Quantum OpenQASM MCP
Connects Claude to IBM Quantum hardware and simulators via the SamplerV2 REST API. You get five tools: list backends, submit OpenQASM 2.0 circuits, poll job status, retrieve measurement histograms, and cancel jobs. The server runs locally over stdio or remotely via SSE on IBM Code Engine. If you're prototyping quantum algorithms in an LLM chat and want to run them on real qubits without switching to Qiskit or the web console, this bridges that gap. Includes a VS Code extension with an interactive Quantum Lab panel, Bell and GHZ examples, and one-click MCP config generation for Cursor, Bob, and Antigravity.
