# Tavily Cursor MCP Server A custom Tavily MCP server with **underscore-named tools** for Cursor compatibility. ## Why This Exists The official Tavily MCP server uses hyphenated tool names (`tavily-search`, `tavily-extract`) which Cursor's CallMcpTool interface doesn't properly recognize. This custom server uses underscore naming (`tavily_search`, `tavily_extract`) to work seamlessly with Cursor. ## Features - ✅ **tavily_search** - Web search with Tavily API - ✅ **tavily_extract** - Extract clean content from URLs - ✅ **tavily_search_qna** - Direct question answering - ✅ **tavily_search_context** - Generate context for RAG applications ## Installation ### Option 1: Local Installation (Recommended) 1. **Clone or download this directory to your local machine** 2. **Install dependencies:** ```bash cd tavily-cursor-mcp npm install ``` 3. **Make the script executable (Mac/Linux):** ```bash chmod +x index.js ``` 4. **Add to your Cursor `mcp.json`:** ```json { "mcpServers": { "tavily_cursor": { "command": "node", "args": ["/absolute/path/to/tavily-cursor-mcp/index.js"], "env": { "TAVILY_API_KEY": "your-tavily-api-key-here" } } } } ``` **Important:** Replace `/absolute/path/to/tavily-cursor-mcp/` with the actual full path to this directory. ### Option 2: NPM Global Installation 1. **Install globally:** ```bash cd tavily-cursor-mcp npm install -g . ``` 2. **Add to your Cursor `mcp.json`:** ```json { "mcpServers": { "tavily_cursor": { "command": "tavily-cursor-mcp", "env": { "TAVILY_API_KEY": "your-tavily-api-key-here" } } } } ``` ## Configuration ### Cursor MCP Configuration Location - **Windows:** `%APPDATA%\Cursor\User\globalStorage\mcp.json` - **Mac:** `~/.cursor/mcp.json` or workspace `.cursor/mcp.json` - **Linux:** `~/.cursor/mcp.json` or workspace `.cursor/mcp.json` ### Get Your Tavily API Key 1. Go to https://tavily.com 2. Sign up or log in 3. Get your API key from the dashboard 4. Replace `your-tavily-api-key-here` in the config with your actual key ## Usage in Cursor After installation and configuration, restart Cursor completely. Then use in Agent mode: ``` Use tavily_search to find the latest AI developments ``` ``` Use tavily_extract to get the content from https://example.com ``` ``` Use tavily_search_qna to answer: What is the capital of France? ``` ## Available Tools ### tavily_search Search the web using Tavily API. **Parameters:** - `query` (required): Search query - `search_depth`: "basic" or "advanced" (default: "basic") - `topic`: "general" or "news" (default: "general") - `days`: Number of days back for news search (default: 3) - `max_results`: Max results to return (default: 5, max: 20) - `include_images`: Include images (default: false) - `include_answer`: Include AI-generated answer (default: false) - `include_raw_content`: Include raw HTML (default: false) ### tavily_extract Extract clean content from URLs. **Parameters:** - `urls` (required): Array of URLs to extract from ### tavily_search_qna Get direct answers to questions. **Parameters:** - `query` (required): The question to answer - `search_depth`: "basic" or "advanced" (default: "basic") ### tavily_search_context Generate context for RAG applications. **Parameters:** - `query` (required): Search query - `search_depth`: "basic" or "advanced" (default: "basic") - `max_results`: Max results (default: 5) ## Troubleshooting ### Tools not showing up in Cursor 1. Make sure you've **completely quit and restarted Cursor** (not just closed the window) 2. Verify the path in `mcp.json` is correct and absolute 3. Check that Node.js is installed: `node --version` (should be >= 18.0.0) 4. Verify your Tavily API key is correct ### "TAVILY_API_KEY environment variable is required" error Make sure your API key is set in the `env` section of your `mcp.json` configuration. ### Tools discovered but not usable This was the original problem! This server fixes it by using underscores instead of hyphens in tool names. ## Testing You can test the server directly: ```bash TAVILY_API_KEY=your-key-here node index.js ``` Then use the MCP Inspector or send MCP protocol messages via stdin. ## License MIT
