🔍 Search Providers

Available Providers

| Provider | Best For | Free Tier | API Key Required | |----------|----------|-----------|------------------| | Tavily | AI-optimized research | 1,000/month | Yes - Get Key | | Serper | Google search results | 2,500/month | Yes - Get Key | | Google | Custom search | 100/day | Yes - Setup | | DuckDuckGo | Privacy-focused | Unlimited | No |

Choosing the Right Provider

• Tavily: Best for AI research, academic papers, technical topics
• Serper: Best for current events, general web search, Google quality
• Google Custom Search: Best for specific domains, controlled results
• DuckDuckGo: Best for privacy-sensitive research, no API needed

Using Multiple Providers

// Configure multiple providers for redundancy
const researcher = new GPTResearch({
  query: 'Your research topic',
  retrievers: ['tavily', 'serper'], // Falls back if one fails
  apiKeys: {
    tavily: process.env.TAVILY_API_KEY,
    serper: process.env.SERPER_API_KEY
  }
});

🔌 MCP (Model Context Protocol) Support

GPT Research now supports MCP for connecting to external tools and services!

What is MCP?

MCP (Model Context Protocol) is a standardized protocol for connecting AI systems to external tools and data sources. It enables seamless integration with various services through a unified interface.

MCP Features

• Stdio MCP Servers - Local process spawning for NPX/binary tools (Node.js/Docker/VPS)
• HTTP MCP Servers - RESTful API connections (works everywhere including Vercel)
• WebSocket MCP - Real-time bidirectional communication (works everywhere)
• Tool Discovery - Automatic discovery of available tools from all server types
• Smart Selection - AI-powered tool selection based on research query
• Streaming Updates - Real-time progress tracking via SSE
• Mixed Mode - Combine stdio, HTTP, and WebSocket in the same application

MCP Usage Examples

HTTP/WebSocket MCP (Works everywhere including Vercel)

const researcher = new GPTResearch({
  query: "Latest AI developments",
  mcpConfigs: [
    {
      name: "research-tools",
      connectionType: "http",
      connectionUrl: "https://mcp.example.com",
      connectionToken: process.env.MCP_TOKEN
    }
  ],
  useMCP: true
});

Stdio MCP (Local tools - Node.js environments)

const researcher = new GPTResearch({
  query: "Analyze this codebase",
  mcpConfigs: [
    {
      name: "filesystem",
      connectionType: "stdio",
      command: "npx",
      args: ["@modelcontextprotocol/filesystem-server"],
      env: { READ_ONLY: "false" }
    },
    {
      name: "git",
      connectionType: "stdio",
      command: "git-mcp",
      args: ["--repo", "."]
    }
  ]
});

Mixed Mode (Combine all connection types)

const researcher = new GPTResearch({
  query: "Research topic",
  mcpConfigs: [
    // Local tools via stdio
    { name: "local-fs", connectionType: "stdio", command: "npx", args: ["fs-mcp"] },
    // Remote API via HTTP
    { name: "api", connectionType: "http", connectionUrl: "https://api.example.com/mcp" },
    // Real-time via WebSocket
    { name: "stream", connectionType: "websocket", connectionUrl: "wss://realtime.example.com" }
  ]
});

MCP Deployment Compatibility

| MCP Type | Local/Node.js | Vercel | Docker | VPS/Cloud | |----------|---------------|--------|---------|-----------| | HTTP Servers | ✅ Full | ✅ Full | ✅ Full | ✅ Full | | WebSocket | ✅ Full | ✅ Full | ✅ Full | ✅ Full | | Stdio | ✅ Full | ❌ Not Supported | ✅ Full | ✅ Full |

Stdio MCP Notes:

• Works perfectly in Node.js, Docker, VPS, and self-hosted environments
• Not supported on Vercel, AWS Lambda, or other serverless platforms
• For serverless deployments, use HTTP/WebSocket MCP or deploy a proxy server

Popular Stdio MCP Servers

These MCP servers can be run locally via stdio:

# File System Access
npx @modelcontextprotocol/filesystem-server

# Git Repository Tools  
npx @modelcontextprotocol/git-server

# Database Query Execution
npm install -g mcp-database
mcp-database

# Custom Python MCP Server
python -m mcp.server

# Shell Command Execution
cargo install mcp-shell
mcp-shell

🌐 Vercel Deployment

API Routes

Create API routes in your Next.js/Vercel project:

// api/research/route.js
import { GPTResearch } from 'gpt-research';

export async function POST(request) {
  const { query, reportType } = await request.json();
  
  const researcher = new GPTResearch({
    query,
    reportType,
    apiKeys: {
      openai: process.env.OPENAI_API_KEY,
      tavily: process.env.TAVILY_API_KEY
    }
  });
  
  const result = await researcher.conductResearch();
  
  return Response.json(result);
}

Streaming API

// api/research/stream/route.js
export async function POST(request) {
  const { query } = await request.json();
  
  const stream = new ReadableStream({
    async start(controller) {
      const researcher = new GPTResearch({ query });
      
      for await (const update of researcher.streamResearch()) {
        controller.enqueue(
          `data: ${JSON.stringify(update)}\n\n`
        );
      }
      
      controller.close();
    }
  });
  
  return new Response(stream, {
    headers: {
      'Content-Type': 'text/event-stream',
      'Cache-Control': 'no-cache',
      'Connection': 'keep-alive'
    }
  });
}

📊 Performance Considerations

• Token Limits: Automatically manages context within token limits
• Concurrent Operations: Configurable concurrency for searches and scraping
• Cost Optimization: Uses appropriate models for different tasks
• Caching: Caches scraped content to avoid redundant operations
• Memory Management: Efficient in-memory storage with export/import capabilities

🔐 Security

• API Key Management: Never commit API keys to version control
• Input Validation: All URLs and inputs are validated
• Rate Limiting: Built-in rate limiting for API calls
• Error Handling: Comprehensive error handling and recovery

🎯 Roadmap

• [ ] Add multi-language support
• [ ] Add more LLM providers (Cohere, Together AI)
• [ ] Implement research templates
• [ ] Add PDF and DOCX report export

💡 Tips

1. Use Tavily for best results - It's specifically designed for AI research
2. Configure multiple search providers - Automatic fallback ensures reliability
3. Adjust concurrency based on your limits - Prevent rate limiting
4. Use streaming for long research - Better user experience
5. Monitor costs - Track LLM usage to manage expenses

🆘 Troubleshooting

Common Issues

Build Errors: Make sure you have Node.js 18+ and run npm install

API Key Errors: Verify your API keys are correct in .env

Rate Limiting: Reduce scrapingConcurrency and maxSearchResults

Memory Issues: For large research, increase Node.js memory:

node --max-old-space-size=4096 your-script.js
