Metadata
Computed from the server's own data, not a hidden formula. This measures how much you can depend on it, not how popular it is. Stars are shown separately, on purpose. How it's scored →
▸validate_invoice100A
▸extract_xml100A
▸check_consistency100A
▸create_invoice100A
Structural, not an LLM's opinion: each check is a fact about the tool's schema, so it's reproducible. One weak tool drags the score (60% average, 40% worst). How it's scored →
