Install Isaac Sim robot workbench in Devin Desktop

What you need first

• Devin Desktop, installed.
• uv, which gives the uvx command the server starts with.
• Your own value for YOUR_ISAAC_MCP_HOME.

Steps

1. Open ~/.config/devin/mcp_config.json, or create it. On Windows it is %APPDATA%\devin\mcp_config.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "dex-isaac-mcp": {
      "command": "uvx",
      "args": ["dex-isaac-mcp==0.1.2"],
      "env": { "ISAAC_MCP_HOME": "YOUR_ISAAC_MCP_HOME" }
    }
  }
}

3. Replace YOUR_ISAAC_MCP_HOME with your own value.
4. Save the file and restart Devin Desktop.

Check it worked

Ask Devin Desktop: List the tools of dex-isaac-mcp.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that Devin Desktop sees. Install it, or write the full path of uvx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
