Confirm the configured AGENTDRAFT_API_KEY is valid and return the calling agent's identity, priority, scopes, and the owner's timezone (so a client can render slots in the owner's zone).

List slots open to the calling agent within [start, end).

Times are ISO 8601 strings (2026-06-01T14:00:00Z). The result is filtered through the user's focus blocks, buffer rules, and any currently-active holds across sibling agents.

Reserve a slot tentatively. Holds expire automatically (30s TTL by default). A subsequent commit_booking on the same slot promotes the hold to a final booking.

Optional title and invitee ({name, email, notes}) record who the slot is for; both carry through to the eventual commit.

Returns an outranked payload if a higher-priority agent already holds or has committed the slot inside the bump window.

Release a previously-created hold so other agents can claim the slot before the TTL expires.

Finalize a booking. This is the atomic compare-and-swap at the slot level — exactly one agent succeeds per slot in any race window. Returns an outranked payload on 409.

Optional title and invitee ({name, email, notes}) record who the slot is for; both are echoed back and shown to the owner in the dashboard.

Set with_conferencing=True to attach a video meeting link to the committed booking; the link is returned under conferencing.

Cancel a previously-committed booking owned by the calling agent. The slot becomes available to other agents immediately.

Open a human sign-off request and return immediately.

action_type is a namespaced lowercase string such as deploy.production, mailbox.send_external, or billing.refund. summary is the one line a reviewer reads first; evidence is the structured context they need to decide (target, amount, exact draft). Returns {approval_id, status, expires_at}. Requires the approvals:request scope.

Read the current state of one approval request: pending, approved, denied, or expired, plus the reviewer's note once resolved. Safe to poll; it never blocks.

Wait for a human decision, bounded to 120 seconds.

The timeout is clamped to [1, 120] and the poll interval to [1, 30] so no MCP host is left hanging. If the request is still pending when the timeout lapses, the result carries status: "pending" and timed_out: true; call get_approval or wait_for_approval again to keep waiting. Proceed only when the status is approved — denied, expired, and pending all mean stop.
