Claude Desktop Integration

Add the following configuration to your Claude Desktop config file:

Config File Locations:

• Windows: %APPDATA%\Claude\claude_desktop_config.json

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Linux: ~/.config/Claude/claude_desktop_config.json

Basic Configuration

{
  "mcpServers": {
    "web-tools": {
      "command": "web-tools-mcp"
    }
  }
}

Custom Claude CLI Path

If you need to specify a custom Claude CLI path:

{
  "mcpServers": {
    "web-tools": {
      "command": "web-tools-mcp",
      "args": ["--claude-cli-path", "C:\\Users\\PRESTO~1\\AppData\\Roaming\\npm\\claude.cmd"]
    }
  }
}

Tool Usage

research_agent

Intelligent research agent that automatically searches, fetches, and analyzes web sources to answer research questions.

Parameters:

• objectives (required): Array of research questions to answer

• starting_query (required): Initial search query to begin research

• max_calls (optional): Maximum research iterations (default: 5)

• allowed_domains (optional): Array of domains to include in results

• blocked_domains (optional): Array of domains to exclude from results

Features:

• Automatically searches the web and fetches top 3 most relevant sources

• Extracts comprehensive quotes from web content

• Continues research until objectives are met or max iterations reached

• Provides organized results with source citations

web_search

Search the web for information with optional domain filtering.

Parameters:

• query (required): The search query string

• allowed_domains (optional): Array of domains to include in results

• blocked_domains (optional): Array of domains to exclude from results

web_fetch

Fetch and extract content from a specific URL.

Parameters:

• url (required): The URL to fetch content from

Usage Examples

Basic Research

{
  "tool": "research_agent",
  "arguments": {
    "objectives": ["What is Claude AI and what are its main capabilities?"],
    "starting_query": "Claude AI capabilities features"
  }
}

Research with Domain Filtering

{
  "tool": "research_agent", 
  "arguments": {
    "objectives": ["Latest quantum computing breakthroughs in 2024"],
    "starting_query": "quantum computing 2024 breakthroughs",
    "allowed_domains": ["arxiv.org", "nature.com", "science.org"],
    "max_calls": 3
  }
}

Basic Web Search

{
  "tool": "web_search",
  "arguments": {
    "query": "latest developments in quantum computing 2024"
  }
}

How Research Agent Works

1. Search: Performs web searches for the research objectives

2. Fetch: Automatically retrieves content from the top 3 most relevant sources

3. Analyze: Extracts comprehensive quotes that answer research questions

4. Continue: Iterates until objectives are met or max iterations reached

Requirements

• Node.js >= 18.0.0
