PedroDnT mcp DEEPwebresearch

A Model Context Protocol (MCP) server for advanced web research.

• Added visit_page tool for direct webpage content extraction
• Optimized performance to work within MCP timeout limits
  • Reduced default maxDepth and maxBranching parameters
  • Improved page loading efficiency
  • Added timeout checks throughout the process
  • Enhanced error handling for timeouts

This project is a fork of mcp-webresearch by mzxrai, enhanced with additional features for deep web research capabilities. We're grateful to the original creators for their foundational work.

To install Deep Web Research Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @PedroDnT/mcp-deepwebresearch --client claude

# Install globally using npm
npm install -g mcp-deepwebresearch

# Or using yarn
yarn global add mcp-deepwebresearch

# Or using pnpm
pnpm add -g mcp-deepwebresearch

# Using npm
npm install mcp-deepwebresearch

# Using yarn
yarn add mcp-deepwebresearch

# Using pnpm
pnpm add mcp-deepwebresearch

After installing the package, add this entry to your claude_desktop_config.json:

{
  "mcpServers": {
    "deepwebresearch": {
      "command": "mcp-deepwebresearch",
      "args": []
    }
  }
}

Location: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "deepwebresearch": {
      "command": "mcp-deepwebresearch",
      "args": []
    }
  }
}

Location: ~/Library/Application Support/Claude/claude_desktop_config.json

This config allows Claude Desktop to automatically start the web research MCP server when needed.

After installation, run this command to install required browser dependencies:

npx playwright install chromium

Simply start a chat with Claude and send a prompt that would benefit from web research. If you'd like a prebuilt prompt customized for deeper web research, you can use the agentic-research prompt that we provide through this package. Access that prompt in Claude Desktop by clicking the Paperclip icon in the chat input and then selecting Choose an integration → deepwebresearch → agentic-research.

1. deep_research

   • Performs comprehensive research with content analysis
   • Arguments:

     {
       topic: string;
       maxDepth?: number;      // default: 2
       maxBranching?: number;  // default: 3
       timeout?: number;       // default: 55000 (55 seconds)
       minRelevanceScore?: number;  // default: 0.7
     }

   • Returns:

     {
       findings: {
         mainTopics: Array<{name: string, importance: number}>;
         keyInsights: Array<{text: string, confidence: number}>;
         sources: Array<{url: string, credibilityScore: number}>;
       };
       progress: {
         completedSteps: number;
         totalSteps: number;
         processedUrls: number;
       };
       timing: {
         started: string;
         completed?: string;
         duration?: number;
         operations?: {
           parallelSearch?: number;
           deduplication?: number;
           topResultsProcessing?: number;
           remainingResultsProcessing?: number;
           total?: number;
         };
       };
     }

2. parallel_search

   • Performs multiple Google searches in parallel with intelligent queuing
   • Arguments: { queries: string[], maxParallel?: number }
   • Note: maxParallel is limited to 5 to ensure reliable performance

3. visit_page

   • Visit a webpage and extract its content
   • Arguments: { url: string }
   • Returns:

     {
       url: string;
       title: string;
       content: string;  // Markdown formatted content
     }

A guided research prompt that helps Claude conduct thorough web research. The prompt instructs Claude to:

• Start with broad searches to understand the topic landscape
• Prioritize high-quality, authoritative sources
• Iteratively refine the research direction based on findings
• Keep you informed and let you guide the research interactively
• Always cite sources with URLs

The server can be configured through environment variables:

• MAX_PARALLEL_SEARCHES: Maximum number of concurrent searches (default: 5)
• SEARCH_DELAY_MS: Delay between searches in milliseconds (default: 200)
• MAX_RETRIES: Number of retry attempts for failed requests (default: 3)
• TIMEOUT_MS: Request timeout in milliseconds (default: 55000)
• LOG_LEVEL: Logging level (default: 'info')

1. Rate Limiting

   • Symptom: "Too many requests" error
   • Solution: Increase SEARCH_DELAY_MS or decrease MAX_PARALLEL_SEARCHES

2. Network Timeouts

   • Symptom: "Request timed out" error
   • Solution: Ensure requests complete within the 60-second MCP timeout

3. Browser Issues

   • Symptom: "Browser failed to launch" error
   • Solution: Ensure Playwright is properly installed (npx playwright install)

This is beta software. If you run into issues:

1. Check Claude Desktop's MCP logs:

   # On macOS
   tail -n 20 -f ~/Library/Logs/Claude/mcp*.log
   
   # On Windows
   Get-Content -Path "$env:APPDATA\Claude\logs\mcp*.log" -Tail 20 -Wait

2. Enable debug logging:

   export LOG_LEVEL=debug
