Enabled by Default:

Off by Default:

Exa Agent Tools (optional, OAuth or API key required):

Enable additional tools with the tools parameter:

https://mcp.exa.ai/mcp?exaApiKey=YOUR_KEY&tools=web_search_exa,web_search_advanced_exa,web_fetch_exa

If you want to use Exa Agent, enable the optional toolset like so:

https://mcp.exa.ai/mcp?tools=agent_tools

If you want both search and Exa Agent tools enabled:

https://mcp.exa.ai/mcp?tools=web_search_exa,web_fetch_exa,agent_tools

Force OAuth login

To force the OAuth handshake so users sign in with their own Exa account (useful for shared Connectors, Skills, and Plugins), add the login parameter:

https://mcp.exa.ai/mcp?login

Or use the /mcp/oauth endpoint:

https://mcp.exa.ai/mcp/oauth

Both can be combined with the tools parameter:

https://mcp.exa.ai/mcp?tools=web_search_exa,web_fetch_exa,agent_tools&login
https://mcp.exa.ai/mcp/oauth?tools=web_search_exa,web_fetch_exa,agent_tools
