Quantum Code Validator

Quantum Code Validator is an MCP server that provides static code validation and documentation lookups for quantum computing libraries. It connects Model Context Protocol clients like Claude Desktop directly to structured API definitions for PennyLane, covering releases from version v0.35.0 to v0.41.1. Quantum computing developers and AI coding agents use this server to inspect quantum algorithms before execution, ensuring that method names, arguments, and circuit constructions adhere to official library specifications. It executes static analysis via Python's built-in ast module and py_compile without running untrusted quantum workflows on hardware or simulators. The server exposes tools to evaluate custom code snippets against version-specific references and retrieve method documentation such as gate usage patterns directly inside agent environments. By catching compilation issues, invalid syntax, and deprecated API calls early, the tool helps developers maintain reliable quantum software architectures while designing hybrid quantum-classical algorithms.

1. Clone the repository and navigate into the directory: bash git clone https://github.com/Qyusu/quantum-code-validator.git cd quantum-code-validator 2. Create a virtual environment and install dependencies: bash python -m venv .venv source .venv/bin/activate curl -LsSf https://astral.sh/uv/install.sh | sh uv sync 3. Extract API definitions and format reference documents using the provided scripts: bash uv run scripts/parse_pennylane_api.py ./refdocs/pennylane/raw/v0.41.1.json uv run scripts/format_docs_by_llm.py v0.41.0,v0.41.1 4. Add the server entry to your client configuration file, such as claude_desktop_config.json: json { "mcpServers": { "quantum-code-validator": { "command": "uv", "args": [ "--directory", "/your/mcp/server/directory/quantum-code-validator", "run", "server.py", "--transport", "stdio" ] } } }

What you can do with Quantum Code Validator

• Validating PennyLane quantum circuits using static analysis against specific framework versions without executing operations on quantum hardware or simulators. - Retrieving detailed method signatures and usage patterns for PennyLane gates such as qml.CNOT directly inside LLM development environments. - Checking Python syntax and catching compilation errors in quantum algorithm scripts using standard ast and py_compile modules. - Auditing quantum computing codebases across multiple PennyLane releases to identify broken or deprecated library method implementations.
