From the project's README
As published by jiankn/nbmecalc-mcp in README.md.
A remote Model Context Protocol server exposing deterministic, offline practice-assessment conversions for integrations that complement the USMLE score predictor.
The Streamable HTTP endpoint is /mcp. The server exposes
convert_practice_score and returns the estimate together with the v1.1
algorithm identifier and a required disclaimer.
It has no database, account system, analytics call, or learner-data storage. Mappings are independent model assumptions, not official conversions or examination guarantees. Do not use outputs for clinical decisions.
