Scored across 1 tool
Disambiguation5/5
With only one tool, there is no possibility of confusion between tools. The tool's purpose is clearly defined and distinct from any hypothetical alternatives.
Naming Consistency5/5
The single tool name 'lookup_postal_code' follows a clear verb_noun pattern, and since there is only one tool, there are no inconsistencies or mixed conventions.
Tool Count2/5
The server offers only one tool, which feels too few for the broad scope of 'postal lookup'. A more complete set would at least include a reverse lookup (place to postal code) or validation, so the single tool is thin.
Completeness3/5
The tool covers the core function of resolving postal codes to places, but the description explicitly excludes reverse lookup and full address lookup, which are natural expectations for a postal lookup server. These gaps are notable but not catastrophic since the primary forward lookup is well implemented.
