Connect Gemini Enterprise to the Collibra MCP

October 20, 2026

Gemini Enterprise connects to the Collibra MCP server through a custom MCP server data store configured with OAuth 2.0. Once connected, Gemini can use Collibra's governed metadata tools directly in your conversations, for example to propose a new business term.

Note The Collibra MCP server runs in the Collibra Cloud environment, so this integration is not available for Collibra Platform for Government or Collibra Platform Self-Hosted (CPSH).
