Google Chat: Get a message — MCP tool

Google Chat MCP tool: Fetches one message by its resource name — text, sender, thread, attachments and reaction summaries.

Technical name: get_message

What task it solves

I want to read one specific Google Chat message in full.

Returns the message: text, formattedText, sender, createTime/lastUpdateTime, thread.name, attachment[] metadata and emojiReactionSummaries.

When to use it

Use it to re-read a message before editing or deleting it, to get its thread.name for a threaded reply, or to read attachment metadata with user credentials.

What to provide

  • message — required. The full name spaces/<space>/messages/<message> from list_messages/send_message, or the custom-id form spaces/<space>/messages/client-<id>.

What it returns

One message object; deleted messages return deletionMetadata instead of content.

What changes in Google Chat

The tool reads Google Chat data and does not change it.

Example request

Fetch the message spaces/AAAAAAAAAAA/messages/BBBBBBBBBBB.BBBBBBBBBBB and show its thread name.

Errors and limitations

Requires the chat.messages.readonly (or chat.messages) scope and membership in the space. Access also depends on quotas and upstream API limits.
