Nothing serious here today

Today is the operative word: we check FlagQuantum MCP Server every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: FLAGQUANTUM_MCP_MAX_QUBITS (Largest circuit width the server will process. Defaults to 24.), FLAGQUANTUM_MCP_MAX_GATES (Largest instruction count the server will process. Defaults to 10000.), FLAGQUANTUM_MCP_MAX_IR_BYTES (Largest serialized circuit payload accepted, in bytes. Defaults to 262144.). The author declared them in the registry entry; get the values from the project itself.

FlagQuantum MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for FlagQuantum MCP Server?

FlagQuantum MCP Server runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package flagquantum-mcp-server.

How do I connect FlagQuantum MCP Server?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls flagquantum-mcp-server straight from pypi; nothing to host, nothing to sign up for.

Is FlagQuantum MCP Server open source?

Yes — it is published under the Apache-2.0 licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
