For example, you can ask your AI agent: *"What's the latest update in the 'Project X' space?"*

To get started with the Chat MCP server, see the following documentation:

- [Set up the Chat MCP server](https://developers.google.com/workspace/chat/api/guides/configure-mcp-server)

- [Chat MCP tool reference](https://developers.google.com/workspace/chat/api/reference/mcp)

To find more available MCP servers, see [Model Context Protocol (MCP) servers in Google Workspace](https://developers.google.com/workspace/guides/configure-mcp-servers).

### Deprecated

**Deprecated:** The method [`setAuthentication(clientId, signingKey)`](https://developers.google.com/apps-script/reference/maps/maps#setAuthentication(String,String)) has been deprecated and is scheduled for sunset in June 2026. This change is because Maps platform [client IDs were deprecated](https://developers.google.com/maps/premium/migrate-client-id#overview) on May 26, 2025, and can't be used after May 31, 2026. Instead, use [`setAuthenticationByKey(apiKey)`](https://developers.google.com/apps-script/reference/maps/maps#setauthenticationbyapikeyapikey) or [`setAuthenticationByKey(apiKey, signingKey)`](https://developers.google.com/apps-script/reference/maps/maps#setauthenticationbyapikeyapikey,-signingkey). To get an API key, refer to the [Client ID Migration Guide](https://developers.google.com/maps/premium/migrate-client-id).

### Feature

**Generally Available:** To authenticate to the Maps service, you can now use an API key with the new methods [`setAuthenticationByKey(apiKey)`](https://developers.google.com/apps-script/reference/maps/maps#setauthenticationbyapikeyapikey) and [`setAuthenticationByKey(apiKey, signingKey)`](https://developers.google.com/apps-script/reference/maps/maps#setauthenticationbyapikeyapikey,-signingkey). To reset authentication to the default mode, use [`resetAuthenticationApiKey()`](https://developers.google.com/apps-script/reference/maps/maps#resetauthenticationapikey).

## Google Calendar API

### Announcement

We have updated the guidance for using Google Meet conferences on Google

By converting, your Google Chat app can use the Google Workspace Add-ons framework, opening up new possibilities for integration and features within Google Chat and across Google Workspace. For example, instead of two distributions — one Google Chat app and one Google Workspace add-on — you can distribute a single Google Workspace add-on through Google Workspace Marketplace that extends Chat apps alongside other Google Workspace host applications, like Gmail, Calendar, and Docs.

To learn more, see [Convert an interactive Google Chat app to a Google Workspace add-on](https://developers.google.com/workspace/add-ons/chat/convert).
