Quantum OpenQASM MCP tools (10, 2 write)
write = sends, deletes, buys or postsRead from the package source without running it. The installed server may list more.
cancel_jobwrite actionCancel a queued or running quantum job.
check_credentialsCheck which IBM Quantum env vars are set (masked) and test IBM IAM connectivity.
get_backendGet details for a specific IBM Quantum backend by name.
get_backend_configurationGet gate set and coupling configuration for a backend (useful for ISA circuit prep).
get_job_resultGet job status and results in one call (legacy combined tool).
get_job_resultsGet measurement results from a completed quantum job.
get_job_statusGet the current status of a quantum job without fetching full results.
list_backendsList available IBM Quantum backends with name, status, and qubit count.
list_jobsList recent quantum jobs submitted by this account.
submit_qasm_jobwrite actionSubmit an OpenQASM 2.0 ISA circuit to IBM Quantum hardware via SamplerV2.

Install Quantum OpenQASM MCP in Claude Code, Cursor or VS Code
Runs npx -y @markusvankempen/quantum-openqasm-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Overview
Quantum OpenQASM Assistant connects AI agents and developers to IBM Quantum through a pure TypeScript MCP server and VS Code extension. Submit OpenQASM 2.0 ISA circuits, poll job status, and view measurement histograms — locally via stdio or remotely via SSE on IBM Code Engine.
