Qiskit Code Assistant MCP Server

Local MCP server that connects an assistant to the Qiskit Code Assistant for intelligent code completion, authenticated with an IBM Quantum API token.

What you can do

Provides intelligent code completion through the Qiskit Code Assistant, letting the assistant request completions for code it is working on. The API base URL and default completion model can be configured through environment variables. Authentication is handled with an IBM Quantum API token. No individual tools are listed in the manifest, so the exact operations are not documented here.

When to use it

Useful when working on Qiskit or quantum code and you want the assistant to draw on the Qiskit Code Assistant's completion service rather than a general model. Best suited to desktop setups where a local stdio process can be launched.

Requirements

Runs locally as a stdio process, launched with uvx from the qiskit-code-assistant-mcp-server PyPI package, so a Python/uv runtime is needed. Requires an IBM Quantum API token supplied in the QISKIT_IBM_TOKEN environment variable. Optional settings are QCA_TOOL_API_BASE for the API base URL and QCA_TOOL_MODEL_NAME for the default completion model. Network access to the Qiskit Code Assistant API is required.
