License listed as Apache-2.0
⚠️ Limitations
The provided server data includes limited details beyond the description and repository badges; features beyond intelligent code completion are not specified
A collection of Model Context Protocol (MCP) servers that give AI assistants, LLMs, and agents seamless access to IBM Quantum services and Qiskit libraries. Generate quantum code, connect to real hardware, analyze backends, execute circuits, and search Qiskit documentation — all through a standardized protocol that works with any MCP-compatible client.
Quick Start
Prerequisites
Python 3.10+ (3.11+ recommended)
IBM Quantum account and API token (only required for IBM cloud servers: Runtime, Transpiler)
Install from PyPI
bash
# Install all servers (core + community)
pip install "qiskit-mcp-servers[all]"# Install core servers only (default, excludes community)
pip install qiskit-mcp-servers
Install individual servers
bash
pip install "qiskit-mcp-servers[qiskit]"# Qiskit server only
pip install "qiskit-mcp-servers[runtime]"# IBM Runtime server only
pip install "qiskit-mcp-servers[transpiler]"# IBM Transpiler server only
pip install "qiskit-mcp-servers[docs]"# Documentation server only
pip install "qiskit-mcp-servers[gym]"# Qiskit Gym server only (community)
Install from Source
Each server runs independently — the directory name and command are the same:
bash
cd qiskit-mcp-server # or any server directory
pip install -e .
qiskit-mcp-server
Configuration
Servers that connect to IBM Quantum cloud services require a QISKIT_IBM_TOKEN environment variable. See each server's README for the full list of environment variables and configuration options.

Qiskit Code Assistant MCP Server — previously published as qiskit-code-assistant-mcp-server. Removed because the underlying Qiskit Code Assistant service has been discontinued by IBM Quantum. See the sunset announcement. The PyPI package is archived and no longer maintained.
Examples
Each server includes an examples/ directory with a Jupyter notebook (langchain_agent.ipynb) and a Python script (langchain_agent.py) showing how to build AI agents with LangChain.
The root examples/ directory contains a multi-agent Quantum Volume Finder that orchestrates multiple MCP servers to find the highest achievable Quantum Volume on IBM Quantum hardware. See the examples README for details.
Architecture
All servers are built on FastMCP and share a consistent structure:
Async-first — all tool and resource handlers are async, using FastMCP's native async support
Standalone packages — each server is an independent PyPI package with its own pyproject.toml, tests, and CI
MCP Registry — every server ships a server.json manifest for automatic discovery
Unified meta-package — qiskit-mcp-servers installs any combination via pip extras
Full MCP protocol — tools (quantum operations), resources (backend info, service status), and stdio transport
Development
Running Tests
bash
cd qiskit-mcp-server # or any server directory
./run_tests.sh
Code Quality
Linting: ruff check and ruff format
Type checking: mypy src/
Testing: pytest with async support and coverage reporting
