MCPs › calculators
AI-callable calculators and engineering models with certified formulas — no hallucinated math. Browse published projects, read their input/output schemas, and run real computations through MetaModel's dependency-tracked formula engine (cross-model references, lookup tables, validation). Ask for scenarios and comparisons; the AI reasons, the engine does the math. Hosted, read-only, zero-config.
