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,deep_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 ~/L
