capabilities()

Public

Every analytical method, marked implemented, partial, interface_only, or planned. Interface-only methods return their contract and nothing else — the system never fakes a number it cannot compute.

Callable over MCP as capabilities(). REST mirror GET /v1/capabilities Planned — alpha is MCP-only

Why your agent calls it

Call it before you trust anything else. Every analytical method, marked implemented, partial, interface_only, or planned — so an agent (or a buyer) knows exactly which numbers are real. Interface-only methods return their contract, never a faked result.

Call it from an agent

Over MCP, your agent invokes it on its own when the moment calls for it — just describe the situation. A Python SDK for headless runtimes is planned; this is what the call will look like.

from cascadian import Cascadian

cx = Cascadian(api_key=os.environ["CASCADIAN_API_KEY"])

result = cx.capabilities()

Parameters

None. The call is workspace-scoped by the key that makes it.
