SimLiverse MCP Server (simliverse-mcp)

The unified Model Context Protocol (MCP) server for the SimLiverse Physical AI Platform.

It provides a minimal, clean 10-tool interface to LLM Copilots:

  • 5 Knowledge/RAG tools (NVIDIA NIM cloud) — look up Isaac Sim Python API documentation and code examples.

  • 5 Execution/Telemetry tools (Isaac Sim TCP socket on port 8766) — execute code, play/pause physics, inspect USD scene state, and read joint telemetry.

Available Tools (10 Total)

šŸ“š Knowledge & RAG (NVIDIA NIM)

  1. get_isaac_sim_instructions: Read official Isaac Sim developer guide topics.

  2. search_isaac_sim_code_examples: Find working Python code snippets for Isaac Sim 5.1.0.

  3. search_isaac_sim_extensions: Discover Omniverse extensions by capability.

  4. get_isaac_sim_extension_details: Inspect extension API specifications.

  5. search_isaac_sim_settings: Search physics engine and rendering config keys.

šŸ¤– Execution & Control (Isaac Sim Extension via TCP :8766)

  1. execute_script: Run Python code inside the live Isaac Sim stage runtime.

  2. set_simulation_state: Play, pause, stop, or step physics frames.

  3. reset_scene: Clear the USD stage and reset to initial state.

šŸ‘ļø Telemetry & Sensing

  1. get_scene_info: Inspect stage prims, positions, asset root, and prim counts.

  2. get_joint_states: Read joint positions, velocities, and limits for any robot prim.
