If you're designing Phase 2 or Phase 3 trials, this gives Claude direct access to gsDesign, gsDesign2, and graphicalMCP through nine MCP tools. You get sample size calculations for binary, continuous, and time-to-event endpoints (both proportional hazards and non-proportional frameworks like MaxCombo and RMST), group sequential boundaries with configurable spending functions, and multiplicity adjustments including graphical procedures. The operational kernel solves accrual-duration-sample size relationships and flags feasibility violations. Monte Carlo verification cross-checks closed-form results, and the reporting tool exports to Word or PDF with citation chains. It's backed by 288 R tests and includes a benchmark corpus of 176 public trial designs for validation.
