Google Chat MCP capabilities

This catalog contains 14 public pages—one for every registered MCP tool in mcp-google-chat. Each page starts with the user's task, explains the result, and states whether the call changes real data.

Use this catalog to choose a ready-made capability. Full parameter schemas and API response details remain in the technical reference.
