Scored across 2 tools
The two tools are exactly opposite operations: one converts postal code to address, the other converts address to postal code. There is no overlap or ambiguity; an agent can clearly select the correct tool based on the input direction.
Both tools follow a consistent verb_noun pattern: lookup_zipcode and search_address. The verbs (lookup, search) are synonymous but acceptable, and the nouns clearly indicate inputs. Naming is uniform and predictable.
With only 2 tools, the count is at the lower edge of what might be considered thin, but the server's scope is deliberately narrow (bidirectional address/zip conversion). Both directions are covered, so the count is appropriate for the stated purpose.
The tool surface fully covers the domain of address-to-zip conversion: reverse lookup (zip→address) and forward lookup (address→zip). Both tools handle flexible input formats, making the functionality complete for the server's stated purpose.
