[stex2005]

Overview

Add comprehensive documentation covering installation, tutorial, and usage of ros-mcp installed through pip, including:

Installation

• Instructions for installing ros-mcp using pip:

  pip install .

Usage

• Example command to run ros-mcp with HTTP transport:

  ros-mcp --transport=http

Integration with LLM client

• Document integration steps using mcp.json configuration for connecting LLM clients.
• Provide example and explanation for configuring and using the LLM client with ros-mcp through mcp.json.

"ros-mcp-server-pip": {
      "name": "ROS-MCP Server (pip)",
      "transport": "stdio",
      "command": "wsl",
      "args": [
        "-d", "Ubuntu",
        "bash", "-l", "-c", "cd /mnt/c/Users/sd37989/ros-mcp-server && ros-mcp --transport=stdio"
      ]
    }

Needs the -l, which loads the full environment, finds ros-mcp
Needs cd to local path to have access to utils folder

@rjohn-v this is somewhat an urgent issue as there is no docs on how to install/use pip install
