Usage with MCP

Add the Tavily MCP server to your MCP configuration:

{
  "mcpServers": {
    "tavily": {
      "command": "npx",
      "args": ["-y", "@mcptools/mcp-tavily"],
      "env": {
        "TAVILY_API_KEY": "your-api-key"
      }

Search Tools

The server provides three search tools that can be called through MCP:

1. Basic Search

// Tool name: search
{
  query: "artificial intelligence",
  options: {
    searchDepth: "advanced",
    topic: "news",
    maxResults: 10
  }
}

2. Context Search

// Tool name: searchContext
{
  query: "latest developments in AI",
  options: {
    topic: "news",
    timeRange: "week"
  }
}

3. Q&A Search

// Tool name: searchQNA
{
  query: "What is quantum computing?",
  options: {
    includeAnswer: true,
    maxResults: 5
  }
}

Extract Tool

// Tool name: extract
{
  urls: ["https://example.com/article1", "https://example.com/article2"],
  options: {
    extractDepth: "advanced",
    includeImages: true
  }
}

Search Options

All search tools share these options:

interface SearchOptions {
  searchDepth?: "basic" | "advanced";    // Search depth level
  topic?: "general" | "news" | "finance"; // Search topic category
  days?: number;                         // Number of days to search
  maxResults?: number;                   // Maximum number of results
  includeImages?: boolean;               // Include images in results
  includeImageDescriptions?: boolean;    // Include image descriptions
  includeAnswer?: boolean;               // Include answer in results
  includeRawContent?: boolean;           // Include raw content
  includeDomains?: string[];            // List of domains to include
  excludeDomains?: string[];            // List of domains to exclude
  maxTokens?: number;                    // Maximum number of tokens
  timeRange?: "year" | "month" | "week" | "day" | "y" | "m" | "w" | "d"; // Time range for search
}

Extract Options

interface ExtractOptions {
  extractDepth?: "basic" | "advanced";   // Extraction depth level
  includeImages?: boolean;               // Include images in results
}

Response Format

All tools return responses in the following format:
