# 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_integration_share_options

Show whether a connection can be shared and which sibling workspaces can receive it.

Call before share_integration_connection to pick eligible workspaceIds and see existing targets.

Ineligible workspaces (no permission, or already their own connection) are listed with a reason; do not retry them.

Scopes: integration:read

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