base on Exa is Web Search API | This is Exa MCP (Model Context Protocol) # Exa MCP Server 🔍 [](https://www.npmjs.com/package/exa-mcp-server) [](https://smithery.ai/server/exa) A Model Context Protocol (MCP) server lets AI assistants like Claude use the Exa AI Search API for web searches. This setup allows AI models to get real-time web information in a safe and controlled way. ## Remote Exa MCP 🌐 Connect directly to Exa's hosted MCP server (instead of running it locally). ### Remote Exa MCP URL ``` https://mcp.exa.ai/mcp?exaApiKey=your-exa-api-key ``` Replace `your-api-key-here` with your actual Exa API key from [dashboard.exa.ai/api-keys](https://dashboard.exa.ai/api-keys). ### Claude Desktop Configuration for Remote MCP Add this to your Claude Desktop configuration file: ```json { "mcpServers": { "exa": { "command": "npx", "args": [ "-y", "mcp-remote", "https://mcp.exa.ai/mcp?exaApiKey=your-exa-api-key" ] } } } ``` ### NPM Installation ```bash npm install -g exa-mcp-server ``` ### Using Smithery To install the Exa MCP server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/exa): ```bash npx -y @smithery/cli install exa --client claude ``` ## Configuration ⚙️ ### 1. Configure Claude Desktop to recognize the Exa MCP server You can find claude_desktop_config.json inside the settings of Claude Desktop app: Open the Claude Desktop app and enable Developer Mode from the top-left menu bar. Once enabled, open Settings (also from the top-left menu bar) and navigate to the Developer Option, where you'll find the Edit Config button. Clicking it will open the claude_desktop_config.json file, allowing you to make the necessary edits. OR (if you want to open claude_desktop_config.json from terminal) #### For macOS: 1. Open your Claude Desktop configuration: ```bash code ~/Library/Application\ Support/Claude/claude_desktop_config.json ``` #### For Windows: 1. Open your Claude Desktop configuration: ```powershell code %APPDATA%\Claude\claude_desktop_config.json ``` ### 2. Add the Exa server configuration: ```json { "mcpServers": { "exa": { "command": "npx", "args": ["-y", "exa-mcp-server"], "env": { "EXA_API_KEY": "your-api-key-here" } } } } ``` Replace `your-api-key-here` with your actual Exa API key from [dashboard.exa.ai/api-keys](https://dashboard.exa.ai/api-keys). ### 3. Available Tools & Tool Selection The Exa MCP server includes the following tools, which can be enabled by adding the `--tools`: - **web_search_exa**: Performs real-time web searches with optimized results and content extraction. - **research_paper_search**: Specialized search focused on academic papers and research content. - **company_research**: Comprehensive company research tool that crawls company websites to gather detailed information about businesses. - **crawling**: Extracts content from specific URLs, useful for reading articles, PDFs, or any web page when you have the exact URL. - **competitor_finder**: Identifies competitors of a company by searching for businesses offering similar products or services. - **linkedin_search**: Search LinkedIn for companies and people using Exa AI. Simply include company names, person names, or specific LinkedIn URLs in your query. - **wikipedia_search_exa**: Search and retrieve information from Wikipedia articles on specific topics, giving you accurate, structured knowledge from the world's largest encyclopedia. - **github_search**: Search GitHub repositories using Exa AI - performs real-time searches on GitHub.com to find relevant repositories, issues, and GitHub accounts. You can choose which tools to enable by adding the `--tools` parameter to your Claude Desktop configuration: #### Specify which tools to enable: ```json { "mcpServers": { "exa": { "command": "npx", "args": [ "-y", "exa-mcp-server", "--tools=web_search_exa,research_paper_search,company_research,crawling,competitor_finder,linkedin_search,wikipedia_search_exa,github_search" ], "env": { "EXA_API_KEY": "your-api-key-here" } } } } ``` For enabling multiple tools, use a comma-separated list: ```json { "mcpServers": { "exa": { "command": "npx", "args": [ "-y", "exa-mcp-server", "--tools=web_search_exa,research_paper_search,company_research,crawling,competitor_finder,linkedin_search,wikipedia_search_exa,github_search" ], "env": { "EXA_API_KEY": "your-api-key-here" } } } } ``` If you don't specify any tools, all tools enabled by default will be used. ### 4. Restart Claude Desktop For the changes to take effect: 1. Completely quit Claude Desktop (not just close the window) 2. Start Claude Desktop again 3. Look for the icon to verify the Exa server is connected ## Using via NPX If you prefer to run the server directly, you can use npx: ```bash # Run with all tools enabled by default npx exa-mcp-server # Enable specific tools only npx exa-mcp-server --tools=web_search_exa # Enable multiple tools npx exa-mcp-server --tools=web_search_exa,research_paper_search # List all available tools npx exa-mcp-server --list-tools ``` ## Troubleshooting 🔧 ### Common Issues 1. **Server Not Found** * Verify the npm link is correctly set up * Check Claude Desktop configuration syntax (json file) 2. **API Key Issues** * Confirm your EXA_API_KEY is valid * Check the EXA_API_KEY is correctly set in the Claude Desktop config * Verify no spaces or quotes around the API key 3. **Connection Issues** * Restart Claude Desktop completely * Check Claude Desktop logs: <br> --- Built with ❤️ by team Exa", Assign "at most 3 tags" to the expected json: {"id":"13179","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
