get_isaac_sim_instructions- Top-level guidance on Isaac Sim development.
search_isaac_sim_extensions- Semantic search across the indexed Isaac Sim extension catalog.
get_isaac_sim_extension_details- Full details for one or more extensions.
search_isaac_sim_code_examples- Find Isaac Sim code patterns by description.

As documented on October 17, 2026. A running server reports its current list through tools/list.
Notes and caveats
- Runs locally and serves Streamable HTTP at
http://localhost:9904/mcp. - Requires NVIDIA_API_KEY for hosted embeddings, reranking and LLM calls.
- The README mentions a previously hosted isaac-sim-mcp endpoint only in the context of resolving name collisions; the documented setup is self-hosted.
