Scored across 5 tools
Each tool has a clearly distinct role in the proxy workflow: search_tools discovers tools, describe_tool returns schemas, call_read_tool and call_read_tools execute single vs batch read-only calls, and call_write_tool executes mutating calls. The singular/plural read pair is the only close pair, but their batch-vs-single distinction is explicit in the descriptions.
All names follow a consistent snake_case verb_noun pattern: search_tools, describe_tool, call_read_tool, call_read_tools, call_write_tool. The plural suffix on call_read_tools is a readable and intentional variation for batching.
Five tools is well-scoped for a proxy server whose job is to discover, inspect, and invoke other tools. Each tool earns its place, with no redundant surface area.
The surface covers discovery, schema inspection, single and batch read execution, and write execution, which are the core operations for this proxy domain. Minor gaps include no batch write operation and no explicit enumerate-all-tools call, though search_tools can approximate discovery.
