The changelog entry for #620 listed add_mcp_server()/remove_mcp_server(), but the commit actually added reconnect_mcp_server()/toggle_mcp_server()/ stop_task() and the McpStatusResponse type. The commit's own CHANGELOG block had the correct names; this was a transcription error.

Adds MCP server control methods and a typed

get_mcp_status()returnChanged return type from
dict[str, Any]→McpStatusResponse(TypedDict). Runtime-safe — it's still a dict — but callers now get typed access tostatus["mcpServers"]withMcpServerStatusentries (name,status,config,scope,tools,serverInfo,error).Status enum:
'connected' | 'failed' | 'needs-auth' | 'pending' | 'disabled'Wire format note: the
