simliverse-mcp AGENTS.md

simliverse-mcp AGENTS.md is an instructions file for Codex, OpenCode from SimLiverse/simliverse-mcp. It costs 1,323 tokens per session, scanned A, original, MIT.

Repository instructions for SimLiverse's experimental MCP server, which exposes NVIDIA Isaac Sim robotics actions to an AI agent. They cover the repository structure, its connection to upstream code, and networking restrictions.

In plain words
What is it for?
Use them when modifying, reviewing, or contributing to the simliverse-mcp repository and its Isaac Sim tools.
Why use it?
They give coding agents important project context and security-related constraints before changing the code. They also warn that the project is experimental and its interfaces may change.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

simliverse-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this repo is

simliverse-mcp is an experimental Model Context Protocol (MCP) server that exposes NVIDIA Isaac Sim as a set of tool-callable actions (scene setup, robot/object creation, sensors, lighting, materials, action graphs, simulation stepping, etc.). The tool implementations live in isaac_mcp/tools/, the MCP entry point is isaac_mcp/server.py, the transport/connection layer is isaac_mcp/connection.py, and the Isaac Sim-side extension that the server talks to is isaac.sim.mcp_extension/.

This repo is currently under experiment. It is not a finished, stable product. The longer-term goal is an AI agent for SimLiverse that includes a sub-agent for managing Isaac Sim; this repo is the test bed for building the Isaac Sim MCP server half of that. Expect churn in tool names, arguments, and behavior.

Relationship to upstream and to simliverse-core

  • This repo is a fork of the external upstream project whats2000/isaacsim-mcp-server. General contribution norms (dev environment setup, PR process, code style, project layout) are inherited from that upstream project — see CONTRIBUTING.md for those details rather than duplicating them here.
  • This server is consumed by simliverse-core, specifically api/app/services/mcp_bridge.py, which resolves the private VPC IP of a job's worker VM and talks to this server's /mcp endpoint using MCP JSON-RPC 2.0. The integration is documented (as of this writing) in simliverse-core/docs/adr/010-isaacsim-copilot-mcp-bridge.md (relative path in the sibling simliverse-core repo — not guaranteed to be readable from here, check if it exists before relying on it).
  • The agent harness in simliverse-core that drives this MCP server currently doesn't work well at all. simliverse-core's own ARCHITECTURE.md (§9) explicitly flags that "the MCP tool-call contract between this bridge and simliverse-mcp is unstable" and recommends investigating that contract before expanding further. Anyone picking up work here should expect to dig into that integration rather than assume it's solid.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
