Exa MCP Server 🔍
🆕 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:
{
"mcpServers": {
"exa": {
"type": "http",
"url": "https://mcp.exa.ai/mcp",
"headers": {
"Remove-Me": "Disable web_search_exa tool if you're just coding. To 100% call exa-code, say 'use exa-code'."
}
}
}
}
You may include your exa api key in the url like this:
https://mcp.exa.ai/mcp?exaApiKey=YOUREXAKEY
You may whitelist specific tools in the url with the enabledTools parameter which expects a url encoded array strings like this:
https://mcp.exa.ai/mcp?exaApiKey=YOUREXAKEY&enabledTools=%5B%22crawling_exa%ss%5D
You can also use exa-code through Smithery without an Exa API key.
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).

"type": "http",
"url": "https://mcp.exa.ai/mcp",
"headers": {}
}
}

NPM Installation
npm install -g exa-mcp-server
Using Claude Code
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, head over to:
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:
- Open your Claude Desktop configuration:
code ~/Library/Application\ Support/Claude/claude_desktop_config.json
For Windows:
- Open your Claude Desktop configuration:
code %APPDATA%\Claude\claude_desktop_config.json
2. Add the Exa server configuration:
{
"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.
3. Available Tools & Tool Selection
The Exa MCP server includes powerful tools for developers and researchers:
🔥 Featured: Code Search Tool
- get_code_context_exa: 🆕 NEW! 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.
🌐 Other Available Tools
- 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.
You can choose which tools to enable by adding the --tools parameter to your Claude Desktop configuration:
💻 Setup for Code Search Only (Recommended for Developers)
{
"mcpServers": {
"exa": {
"command": "npx",
"args": [
"-y",
"exa-mcp-server",
"--tools=get_code_context_exa,web_search_exa"
],
"env": {
"EXA_API_KEY": "your-api-key-here"
}
}
}
}
Specify which tools to enable:
{
"mcpServers": {
"exa": {
"command": "npx",
"args": [
"-y",
"exa-mcp-server",
"--tools=get_code_context_exa,web_search_exa,company_research,crawling,linkedin_search,deep_researcher_start,deep_researcher_check"
],
"env": {
"EXA_API_KEY": "your-api-key-here"
}
}
}
}
For enabling multiple tools, use a comma-separated list:
{
"mcpServers": {
"exa": {
"command": "npx",
"args": [
"-y",
"exa-mcp-server",
"--tools=get_code_context_exa,web_search_exa,company_research,crawling,linkedin_search,deep_researcher_start,deep_researcher_check"
],
"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:
- Completely quit Claude Desktop (not just close the window)
- Start Claude Desktop again
- 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:
# 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,get_code_context_exa
# List all available tools
npx exa-mcp-server --list-tools
