Verdict

Pick Context7 MCP Server if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Pick ROS MCP Server if you want zero-setup with no API key, and you need the broadest set of tools.

Add Context7 MCP Server

Install / run

npx -y @upstash/context7-mcp

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "context7-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@upstash/context7-mcp"
      ],
      "env": {
        "CONTEXT7_API_KEY": "<optional-your-context7-api-key>"
      }
    }
  }
}

Add ROS MCP Server

Install / run

claude mcp add ros-mcp -- uvx ros-mcp --transport=stdio

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "ros-mcp-server": {
      "command": "uvx",
      "args": [
        "ros-mcp",
        "--transport=stdio"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.
