Overview: What is Valyu MCP Server?

The Valyu MCP Server is a powerful tool designed to enable AI applications, such as Claude Desktop and other tools with MCP support, to access high-quality context from diverse data sources like Wikipedia articles, arXiv papers, and web searches. By leveraging the Model Context Protocol (MCP), this server acts as a bridge between your AI application and external data repositories, enhancing its capability to provide accurate and relevant information. This document will guide you through the setup, configuration, and usage of the Valyu MCP Server.

🔧 Core Features & MCP Capabilities

Valyu MCP Server integrates seamlessly with the Model Context Protocol (MCP), offering a robust set of features that significantly bolster AI application performance. The core capabilities include:

• Data Retrieval: Access to comprehensive information from sources such as Wikipedia, arXiv papers, and web search results.
• Prompt Augmentation: Enhances prompts by incorporating relevant context, ensuring more accurate and detailed outputs.
• User Authentication: Integrate with Valyu API for secure access using a unique API key.

⚙️ MCP Architecture & Protocol Implementation

The Valyu MCP Server is built to adhere strictly to the Model Context Protocol (MCP). This involves implementing the following components:

1. Command Interface: The server exposes a command-line interface that can be invoked by MCP clients.
2. Data Processing Modules: These modules handle data retrieval from various sources and format it for the AI application.

This diagram illustrates the flow of requests from an AI application through the MCP protocol to the Valyu MCP Server and eventually to the data source. The server processes the request, retrieves relevant context, and returns it via the MCP protocol.

🚀 Getting Started with Installation

Getting started with the Valyu MCP Server involves a few straightforward steps, ensuring you have all necessary components in place before deployment.

Option 1: Automated Setup (Recommended)

To quickly set up the server:

1. Clone the Repository:

   git clone https://github.com/ValyuNetwork/valyu-mcp.git
   cd valyu-mcp
   

2. Run the Setup Script:

   chmod +x setup.sh  
   ./setup.sh       
   

   The script will handle environment creation, dependency installation, and configuration prompts.

Option 2: Manual Setup

For environments where automated setup may not be ideal:

1. Clone the Repository:

   git clone https://github.com/ValyuNetwork/valyu-mcp.git
   cd valyu-mcp
   

2. Create a Virtual Environment and Activate It:

   python -m venv .venv
   source .venv/bin/activate    # macOS/Linux
   .venv\Scripts\activate      # Windows
   

3. Install Dependencies:

   pip install -r requirements.txt
   

4. Create a .env File for Configuration:

   echo "VALYU_API_KEY=your-api-key-here" > .env
   

5. Configure MCP Clients: Update your Claude Desktop config file to recognize the Valyu MCP Server.

💡 Key Use Cases in AI Workflows

The Valyu MCP Server supports a wide range of use cases, enhancing various AI workflows through precise integration with MCP clients:
