# 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.

## reattach_integration_share

Re-attach a shared connection this workspace previously detached.

Use when a detached workspace should use the shared connection again. Paused workflows stay paused until resumed.

Fails when the share was revoked or this workspace now has its own connection of the provider.

Obtain the user's explicit authorization before invoking a write or destructive action. This is a client interaction requirement, not a server-issued approval token.

Scopes: integration:create

Risk: write; confirmation: explicit; idempotency: supported.
