Qiskit IBM Runtime MCP Server
Connects Claude and other MCP clients directly to IBM's quantum computing infrastructure through Qiskit IBM Runtime. You get tools to list available quantum backends, check their properties and calibration data, submit circuits for execution on real quantum hardware or simulators, and retrieve job results. Requires a QISKIT_IBM_TOKEN from your IBM Quantum account. This is the server to use when you need to actually run quantum circuits on IBM's fleet rather than just simulate locally. Part of a larger Qiskit MCP collection that also includes transpilation, documentation search, and code generation servers, but this one specifically handles the runtime execution and backend management pieces.
