# 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.

## list_integration_shares

List connections this workspace shares with sibling workspaces and connections shared into it.

Use before sharing, detaching, or troubleshooting a connection that came from another workspace.

Use list_integration_connections for connection health; this lists sharing relationships only.

Scopes: integration:read

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