📚 DocsFetcher MCP Server

An MCP server that fetches package documentation from multiple language ecosystems for LLMs like Claude without requiring API keys.

✨ Features

🚀 Installation

Claude Desktop

1. Open Claude Desktop → Settings → Developer
2. Click "Edit Config" and add:

{
  "mcpServers": {
    "docsFetcher": {
      "command": "npx",
      "args": [
        "-y",
        "@smithery/cli@latest",
        "run",
        "@cdugo/mcp-get-docs",
        "--config",
        "'{}'"
      ]
    }
  }
}

Cursor IDE Configuration

1. Open Cursor IDE → Settings → MCP -> Add New MCP Servier
2. Add:

    Name: docsFetcher
    Command: npx -y @smithery/cli@latest run @cdugo/mcp-get-docs --config "{}"

Prerequisites

- 📋 Node.js 18 or later

🏃‍♂️ Running Locally

git clone https://github.com/cdugo/package-documentation-mcp
cd package-documentation-mcp
npm install
