What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

            process = subprocess.Popen(

            module = __import__(f"multisim_mcp.{module_name}", fromlist=["run_natural_engineering"])

        worker_env = dict(os.environ)

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

claude mcp add multisim-mcp -- uvx multisim-mcp

    "multisim-mcp": {
      "args": [
        "multisim-mcp"
      ],
      "command": "uvx"
    }
  }
}

[mcp_servers.multisim-mcp]
command = "uvx"
args = ["multisim-mcp"]

This one needs environment variables set before it will start: MULTISIM_MCP_TEMPLATE_DIR (User-local template pack generated from a licensed Multisim installation.). The author declared them in the registry entry; get the values from the project itself.
