The tool name indicates value calculation based on existing healthcare data, which is consistent with Read operations. While the description is absent, the broader server context (semantic search, regulatory retrieval, data queries) and sibling tools (buscar_*, auditar_*, comparar_*) all point to information retrieval and analysis functions rather than data mutation or destructive actions.
