What is the Tavily MCP?

Tavily is a search API purpose-built for AI agents, providing fast, relevant, and factual web search results with clean content extraction. The Tavily MCP brings real-time web search into Claude Code, allowing Claude to retrieve current information, research unfamiliar topics, verify facts, and ground its responses with live data from across the web.

Installation

mcpizy install tavily

Create an account at tavily.com and copy your API key. Free tier provides 1,000 API calls per month. Provide the key during MCPizy setup.

Key Capabilities

Web search — retrieve ranked, relevant search results with extracted content from each page.
News search — filter results to recent news articles for current-events research.
Deep research mode — perform multi-step research that synthesizes information from multiple sources.
Domain filtering — restrict search results to specific domains (e.g., only official documentation sites).
Answer extraction — get a direct answer to a factual question along with supporting sources.

Example Usage

Research recent changes to a cloud provider's pricing before building a cost estimator:

// Claude will:
// 1. Search "AWS Lambda pricing 2026" with Tavily
// 2. Extract relevant pricing information from the top results
// 3. Cross-reference against the official AWS pricing page
// 4. Use the verified, current data in the cost estimator logic

Tips and Best Practices

Use domain filtering (e.g., include_domains=["docs.aws.amazon.com"]) to get authoritative answers rather than blog opinions.
Combine with Context7 MCP for a complete research setup — Context7 for library docs, Tavily for everything else.
Use the answer mode for quick factual lookups (e.g., "what is the current Node.js LTS version?").
Tavily's content extraction is cleaner than raw HTML scraping — it is a good first choice before resorting to Firecrawl for single-page scraping.
