GAIA natively supports the Model Context Protocol (MCP), an open standard that lets AI assistants talk to external tools. Connect any compatible server and GAIA indexes its tools, then picks the right one automatically when you ask for something. You never have to think about which integration to use.

GAIA probes the server, detects its authentication requirements, and connects automatically.

Authorize (OAuth only)

If the server uses OAuth, you’ll be redirected to the provider’s authorization page. Grant access and you’ll land back in GAIA, connected.
Once connected, GAIA imports every tool the server exposes and confirms the count, for example: “Connected to Notion MCP with 12 tools!” Those tools work in chat immediately.
If a connection fails, the integration is still saved. Retry from the Integrations page at any time.

​
Authentication, handled for you

You don’t need to know which auth type a server uses, provide the URL and GAIA figures it out.

No Auth

The server is publicly accessible. Provide the URL and you’re connected.

Bearer Token

The server requires an API key. Enter it in the API Key field and GAIA sends it with every request.

OAuth 2.1

GAIA handles the full flow, PKCE, token refresh, and dynamic client registration. Just leave the API Key field empty.

Notion

Read and write Notion pages, databases, and blocks directly from chat.

Postman

Run API collections and manage your Postman workspace.

Context7

Pull up-to-date documentation for any library directly into your conversation.

GitHub

Manage repositories, issues, pull requests, and code search.
Any server that implements the MCP specification works with GAIA. Browse the MCP server directory for more.

​
Publishing to the marketplace

You can skip this unless you’ve built or configured a server others would find useful. Publish it to the GAIA community marketplace and any GAIA user can install it with one click.
Test your integration thoroughly before publishing. Make sure all tools work reliably and the server is stable.
