# 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.

## request_integration

Ask the Scheduler Zero team to support a CRM, email-verification, or phone-verification provider.

Use when the workspace needs a provider the catalog does not offer. `delivered: false` still means the request was recorded.

Never include credentials or customer data in the request; it is forwarded to an issue tracker.
