on my machine? A: The server only exposes the defined MCP tools and runs locally. It does not execute arbitrary commands unless explicitly invoked through the intensive chat tool.

Q: Where can I find the source code? A: On GitHub at https://github.com/ttommyth/interactive-mcp.

interactive-mcp

A MCP Server implemented in Node.js/TypeScript, facilitating interactive communication between LLMs and users. Note: This server is designed to run locally alongside the MCP client (e.g., Claude Desktop, VS Code), as it needs direct access to the user's operating system to display notifications and command-line prompts.

(Note: This project is in its early stages.)

Tools

This server exposes the following tools via the Model Context Protocol (MCP):

• request_user_input: Asks the user a question and returns their answer. Can display predefined options.
• message_complete_notification: Sends a simple OS notification.
• start_intensive_chat: Initiates a persistent command-line chat session.
• ask_intensive_chat: Asks a question within an active intensive chat session.
• stop_intensive_chat: Closes an active intensive chat session.

Usage Scenarios

This server is ideal for scenarios where an LLM needs to interact directly with the user on their local machine, such as:

• Interactive setup or configuration processes.
• Gathering feedback during code generation or modification.
• Clarifying instructions or confirming actions in pair programming.
• Any workflow requiring user input or confirmation during LLM operation.

Client Configuration

This section explains how to configure MCP clients to use the interactive-mcp server.

By default, user prompts will time out after 30 seconds. You can customize server options like timeout or disabled tools by adding command-line flags directly to the args array when configuring your client.

Please make sure you have the npx command available.

Usage with Claude Desktop / Cursor

Add the following minimal configuration to your claude_desktop_config.json (Claude Desktop) or mcp.json (Cursor):

{
  "mcpServers": {
    "interactive": {
      "command": "npx",
      "args": ["-y", "interactive-mcp"]
    }
  }
}

With specific version

{
  "mcpServers": {
    "interactive": {
      "command": "npx",
      "args": ["-y", "interactive-mcp@1.9.0"]
    }
  }
}

Example with Custom Timeout (30s):

{
  "mcpServers": {
    "interactive": {
      "command": "npx",
      "args": ["-y", "interactive-mcp", "-t", "30"]
    }
  }
}

Usage with VS Code

Add the following minimal configuration to your User Settings (JSON) file or .vscode/mcp.json:

{
  "mcp": {
    "servers": {
      "interactive-mcp": {
        "command": "npx",
        "args": ["-y", "interactive-mcp"]
      }
    }
  }
}

macOS Recommendations

For a smoother experience on macOS using the default Terminal.app, consider this profile setting:

• (Shell Tab): Under "When the shell exits" (Terminal > Settings > Profiles > [Your Profile] > Shell), select "Close if the shell exited cleanly" or "Close the window". This helps manage windows when the MCP server starts and stops.

Development Setup

This section is primarily for developers looking to modify or contribute to the server. If you just want to use the server with an MCP client, see the "Client Configuration" section above.

Prerequisites

• Node.js: Check package.json for version compatibility.
• pnpm: Used for package management. Install via npm install -g pnpm after installing Node.js.

Installation (Developers)

1. Clone the repository:

   git clone https://github.com/ttommyth/interactive-mcp.git
   cd interactive-mcp
   

2. Install dependencies:

   pnpm install
   

Running the Application (Developers)

pnpm start

Command-Line Options

The interactive-mcp server accepts the following command-line options. These should typically be configured in your MCP client's JSON settings by adding them directly to the args array (see "Client Configuration" examples).

Option	Alias	Description
--timeout	-t	Sets the default timeout (in seconds) for user input prompts. Defaults to 30 seconds.
--disable-tools	-d	Disables specific tools or groups (comma-separated list). Prevents the server from advertising or registering them. Options: request_user_input, message_complete_notification, intensive_chat.

Example: Setting multiple options in the client config args array:

// Example combining options in client config's "args":
"args": [
  "-y", "interactive-mcp",
  "-t", "30", // Set timeout to 30 seconds
  "--disable-tools", "message_complete_notification,intensive_chat" // Disable notifications and intensive chat
]

Development Commands

• Build: pnpm build
• Lint: pnpm lint
• Format: pnpm format

Guiding Principles for Interaction

When interacting with this MCP server (e.g., as an LLM client), please adhere to the following principles to ensure clarity and reduce unexpected changes:

• Prioritize Interaction: Utilize the provided MCP tools (request_user_input, start_intensive_chat, etc.) frequently to engage with the user.
• Seek Clarification: If requirements, instructions, or context are unclear, always ask clarifying questions before proceeding. Do not make assumptions.
• Confirm Actions: Before performing significant actions (like modifying files, running complex commands, or making architectural decisions), confirm the plan with the user.
• Provide Options: Whenever possible, present the user with predefined options through the MCP tools to facilitate quick decisions.

You can provide these instructions to an LLM client like this:

# Interaction

- Please use the interactive MCP tools
- Please provide options to interactive MCP if possible

# Reduce Unexpected Changes

- Do not make assumption.
- Ask more questions before executing, until you think the requirement is clear enough.
