# 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.

## get_attio_status

Report the workspace's Attio connection status and granted scopes.

Use to poll after connect_attio or to check whether outbound sync scopes are granted.

The result carries no token material; do not look for credentials here.

Scopes: integration:read

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