base on Exa MCP for web search and web crawling! # Exa MCP Server 🔍 [](https://cursor.com/en/install-mcp?name=exa&config=eyJuYW1lIjoiZXhhIiwidHlwZSI6Imh0dHAiLCJ1cmwiOiJodHRwczovL21jcC5leGEuYWkvbWNwIn0=) [](https://vscode.dev/redirect/mcp/install?name=exa&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.exa.ai%2Fmcp%22%7D) [](https://www.npmjs.com/package/exa-mcp-server) [](https://smithery.ai/server/exa) ## Exa Code: fast, efficient web context for coding agents Vibe coding should never have a bad vibe. `exa-code` is a huge step towards coding agents that never hallucinate. When your coding agent makes a search query, `exa-code` searches over billions of Github repos, docs pages, Stackoverflow posts, and more, to find the perfect, token-efficient context that the agent needs to code correctly. It's powered by the Exa search engine. Examples of queries you can make with `exa-code`: * use Exa search in python and make sure content is always livecrawled * use correct syntax for vercel ai sdk to call gpt-5 nano asking it how are you * how to set up a reproducible Nix Rust development environment **✨ Works with Cursor and Claude Code!** Use the HTTP-based configuration format: ```json { "mcpServers": { "exa": { "type": "http", "url": "https://mcp.exa.ai/mcp", "headers": {} } } } ``` You can enable specific tool(s) using the `tools` parameter (if multiple, then with a comma-separated list): ``` https://mcp.exa.ai/mcp?tools=web_search_exa,get_code_context_exa ``` Or enable all tools: ``` https://mcp.exa.ai/mcp?tools=web_search_exa,get_code_context_exa,crawling_exa,company_research_exa,linkedin_search_exa,deep_researcher_start,deep_researcher_check ``` You may include your exa api key in the url like this: ``` https://mcp.exa.ai/mcp?exaApiKey=YOUREXAKEY ``` **Note:** By default, only `web_search_exa` and `get_code_context_exa` are enabled. Add other tools as needed using the `tools` parameter. --- A Model Context Protocol (MCP) server that connects AI assistants like Claude to Exa AI's search capabilities, including web search, research tools, and our new code search feature. ## 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 ``` ### 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" ] } } } ``` ### Cursor and Claude Code Configuration for Remote MCP For Cursor and Claude Code, use this HTTP-based configuration format: ```json { "mcpServers": { "exa": { "type": "http", "url": "https://mcp.exa.ai/mcp", "headers": {} } } } ``` ### Codex Configuration for Remote MCP Open your Codex configuration file: ```bash code ~/.codex/config.toml ``` Add this configuration: ```toml [mcp_servers.exa] command = "npx" args = ["-y", "mcp-remote", "https://mcp.exa.ai/mcp"] 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). ### Claude Code Plugin The easiest way to get started with Exa in Claude Code, using plugins: ```bash # Add the Exa marketplace /plugin marketplace add exa-labs/exa-mcp-server # Install the plugin /plugin install exa-mcp-server ``` Then set your API key: ```bash export EXA_API_KEY="your-api-key-here" ``` Get your API key from [dashboard.exa.ai/api-keys](https://dashboard.exa.ai/api-keys). ### NPM Installation ```bash npm install -g exa-mcp-server ``` ### Using Claude Code ```bash claude mcp add exa -e EXA_API_KEY=YOUR_API_KEY -- npx -y exa-mcp-server ``` ### Using Exa MCP through Smithery To install the Exa MCP server via [Smithery](https://smithery.ai/server/exa), head over to: [smithery.ai/server/exa](https://smithery.ai/server/exa) ## 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 powerful tools for developers and researchers: #### 🌐 **Tools** - **get_code_context_exa**: Search and get relevant code snippets, examples, and documentation from open source libraries, GitHub repositories, and programming frameworks. Perfect for finding up-to-date code documentation, implementation examples, API usage patterns, and best practices from real codebases. - **web_search_exa**: Performs real-time web searches with optimized results and content extraction. - **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. - **linkedin_search**: Search LinkedIn for companies and people using Exa AI. Simply include company names, person names, or specific LinkedIn URLs in your query. - **deep_researcher_start**: Start a smart AI researcher for complex questions. The AI will search the web, read many sources, and think deeply about your question to create a detailed research report. - **deep_researcher_check**: Check if your research is ready and get the results. Use this after starting a research task to see if it's done and get your comprehensive report. **Note:** By default, only `web_search_exa` and `get_code_context_exa` are enabled. You can enable additional tools using the `tools=` parameter (see examples below). #### 💻 **Setup for Code Search Only** (Recommended for Developers) ```json { "mcpServers": { "exa": { "command": "npx", "args": [ "-y", "exa-mcp-server", "tools=get_code_context_exa" ], "env": { "EXA_API_KEY": "your-api-key-here" } } } } ``` #### Enable All Tools: You can either enable all tools or any specfic tools. Use a comma-separated list to enable the tools you need: ```json { "mcpServers": { "exa": { "command": "npx", "args": [ "-y", "exa-mcp-server", "tools=get_code_context_exa,web_search_exa,company_research_exa,crawling_exa,linkedin_search_exa,deep_researcher_start,deep_researcher_check" ], "env": { "EXA_API_KEY": "your-api-key-here" } } } } ``` ## Using via NPX If you prefer to run the server directly, you can use npx: ```bash # Run with default tools only (web_search_exa and get_code_context_exa) npx exa-mcp-server # Enable specific tools only npx exa-mcp-server tools=web_search_exa # All tools npx exa-mcp-server tools=web_search_exa,get_code_context_exa,crawling_exa,company_research_exa,linkedin_search_exa,deep_researcher_start,deep_researcher_check ``` --- 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"
