7Permission policies control whether server-executed tools (the pre-built agent toolset and MCP toolset) run automatically, wait for your approval, or have each call evaluated by the server. Custom tools are executed by your application and controlled by you, so they are not governed by permission policies.

10 Managed Agents API requests require the `managed-agents-2026-04-01` beta header, except memory store endpoints, which use `agent-memory-2026-07-22` instead. The SDK sets the correct beta header automatically. See [Beta headers](https://platform.claude.com/docs/en/api/beta-headers#endpoint-specific-headers).
