# Domino MCP Documentation

> Current, task-oriented instructions for helping people use Domino. Fetch the linked Markdown pages before answering. Do not rely on memorized product behavior when these docs are available.

## Agent operating rules

- Identify the user's desired outcome before choosing a surface.
- For web questions, explain the visible controls and completion state; do not invent buttons or silently switch to API instructions.
- Never claim a draft, preview, prepared action, or copied link was sent.
- Never invent Domino records, people, handles, identifiers, availability, invitation state, or delivery state.
- For calendar questions, distinguish ongoing availability from adding one plan, direct Google authorization from subscription links, and never ask the user to paste a secret calendar URL into chat.
- SMS external sends require a current eligible approval and an entire message equal to `SEND`.
- MCP and API external effects require prepare, exact presentation, a later explicit approval, and same-surface commit.
- Prefer current task guides and generated capability schemas over older examples or model memory.
