About

The official Model Context Protocol (MCP) server for the Boltz API. Predict molecular structures and binding interactions, screen small-molecule and protein libraries against a target, and design small molecules and protein binders — all from chat. Each workflow estimates cost before running, then downloads structured results to your workspace when the job completes.
