web_search_exa

Search the web for any topic and get clean, ready-to-use content. Best for: Finding current information, news, facts, people, companies, or answering questions about any topic. Returns: Clean text content from top search results. Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue". Use category:people / category:company to search through Linkedin profiles / companies respectively. If highlights are insufficient, follow up with web_fetch_exa on the best URLs.

Parameters2

query	string	required	Natural language search query. Should be a semantically rich description of the ideal page, not just keywords. Optionally include category:<type> (company, people) to focus results — e.g. 'category:people John Doe software engineer'.
numResults	number	optional	Number of search results to return (default: 10).

Exa MCP Server

Connect AI agents to Exa for web search, content fetching, and multi-step research.

Documentation · NPM Package · Get your API key

Installation

Connect to Exa's hosted MCP server:

code

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:

bash

claude plugin install exa@claude-plugins-official

Codex / ChatGPT

Install via Plugins in ChatGPT, or run:

bash

codex mcp add exa --url https://mcp.exa.ai/mcp

Other MCP Clients

Most clients can be configured manually with the standard mcpServers shape:

json

{
  "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.

Client	Where to add it
Kiro	Use the Kiro power, or add manually to `~/.kiro/settings/mcp.json`
LM Studio	Add to LM Studio, or add manually to `mcp.json`
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`
Google Antigravity	Add manually to `mcp_config.json`
Zed	Add manually to `settings.json` under `context_servers`
Warp	Settings → Agents → MCP servers
v0 by Vercel	Settings → MCP connections

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):

code

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.
