GAIA's integration marketplace is the catalogue of tools GAIA can connect to. It combines native integrations such as Gmail, Slack, Notion, GitHub, and Google Calendar with community-built MCP servers that extend the assistant to other services. Each listing explains what the integration exposes and how to connect it to your account. Use the search field to find a tool by name, filter by category, and sort by popularity, recency, or name. The directory below lists the integrations alphabetically, with further pages linked at the bottom, so you can jump straight to a detail page. If a tool is missing, MCP is the extension path: build the server, publish it, and it can appear here for other users.
