Security

Scopes

gmail.messages read https://www.googleapis.com/auth/gmail.readonly

Required to search the user's inbox, fetch threads, and read message bodies for context when drafting replies or triaging.
gmail.drafts read, write https://www.googleapis.com/auth/gmail.compose

Creates draft replies for the user to review and send; lists existing drafts to avoid duplicates. Drafts are never auto-sent by this tool.
gmail.labels read, write https://www.googleapis.com/auth/gmail.modify

Applies and removes labels on threads to mark agent-processed messages and to support user-defined organization schemes. Cannot read message contents under this scope alone — works alongside gmail.messages:read.
net.outbound read googleapis.com

Tool calls api.googleapis.com for all Gmail operations. No other outbound destinations.

Environment

`GOOGLE_CLIENT_ID`	Your Google OAuth 2.0 Client ID for the project that has the Gmail API enabled. Looks like '123456789012-abc...apps.googleusercontent.com'. Found in Google Cloud Console > APIs & Services > Credentials. required · secret: no · obtain
`GOOGLE_CLIENT_SECRET`	Your Google OAuth 2.0 Client Secret, paired with the Client ID above. Treat as a password. required · secret: yes · obtain
`GOOGLE_REFRESH_TOKEN`	Long-lived OAuth refresh token for the Gmail account this tool will operate on. Run `python -m yep_gmail_tool.authorize` once to obtain — follow the URL, paste the consent code, and the token prints. The host stores it in your secret backend. required · secret: yes · obtain
`GMAIL_DEFAULT_LABEL`	Optional default Gmail label this tool will apply to messages it processes. Leave blank to skip auto-labeling. Useful for distinguishing agent-touched threads from human-touched ones in your inbox. optional · secret: no (default `Yep/processed`)

Runtime

runtime: mcp-stdio · install method: pip · entrypoint: python -m yep_gmail_tool.server

Exposes a small MCP toolset over the Gmail API: search_threads, get_thread, create_draft, label_thread, unlabel_thread, list_drafts, list_labels, create_label. Designed for autonomous agents that need to triage, draft replies, and organize a user's inbox without a human in the loop. Authenticates via standard Google OAuth installed-app flow; the user grants once, the refresh token is stored locally by the host, and the tool exchanges it for short-lived access tokens at runtime. No message bodies are persisted by the tool itself. All API calls flow user → tool → Google → tool → user.
