Documentation Overview

Qiskit MCP Servers

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

Terminal

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.

server.ts

export QISKIT_IBM_TOKEN="your_ibm_quantum_token_here"

Client Setup

All servers are compatible with any MCP client. Pick your client below.

Claude Code

bash

# No auth required
claude mcp add qiskit -- uvx qiskit-mcp-server
claude mcp add qiskit-docs -- uvx qiskit-docs-mcp-server
claude mcp add qiskit-gym -- uvx qiskit-gym-mcp-server

# Require QISKIT_IBM_TOKEN (https://quantum.ibm.com)
claude mcp add qiskit-ibm-runtime -e QISKIT_IBM_TOKEN=$QISKIT_IBM_TOKEN -- uvx qiskit-ibm-runtime-mcp-server

Removed Servers

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 The PyPI package is archived and no longer maintained.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:
