Anything anchored to your local machine is rejected rather than silently failing.\n\n**Details**\n\n- Handled locally: initialize, interrupt, end_session, cancel_async_message. Forwarded with sends held: set_model, mcp_toggle, rewind_conversation, set_permission_mode and others.\n- Rejected because they name a path on this machine: set_cwd, add_directory, register_repo_root, rewind_files.\n- Also rejected: mcp_set_servers and mcp_message (in-process MCP servers), remote_control, channel_enable, ultrareview_launch, the claude_\/mcp_ auth subtypes, set_color, poll_event, stage_file, and agent-originated requests such as can_use_tool, hook_callback and elicitation.\n- Unrecognised request types get a generic \"is not supported in a cloud-hosted session\" rejection, recorded in telemetry as \"unknown\".\n\n**Evidence**\n\n`MCP server changes are not available in a cloud-hosted session yet; this machine's MCP servers reach cloud sessions through the device link`\n\n- Area: Cloud Sessions\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5"}
