Tavily MCP Server for Claude

Content

Tavily gives Claude real-time access to the web through a search API built for AI agents. Rather than returning a raw page of links, Tavily returns concise, source-cited results and clean extracted content that a model can reason over directly. That makes it a good fit for research tasks, fact-checking, and any workflow where the answer depends on current information beyond the model's training cutoff. The server exposes search and extraction as MCP tools, so Claude can decide when to look something up and ground its response in the results.

Features

• Real-time web search optimized for LLM and agent consumption.
• Concise, source-cited results instead of raw search engine result pages.
• Page extraction that returns clean, readable content from target URLs.
• Tunable search depth so you can trade speed for thoroughness.
• Runs as a standard stdio MCP server that installs into Claude Code and Claude Desktop with one command.
• Maintained by Tavily as the official MCP integration for its search API.

Use Cases

• Answer questions that depend on current information past the model's training cutoff.
• Research a topic and gather source-cited findings in one step.
• Fact-check a claim against live web sources.
• Extract the readable content of a specific page for summarization.
• Power agent workflows that need a reliable, structured search step.

Installation

Claude Code

1. Make sure Node.js 18+ is installed (verify with npx --version).
2. Create a Tavily API key at https://tavily.com.
3. Run: claude mcp add tavily --env TAVILY_API_KEY=YOUR_KEY -- npx -y tavily-mcp@latest
4. Verify the server is registered: claude mcp list

Claude Desktop

1. Create a Tavily API key at https://tavily.com.
2. Open your Claude Desktop configuration file.
3. Add the Tavily server to the mcpServers section using the configuration below, with your key in the env section.
4. Restart Claude Desktop and confirm the server appears.

Configuration

{
  "tavily": {
    "command": "npx",
    "args": ["-y", "tavily-mcp@latest"],
    "env": {
      "TAVILY_API_KEY": "${TAVILY_API_KEY}"
    }
  }
}

Examples

Research a current topic

Ask Claude to search and summarize with sources.

"Search the web for recent developments on this topic and summarize the key points with sources."

Fact-check a claim

Have Claude verify a statement against live sources.

"Check whether this claim is accurate using current web sources, and cite what you find."

Extract a page

Pull clean content from a specific URL for summarization.

"Extract the main content of this article URL and give me a concise summary."

Security

• The server reaches the Tavily API over the network; the queries and URLs you provide are sent to that service to return results.
• Treat search results and extracted page content as untrusted input. A malicious page could include instructions or links, so review before acting on them.
• The Tavily API key is a credential. Store it in an environment variable and keep it out of source control and shared configs.
• Avoid putting secrets or private identifiers into search queries, since they are transmitted to the service.

Troubleshooting

Authentication or 401 errors

Confirm TAVILY_API_KEY is set correctly and the key is active in your Tavily account. Regenerate the key if it may have been revoked, and update the environment variable.

npx cannot resolve the package

Verify Node.js 18+ and npx are installed (npx --version). Networks that block the npm registry will prevent npx -y tavily-mcp@latest from resolving.

Empty results or rate limiting

Free tiers and high request volume can trigger rate limits. Retry after a short wait, reduce request frequency, or review your plan limits in the Tavily dashboard.

Server not listed in Claude Code

Re-run the claude mcp add tavily ... command, then claude mcp list. Confirm the key was passed via --env and that the server was added to the scope (project versus user) you are running in.
