# 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.

## test_booking_connection

Probe a booking connection by fetching the connected account's profile.

Use to distinguish a revoked grant from a provider outage before telling a human to reconnect.

A `connected: false` result is a normal outcome, not an error to retry.

Scopes: integration:read

Risk: read; confirmation: none; idempotency: none.
