The MCP client entry (.mcp.json for Claude Code; see MCP setup). A read key is enough to browse; nothing here starts a robot.

Or hand the agent the task in words — the prompt names the tools and the exact commands.

You have the MouseMouse MCP server (lucen-mcp) configured against https://api.mousemouse.ai.
Work with the dataset repo lucen/laika-demo on that hub.
1. Read episodes with the dataset tools (list_episodes, get_episode_series) rather than downloading parquet.
2. Pull it locally only if you need the files: lucen pull lucen/laika-demo ./laika-demo.

README

laika-demo

A small teleoperation dataset for Laika v2: 3 episodes, 180 frames at 30 fps, 12 joint positions and 12 position targets per frame.

Synthetic placeholder. These frames were generated by make seed, not recorded on a robot — the trajectories are phase-offset sinusoids. The layout is a real LeRobotDataset v2.1 tree, so tooling that reads the real thing reads this too. It is replaced by the recorded dataset when that lands in assets/sample-dataset/.
