Google Chat MCP Overview

Google Chat MCP connects AI applications to the Google Chat API through an authenticated MCP interface. It can discover spaces and direct messages, read conversations, send or update messages, manage reactions and memberships, and inspect attachment metadata. OAuth setup starts from the conversation and uses a local PKCE redirect, making it suitable for agents that need to review or act on Google Chat as the signed-in user.

Primary Use Cases for Google Chat MCP:
  • Summarize decisions from a Google Chat space
  • Reply to a deployment thread
  • Find an existing direct message
  • Review reactions and attachment metadata
