Each tool has a clearly distinct purpose: check_trust evaluates a server's score, evaluate_policy checks policy compliance, list_trusted searches for servers by criteria, and recommend provides natural-language recommendations. No overlap.

Tool names consistently use imperative verbs (check, evaluate, list, recommend) without nouns, which is a simple pattern. However, 'list_trusted' omits a noun like 'servers' for clarity, and the pattern could be slightly more descriptive, but overall consistent.

With only 4 tools, the scope is focused on trust evaluation and discovery. Each tool addresses a core need: score check, policy evaluation, search, and recommendation. No unnecessary tools, and the count feels appropriate for a trust-assessment server.

The tool surface covers key operations: retrieving trust scores, checking policies, searching, and recommending. Minor gaps might include batch operations or detailed audit logs, but the core functionality for trust assessment is well-covered.
