Two-Step Plan MCP

I wanted to try the approach in this tweet so Claude wrote this code. https://x.com/JohnONolan/status/1942889686646521900

How it Works

This MCP server provides a tool that:

1. Uses Claude CLI to create an initial detailed plan for a given task
2. Has a second Claude CLI instance critique the plan and provide an improved version
3. Uses a third Claude CLI instance to read both plans, choose the better one, and delete the other
4. Returns the file path to the selected plan

Install MCP

{
  "mcpServers": {
    "two-step-plan": {
      "command": "npx",
      "args": ["-y", "two-step-plan"]
    }
  }
}

Requirements

• Node.js v18 or higher
• Claude Code tool installed and configured

Using the Standalone Plan Tool

You can use the plan tool directly without setting up the MCP server:

1. Install globally:

npm install -g two-step-plan

2. Run the tool:

claude-plan "Your task description here"

For example:

claude-plan "Design a REST API for a task management system"

Development

Run in development mode with auto-reload and MCP inspector:

npm run dev

Build the project:

npm run build

Watch for changes and rebuild:

npm run watch

Inspect the MCP server:

npm run inspect
