# MCP tool reference

1 callable tools.

Use tools/call at https://mcp.schedulerzero.com/mcp with the exact tool name and arguments below. The /tools/ paths in this view are documentation identifiers, not HTTP endpoints. Request execution is disabled for this reference.

Inputs are shown for personal API keys (bound) and for OAuth/delegated agents. Output schemas describe MCP structuredContent: native objects pass through; arrays, scalars and null use a data wrapper. Text content retains the native JSON result.

## set_domain_auto_renew

Turn Scheduler Zero's yearly renewal of a domain on or off.

Use when a person asks to keep or let go of a domain at its next expiry; confirm first, because turning renewal on commits a future charge.

Turning renewal off lets the domain lapse at expiry; it does not transfer or cancel anything now.

Obtain the user's explicit authorization before invoking a write or destructive action. This is a client interaction requirement, not a server-issued approval token.

Scopes: domain:purchase

Risk: costly; confirmation: explicit; idempotency: supported.
