Qiskit MCP server

mcp-qiskit

MCP server exposing Qiskit 2.3.1 quantum computing functionality through the Model Context Protocol. Enables LLMs to create, manipulate, and execute quantum circuits via standardized MCP tools and resources.

mcp-name: io.github.daedalus/mcp-qiskit

Overview

This project provides a Model Context Protocol (MCP) server that exposes Qiskit quantum computing functionality to Large Language Models (LLMs). It allows AI assistants to:

• Create and manipulate quantum circuits
• Execute circuits on quantum simulators or real backends
• Analyze circuit properties (depth, gates, operations)
• Visualize circuits in various formats
• Manage quantum backends

Why Use This?

• LLM Integration: Enables AI assistants to perform quantum computing tasks without external tooling
• Standardized Interface: MCP provides a consistent tool-based interface for quantum operations
• Qiskit 2.3.1 Compatible: Specifically designed for Qiskit 2.3.1 with all its features
• Extensible: Easy to add new tools or backends

Installation

Prerequisites

• Python 3.11 or higher
• Qiskit 2.3.1
• A running MCP client (Claude Desktop, Cursor, etc.)

Install from PyPI

pip install mcp-qiskit[qiskit]

The [qiskit] extra installs the required Qiskit dependencies. Other extras available:

# Install with development dependencies
pip install mcp-qiskit[dev,test]

# Install with MCP server dependencies
pip install mcp-qiskit[mcp]

Install from Source

git clone https://github.com/daedalus/mcp-qiskit.git
cd mcp-qiskit
pip install -e ".[all]"

Quick Start

As a Python Library

from mcp_qiskit import create_quantum_circuit, add_gate, add_gates, add_measurement, run_circuit

# Create a 2-qubit circuit with 2 classical bits
circuit = create_quantum_circuit(2, 2)

# Apply a Hadamard gate on qubit 0
circuit = add_gate(circuit, "h", [0])

# Apply CNOT gate (control: qubit 0, target: qubit 1)
circuit = add_gate(circuit, "cx", [0, 1])

# Or add multiple gates at once with add_gates
circuit = add_gates(circuit, [
    {"gate": "h", "qubits": [0]},
    {"gate": "cx", "qubits": [0, 1]},
])

# Measure all qubits
circuit = add_measurement(circuit, [0, 1])

# Execute on Aer simulator
result = run_circuit(circuit, "aer_simulator", shots=1024)
print(f"Measurement results: {result['counts']}")

As an MCP Server

Claude Desktop

Add to your claudedesktopconfig.json:

{
  "mcpServers": {
    "mcp-qiskit": {
      "command": "mcp-qiskit",
      "env": {}
    }
  }
}

Cursor

Add to your Cursor settings under MCP Servers:

{
  "mcpServers": {
    "mcp-qiskit": {
      "command": "mcp-qiskit",
      "args": []
    }
  }
}

Other MCP Clients

# Run as stdio server
mcp-qiskit

# Or use the Python module directly
python -m mcp_qiskit

MCP Tools Reference

Circuit Creation Tools

createquantumcircuit_tool

Creates an empty quantum circuit with specified number of qubits and classical bits.

Parameters:

• num_qubits (int): Number of quantum bits
• numclassicalbits (int): Number of classical bits for measurements

Returns: Dictionary representing the circuit

Example:

circuit = create_quantum_circuit_tool(num_qubits=3, num_classical_bits=3)
