📦 Supported Libraries

| Library | Documentation Site | | ------------------ | ------------------------------ | | 🦜 Langchain | python.langchain.com/docs | | 🦙 Llama-Index | docs.llamaindex.ai/en/stable | | 🤖 OpenAI | platform.openai.com/docs | | 📦 UV | docs.astral.sh/uv | | 🎯 Qubrid | docs.qubrid.com |

🛠️ Installation

Quick Start (Recommended - NPM)

The easiest way to use this MCP server is via npx:

npx -y webdocs-mcp-server

This requires:

• Node.js 16+ installed
• UV package manager (installation guide)

Manual Installation (For Development)

Prerequisites

• Python 3.10 or higher
• UV package manager

Setup

1. Clone the repository

   git clone <your-repo-url>
   cd Docu_MCP

2. Install dependencies

   uv sync

3. Set up environment variables

   Create a .env file in the project root:

   SERPER_API_KEY=your_serper_api_key_here
   GROQ_API_KEY=your_groq_api_key_here

🔑 API Keys Setup

1. Serper API Key (Required)

The Serper API is used for web search functionality.

1. Visit serper.dev
2. Sign up for a free account
3. Navigate to your dashboard
4. Copy your API key
5. Add it to your .env file

2. Groq API Key (Optional)

Currently reserved for future LLM integration features.

1. Visit console.groq.com
2. Sign up and get your API key
3. Add it to your .env file

🚀 Usage

Option 1: Using the MCP Client (Python)

Test the server directly with the included client:

uv run mcp_client.py

Example output:

Available Tools: ['get_docs']
[Documentation content with sources...]

You can customize the query in mcp_client.py:

query = "How to setup ComfyUI AI ML Template?"
library = "qubrid"
res = await session.call_tool(
    "get_docs",
    arguments={"user_query": query, "library": library}
)

Option 2: Using Claude Desktop

Step 1: Configure Claude Desktop

Open your Claude Desktop config file:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

🚀 Recommended: NPM Installation (Remote)

Add this configuration to use the published npm package:

{
  "mcpServers": {
    "WebDocs": {
      "command": "npx",
      "args": ["-y", "webdocs-mcp-server"],
      "env": {
        "SERPER_API_KEY": "your_serper_api_key_here",
        "GROQ_API_KEY": "your_groq_api_key_here"
      }
    }
  }
}

💻 Alternative: Local Development

If you're developing locally, use this configuration:

{
  "mcpServers": {
    "WebDocs": {
      "command": "C:\\Users\\YOUR_USERNAME\\.local\\bin\\uv.EXE",
      "args": ["--directory", "D:\\Path\\To\\Docu_MCP", "run", "mcp_server.py"],
      "env": {
        "SERPER_API_KEY": "your_serper_api_key_here",
        "GROQ_API_KEY": "your_groq_api_key_here"
      }
    }
  }
}

⚠️ Important:

• For NPM method: Just add your API keys
• For local method: Replace YOUR_USERNAME and D:\\Path\\To\\Docu_MCP with your actual paths!

Step 2: Restart Claude Desktop

1. Completely close Claude Desktop
2. Reopen Claude Desktop
3. The WebDocs tool should now be available

Step 3: Use the Tool

In Claude Desktop, you can ask:

"Use the WebDocs tool to search for how to create a ReAct agent in Langchain"

Claude will automatically call the get_docs tool with the appropriate parameters.

Option 3: Using MCP Inspector (Debugging)

The MCP Inspector is a powerful tool for testing and debugging your MCP server.

Start the Inspector

npx @modelcontextprotocol/inspector uv --directory "D:\AbhiiiMan Codes\Docu_MCP" run mcp_server.py

This will:

1. Start the MCP server
2. Launch a web interface at http://localhost:5173
3. Allow you to interactively test the server

Using the Inspector

1. Open your browser to the provided URL
2. Click "Connect" to establish connection
3. Navigate to "Tools" tab
4. Select get_docs tool
5. Fill in the parameters:
   • user_query: Your search query
   • library: One of langchain, llama-index, openai, uv, or qubrid
6. Click "Run Tool" to test

Troubleshooting

If port is already in use:

# Find and kill the process using port 6277
netstat -ano | findstr :6277
taskkill /PID <process_id> /F

🔧 Available Tools

get_docs

Searches and retrieves documentation content from supported libraries.

Parameters:

• user_query (string, required): The search query
  • Example: "How to use Langchain with OpenAI"
• library (string, required): The library to search
  • Options: langchain, llama-index, openai, uv, qubrid

Returns:

• Text content from documentation with source URLs

Example:

await session.call_tool(
    "get_docs",
    arguments={
        "user_query": "vector store integration",
        "library": "langchain"
    }
)

🔍 How It Works

graph LR
    A[User Query] --> B[MCP Server]
    B --> C[Serper API]
    C --> D[Google Search]
    D --> E[Documentation URLs]
    E --> F[Fetch Content]
    F --> G[Clean HTML]
    G --> H[Return Text]
    H --> I[User/Claude]

1. Query Construction: Combines library domain with user query
2. Web Search: Uses Serper API to search Google
3. Content Fetching: Retrieves raw HTML from documentation pages
4. Content Cleaning: Extracts readable text using Trafilatura
5. Response Formation: Formats content with source attribution

🐛 Debugging & Testing

Test Server Launch

Run the test script to verify configuration:

uv run test_server.py

Expected output:

✅ Server process started successfully!
✅ Server is running and accepting connections!

Common Issues

| Issue | Solution | | ----------------------------- | ----------------------------------------------- | | 🔴 PORT IS IN USE | Kill process on port 6277 or use different port | | 🔴 SERPER_API_KEY not found | Check .env file exists and contains valid key | | 🔴 program not found | Use full path to uv.EXE in Claude config |

Enable Debug Logging

Add to your .env:

LOG_LEVEL=DEBUG
