mcp-researcher

MCP server that gives Claude web research capabilities. Install it and your AI can search, scrape, and synthesize the web in real time.

Install

npm install -g mcp-researcher

Setup

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "researcher": {
      "command": "npx",
      "args": ["mcp-researcher"],
      "env": {
        "TAVILY_API_KEY": "your-tavily-api-key",
        "ANTHROPIC_API_KEY": "your-anthropic-api-key"
      }
    }
  }
}

Restart Claude Desktop. Claude can now search and read the web.

Tools

| Tool | Description | Parameters | |------|-------------|------------| | search_web | Search the web via Tavily | query: string, num_results?: number | | fetch_page | Fetch and read a URL | url: string | | summarize_sources | Fetch multiple URLs and synthesize an answer | urls: string[], question: string |

Example

After installing, ask Claude:

"What are the latest developments in AI agents? Search the web and summarize."

Claude will call search_web, select the best results, fetch_page each one, and synthesize a cited answer.

Known Limitations

• JavaScript-heavy pages (SPAs) may not render correctly — static pages work best.
