### ⚠️ Changes to be aware of

#### MCP clients no longer drop advertised tools

The built-in MCP server now advertises tools as JSON Schema 2020-12, so strict clients that previously dropped every tool keep the full list. If you register custom MCP tools or prompts: unknown or unauthorized tool calls now return JSON-RPC error `-32602` instead of `isError: true`; `extra.sendNotification` and `extra.sendRequest` are gone; and one prompt `argsSchema` that cannot become JSON Schema (for example `z.date()`) hides every prompt from `prompts/list`.
