Summary
The Exa MCP Server integrates Exa's search capabilities into AI assistants, providing tools for web search, code search, and company research. It enables LLMs and coding assistants to access real-time web information and specialized search functionality through a standardized protocol. The server solves the problem of giving AI systems current, factual information from the internet and code repositories without requiring separate integrations.

Available Tools
Default Tools
| Tool | Description |
|---|---|
web_search_exa | Search the web for any topic and get clean, ready-to-use content |
web_fetch_exa | Read a webpage's full content as clean markdown from one or more URLs |
Optional Tools (enable via the tools parameter)
| Tool | Description |
|---|---|
agent_run | Run an Exa Agent for multi-step research, list-building, enrichment, and structured output |
web_search_advanced_exa | Advanced search with filters, domains, dates, highlights, summaries, and subpage crawling |
Enable tools by appending them to the MCP URL (this will replace the defaults, so include all you want):
https://mcp.exa.ai/mcp?tools=web_search_advanced_exa
https://mcp.exa.ai/mcp?tools=web_search_exa,web_fetch_exa,agent_run
Exa Agent requires authentication (OAuth or an API key).
Agent Skills
Skills live in skills/ and load with Agent Plugin / Claude plugin installs.
| Skill | Path | Use when |
|---|---|---|
search | skills/search/ | Deep research, lead gen, competitive analysis, multi-step web investigation |
exa-agent | skills/exa-agent/ | Exa Agent runs, enrichment, structured output, Connect providers |
Invoke from your client's skill UI (or /skill-name where supported). MCP-only setups still get the tools; skills add orchestration on top.
Authentication
The hosted MCP server works anonymously with rate limits. For higher limits and access to Exa Agent, use either OAuth or an API key.
OAuth is preferred: most clients prompt you to sign in to Exa. To force the login flow (useful for shared connectors and plugins), use https://mcp.exa.ai/mcp?login or https://mcp.exa.ai/mcp/oauth.
If you prefer, you can get an API key from the dashboard and pass it on the URL as ?exaApiKey=…. You can also send it as a Authorization: Bearer … header or an x-api-key header.
