Developer Research MCP Server: Extensible Web Search Capabilities for AI Applications

Overview: What is Developer Research MCP Server?

The Developer Research MCP Server is an API-driven, extensible solution designed to enhance web search functionalities within artificial intelligence (AI) applications and development tools. This server leverages Model Context Protocol (MCP), a standard protocol enabling seamless communication between AI clients and servers offering specialized tools and data services. By integrating the latest research providers like OpenRouter, the Developer Research MPC Server provides precise, technical, and software development-focused search capabilities.

🔧 Core Features & MCP Capabilities

The core features of the Developer Research MCP Server are designed to deliver robust web search functionalities while ensuring extensibility for future integrations with other providers. Key capabilities include:

1. Web Search

• Provider Integration: Initially, the server integrates OpenRouter for its web search functionality.
• Focus Parameters: Allows specifying focus areas such as "technical," "development," or "general" to fine-tune search results.

2. Extensible Architecture

• Modular Design: Each research provider (like OpenRouter) is implemented as a distinct module, adhering to a common interface for ease of integration.
• Dynamic Configurability: Facilitates easy switching between providers based on configuration or request parameters in the future.

3. Error Handling & Retries

• Reliable Mechanisms: Implements error handling and retry mechanisms to ensure consistent service availability even under network disruptions.

4. Consistent Response Format

• Structured Output: Returns results in a well-structured, consistent JSON format suitable for programmatic use by AI applications.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Developer Research MCP Server is built around a modular design that supports seamless integration with different research providers. Each provider is encapsulated within a specific module, ensuring independence and ease of maintenance. The server adheres to Model Context Protocol (MCP) for standardized communication between clients—such as AI applications—and servers.

1. Modular Architecture

• Provider Modules: Each research provider (e.g., OpenRouter) operates independently yet seamlessly integrates with the main server.
• Common Interface: Adherence to a common interface ensures that different providers can be swapped or enhanced without altering the core functionality of the server.

🚀 Getting Started with Installation

To set up the Developer Research MCP Server, follow these steps:

1. Clone the Repository

git clone https://github.com/yourusername/developer-research-server.git # Replace with the actual URL
cd developer-research-server

2. Install Dependencies

Install the necessary dependencies using npm.

npm install

3. Build the Project

Compile the TypeScript code to JavaScript for execution.

npm run build

The compiled output will be in the build/ directory.

💡 Key Use Cases in AI Workflows

This MCP server can significantly enhance the capabilities of various AI applications by providing highly targeted web search functionalities. Here are two real-world use cases:

1. Developer Documentation Lookup

An AI developer’s assistant application could utilize this server to retrieve detailed documentation and examples for complex programming tasks.

Implementation:

const searchResults = await useMcpTool("developer-research", "search_web", {
  query: "React hook useRef",
  num_results: 3,
  focus: "technical",
});

console.log(searchResults);

2. Technical Support Assistance

A customer support chatbot can leverage the server to provide users with relevant technical solutions and guidelines based on their queries.

Implementation:

const searchResults = await useMcpTool("developer-research", "search_web", {
  query: "React component lifecycle methods",
  num_results: 5,
  focus: "development",
});

console.log(searchResults);

🔌 Integration with MCP Clients

To integrate this server into an AI application, you can add the following configuration to your .roo/mcp.json file:

{
  "mcpServers": {
    "[server-name]": {
      "command": "node",
      "args": ["/full/path/to/your/developer-research-server/build/index.js"], // Update this path
      "env": {
        "OPENROUTER_API_KEY": "your-openrouter-api-key", // Load from .env or set explicitly
        "OPENROUTER_API_URL": "https://openrouter.ai/api/v1"
      },
      "alwaysAllow": ["search_web"], // Tools the agent can always use
      "timeout": 60 // Timeout in seconds
    }
  }
}

Replace /full/path/to/your/developer-research-server/build/index.js with the correct absolute path on your system. Ensure OPENROUTER_API_KEY is securely configured via a .env file to avoid hardcoding secrets.

📊 Performance & Compatibility Matrix

The Developer Research MCP Server ensures compatibility and performance across multiple AI clients, as detailed below:

Client	API Key Required	Tools	Prompts
Claude Desktop	Yes	Yes	Yes
Continue	Yes	Yes	Yes
Cursor	No	Yes	No

🛠️ Advanced Configuration & Security

To configure the server with environment variables, follow these steps:

1. Create a .env File

Copy mcp-config-sample.json (or create one manually) to your project root and update it with necessary API credentials.

# Example .env file content:
OPENROUTER_API_KEY=your_openrouter_api_key_here
OPENROUTER_API_URL=https://openrouter.ai/api/v1

Ensure the .env file is added to your .gitignore to avoid committing secrets.

2. Required Environment Variables

• OPENROUTER_API_KEY: Your unique OpenRouter API key.
• OPENROUTER_API_URL (Optional): The base URL for the OpenRouter API. Defaults to https://openrouter.ai/api/v1.
