Overview

An MCP server for running, sharing, and editing quantum circuits written in OpenQASM 3.x, backed by the Quasar quantum simulator.

Installation

Run Command
go run main.go

Environment Variables

  • IDENTITY_TOKEN
  • TARGET_URL
  • PORT

Security Notes

The server fetches grammar files (`.g4`) from hardcoded GitHub URLs using `HttpGet`. While these URLs are fixed and appear benign, performing HTTP requests within resource handlers could potentially be a vector for abuse if URLs were dynamic or user-controlled. However, in this implementation, the URLs are static. Sensitive credentials (`IDENTITY_TOKEN`, `TARGET_URL`) are correctly loaded from environment variables, which is a good security practice. No `eval` or obvious obfuscation detected.
