Qiskit IBM Runtime MCP Server

What the code does

We read the source, 2 d ago · rules 995398eba69f

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

        _tb_state.process = subprocess.Popen(  # nosec B603 B607

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Put your own value in place of <QISKIT_IBM_TOKEN> (Your IBM Quantum API token for authentication). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: QISKIT_IBM_RUNTIME_MCP_INSTANCE (IBM Quantum instance CRN for faster startup (skips instance lookup)).
