Isaacsim MCP Server

Connect any MCP-compatible IDE (Cursor, VS Code, Claude Code, Windsurf, Antigravity, JetBrains) to a running Isaac Sim instance and control it with plain-English prompts -- create robots, build scenes, run simulations, and debug physics all from your editor. It runs locally over stdio via the published package.

People who work with Isaac and Isaacsim and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

Claude Code

claude mcp add whats2000-isaacsim-mcp-server -- uvx isaacsim-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "whats2000-isaacsim-mcp-server": {
      "command": "uvx",
      "args": [
        "isaacsim-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
