## October 12, 2026

Announcement OAuth 2.0 clients calling the Google Slides Model Context Protocol (MCP) server
are required to have **Use this client for an AI-powered agent** selected in
**Google Auth Platform** **\>** **Clients**.

Starting November 11, 2026, Google Workspace MCP servers will reject requests
from any app or integration whose OAuth client is not marked as agentic by
selecting **Use this client for an AI-powered agent**. OAuth clients that are
not marked as agentic by November 12, 2026 will remain non-agentic and can't
call Google Workspace MCP servers. To use MCP after this date, you will need to
create a new OAuth client marked as agentic and update your app to use it.

Apps and integrations that are not AI agents, like those that only call Google
Workspace REST APIs, are not affected by this change. If an existing OAuth
client is used for both AI agent and non-agent features, create a separate OAuth
client for the AI agent and mark only that client as agentic. Keep the existing
client for your non-agent features.

The Google Slides MCP server is available as part of the [Developer Preview
Program](https://developers.google.com/workspace/preview). For instructions on
configuring an OAuth 2.0 client for the Google Slides MCP server, see [Set up
the Google Slides MCP
server](https://developers.google.com/workspace/slides/api/guides/configure-mcp-server#configure-mcp-client)
and [Manage OAuth Clients](https://support.google.com/cloud/answer/15549257).
