Remote control connections can now reconnect/toggle MCP servers, rename sessions, stop tasks, and set effort/ultracode flags

What

A large set of new remote-control commands lets a connected controller (such as a bridge or host application) manage a running Claude Code session from outside it:

  • mcp_reconnect forces an MCP (Model Context Protocol) server connection to reconnect
  • mcp_toggle enables or disables an MCP server remotely, while still respecting any enterprise-managed policy that blocks it
  • set_mcp_permission_mode_override lets a caller pin an MCP server's permission mode to default or auto, but only in the tightening direction
  • generate_session_title and rename_session let a remote peer generate or set the session's title
  • stop_task and background_tasks let a remote peer stop or background running tasks
  • a new flag-settings handler lets a remote peer set the session's effortLevel (the default effort level used for models without their own saved level) and a new ultracode boolean
Why

These additions give external tools and integrations much finer remote control over a running Claude Code session, letting them manage MCP servers, session naming, running tasks, and effort settings without the user driving the terminal directly.
