TDQS

A4/5.0

Scored across 4 tools

Disambiguation4/5

send_message, list_spaces, and search_messages are clearly distinct. list_messages and search_messages overlap somewhat in retrieving messages from a space, but their parameters and stated purposes make the intended difference reasonably clear.

Naming Consistency5/5

All tool names follow a consistent verb_noun snake_case pattern: send_message, list_spaces, list_messages, and search_messages. The naming is predictable and makes the action and target resource immediately obvious.

Tool Count5/5

Four tools is a well-scoped size for a focused Google Chat MCP server. Each tool covers a clear use case without unnecessary redundancy or overwhelming surface area.

Completeness3/5

The server covers sending and reading messages plus listing spaces, but it lacks message update/delete operations and has no way to create or retrieve a single space. This leaves notable lifecycle gaps for message management, though basic chat workflows are usable.
