FlagQuantum MCP Server

The FlagQuantum MCP Server provides AI assistants, agents, and IDEs with direct access to the FlagQuantum SDK. It enables users to build, compile, route, serialize, and plan quantum circuits locally. The server operates without requiring credentials or outbound network access, relying on the local FlagQuantum SDK for execution.
