quantum-openqasm-mcp

quantum-openqasm-mcp is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from markusvankempen/quantum-openqasm-assistant. Its token cost is not measured, scanned A, original, Apache-2.0.

A local MCP tool for IBM Quantum that lists quantum-computing backends, submits OpenQASM 2.0 programs, checks job progress, and returns result histograms.

In plain words
What is it for?
Choosing a quantum backend, running QASM circuits, monitoring submitted jobs, and viewing measurement distributions. It requires four IBM Quantum environment variables.
Why use it?
It lets a coding agent send quantum programs to IBM Quantum and inspect their results from one tool.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

quantum-openqasm-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
