M14.1: MCP server + agent CLI
- crates/automation (L5, no egui): hand-rolled JSON-RPC 2.0 MCP server over
stdio (initialize, ping, tools/list, tools/call); headless backend (in-process
Session) and bridge backend (desktop control channel). Tools: list_commands,
execute_command, get_project/comp/layer, get/set_property, add_keyframe,
render_frame (inline PNG), open/save_project, undo/redo; bridge-only
screenshot, ui_* and raw control passthrough.
- effectcraft-cli: info, commands, exec, run, props, get, set, render-frame,
mcp [--bridge PORT]; --json, --project/--demo/--empty, --save/--save-as.
- engine: prop.get, layer.tree node paths + time, Session::resolve_comp,
render_rgba8, execute_checked (rejects unknown params, lists accepted keys).
- control channel: render.frame; engine.execute runs every engine command
directly (no dialogs, validated params).
- docs: control-protocol.md, agents.md.
