Overview
Exa MCP
Exa MCP Server is a hosted MCP connector that gives AI agents web search, page fetching as clean markdown, and multi-step research through Exa's API. Optional tools add filtered advanced search and Exa Agent runs for research, enrichment, and structured output. Use it when an agent needs live web search, clean page content, or a multi-step research task. Anonymous use works with rate limits; OAuth or an API key is only needed for higher limits or Exa Agent access.
What it does
Exa MCP Server connects an AI agent to Exa's web search, page-fetching, and multi-step research API. It's hosted, so there's nothing to run yourself: point a client at https://mcp.exa.ai/mcp and it can search the web, pull a page's full content as clean markdown, or hand off multi-step research to an Exa Agent.
When to use - and when NOT to
Use it when an agent needs to search the live web, fetch a specific page's content without HTML noise, or run a longer research task - list-building, enrichment, structured output - that goes beyond a single search call. Anonymous use works out of the box with rate limits, so it's not necessary to sign up just to try it; sign in with OAuth or an API key only once you need higher limits or access to the Exa Agent tool, which requires authentication.
Capabilities
Two tools are on by default: web_search_exa (search any topic, get clean ready-to-use content) and web_fetch_exa (read one or more URLs' full content as clean markdown). Two more are optional and enabled by adding ?tools=... to the server URL, which replaces the defaults rather than adding to them: web_search_advanced_exa (filters by domain and date, highlights, summaries, and subpage crawling) and agent_run (runs an Exa Agent for multi-step research, list-building, enrichment, or structured output, and requires OAuth or an API key). Two Agent Skills ship alongside the MCP tools for clients that support them - search for deep research and competitive analysis, and exa-agent for orchestrating Exa Agent runs - loaded automatically with an Agent Plugin or Claude plugin install; MCP-only setups still get all the tools, just without that orchestration layer.
How to install
Point any MCP client at the hosted endpoint:
https://mcp.exa.ai/mcp
Claude installs via the Plugin Marketplace or claude plugin install exa@claude-plugins-official; Codex/ChatGPT via codex mcp add exa --url https://mcp.exa.ai/mcp; most other clients, including Cursor, VS Code, Kiro, LM Studio, Replit, Windsurf, Zed, Gemini CLI, and OpenCode, take the same URL in a standard mcpServers block with "type": "streamable-http". Grok Build installs it from its /marketplace, then /mcp to sign in. For higher rate limits, sign in via OAuth (append ?login to force the flow) or pass an API key as ?exaApiKey=..., an Authorization: Bearer header, or an x-api-key header.
Who it's for
Developers adding live web search, page fetching, or multi-step research to an AI agent without standing up their own search infrastructure.

Installation
Connect to Exa's hosted MCP server:
https://mcp.exa.ai/mcp
Or use a plugin when your client supports one.
Agent Plugin
This repository is an Agent Plugin. Install it with any compatible client.
Claude
Install from the Claude Plugin Marketplace, or run:
claude plugin install exa@claude-plugins-official
Codex / ChatGPT
Install via Plugins in ChatGPT, or run:

Other MCP Clients
Most clients can be configured manually with the standard mcpServers shape:
{
"mcpServers": {
"exa": {
"type": "streamable-http",
"url": "https://mcp.exa.ai/mcp",
}
}
}
Client-specific configs
Exa MCP works with most other clients, point them at https://mcp.exa.ai/mcp.

| Replit | Add to Replit |
| Grok Build | /marketplace → install Exa, then /mcp to sign in |
| Gemini CLI | Add manually to ~/.gemini/settings.json |
| OpenCode | Add manually to opencode.json |
| Windsurf | Add manually to ~/.codeium/windsurf/mcp_config.json |

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.
