# 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.

## read_call_recordings
Get a short-lived signed URL for a call's recording so it can be listened to or analysed inside the workspace.
Use when a claim about a call needs the audio itself rather than its disposition or transcript summary.
The URL is a real recording of a real customer conversation: do not forward it, do not embed it anywhere durable, and do not treat it as a share — publishing a recording is a separate, confirmed capability. A recording that is still being prepared reports as temporarily unavailable rather than serving the wrong audio.
Scopes: dialer:read
Risk: read; confirmation: none; idempotency: none.
