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

    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",
    }
  }
}

    Exa MCP works with most other clients, point them at https://mcp.exa.ai/mcp.

    Available Tools

    Default Tools

    ToolDescription
    web_search_exaSearch the web for any topic and get clean, ready-to-use content
    web_fetch_exaRead a webpage's full content as clean markdown from one or more URLs

    Optional Tools (enable via the tools parameter)

    ToolDescription
    agent_runRun an Exa Agent for multi-step research, list-building, enrichment, and structured output
    web_search_advanced_exaAdvanced 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.

    SkillPathUse when
    searchskills/search/Deep research, lead gen, competitive analysis, multi-step web investigation
    exa-agentskills/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.
