# 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_capability_bundles

List curated capability bundles so an agent can adopt a focused tool set instead of the whole catalog.

Use at session start to choose the smallest bundle set covering the task at hand.

Bundles are discovery metadata; they never grant authority the credential's scopes do not.

Scopes: agent:capabilities

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