mcp-servers: Instructions file for Codex

AGENTS.md

mcp-servers AGENTS.md is an instructions file for Codex, OpenCode from Qiskit/mcp-servers. It costs 11,715 tokens per session, scanned A, original, Apache-2.0.

Project instructions for a group of MCP servers that let AI assistants work with Qiskit and IBM Quantum services. Qiskit is software for creating and running programs on quantum computers.

In plain words
What is it for?
Use it when developing or maintaining quantum-computing tools, such as circuit execution, job management, code assistance, optimization, and conversion for quantum hardware.
Why use it?
It explains the project's architecture, technologies, and intended workflows so an agent can make compatible changes.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; mentions AGENTS.md.

This is Qiskit/mcp-servers's own configuration. It tells Codex and OpenCode how to work on mcp-servers itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-servers configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-servers AGENTS.md 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 2mo 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.

This file provides guidance to AI development assistants when working with code in this repository.

Supported AI Assistants:

  • IBM Bob
  • Claude Code
  • GitHub Copilot
  • Cursor AI
  • Windsurf
  • Gemini CLI
  • Any AI assistant with codebase context awareness

Project Overview

qiskit-mcp-servers is a collection of Model Context Protocol (MCP) servers that provide AI assistants, LLMs, and agents with seamless access to IBM Quantum services and Qiskit libraries for quantum computing development and research.

Core Purpose

  • Enable AI systems to interact with quantum computing resources through Qiskit
  • Provide production-ready MCP servers for quantum computing workflows
  • Connect AI assistants to real quantum hardware automatically
  • Simplify quantum circuit execution and job management
  • Provide intelligent quantum code completion and assistance
  • Enable AI-powered quantum circuit optimization and transpilation

Key Technologies

  • Protocol: Model Context Protocol (MCP)
  • Language: Python 3.10+ (3.11+ recommended)
  • Framework: FastMCP (async-first MCP framework)
  • Package Manager: uv (modern Python package manager with workspace support)
  • Testing: pytest with async support, 65%+ coverage
  • Code Quality: ruff (formatting + linting), mypy (type checking)
  • Build System: hatchling with pyproject.toml

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.
