Note

Low Risk
Documentation-only changes that clarify existing MCP/auth behavior without affecting runtime logic.

Overview
Documents MCP support for authenticated users with user groups by adding a new section to ai/model-context-protocol.mdx describing group-based filtering, visibility rules, and the need to pass a bearer token in MCP client config.

Updates authentication docs to reflect this behavior by clarifying the MCP availability note and revising the Feature availability table in deploy/authentication-setup.mdx to state that MCP searches public pages for unauthenticated users and respects user groups for authenticated users.
