Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| search_messagesA | Search Gmail using Gmail search syntax (e.g. 'from:foo@bar is:unread newer_than:7d'). Returns list of messages with subject/from/date/snippet. |
| get_messageA | Fetch full message by id: headers plus decoded text/plain body. |
| send_messageA | Send an email. Optionally attach local files by absolute path. To reply inside an existing conversation, pass reply_to_message_id (the id of the message you are replying to): the mail is threaded properly (In-Reply-To/References + Gmail threadId), and 'to'/'subject' default to the original sender and 'Re: '. |
| create_draftA | Create a draft (same fields as send_message, including reply_to_message_id). Does not send. |
| list_labelsA | List all Gmail labels with their ids. |
| modify_labelsA | Add and/or remove labels on a message. Use label ids from list_labels. |

Scored across 6 tools
Each tool maps to a distinct Gmail action—labels, search, fetch, send, draft, and label mutation—with no meaningfully overlapping operations. Search/get and send/draft are clearly separated by their stated purpose.
All six tools follow a consistent verb_noun pattern (list_, search_, get_, send_, create_, modify_) with object nouns that make the target clear. There is no mixed naming style or vague verb.
Six tools is well-scoped for a Gmail server; it covers the main read/search/send/organize workflows without sprawl or redundancy. Each tool earns its place in the set.
Core workflows are covered: search messages, fetch detail, send, draft, and modify labels. Minor gaps exist—no draft update/send, label CRUD, or attachment download—but these are acceptable omissions for a focused email tool set.
