Scored across 1 tool
Only one tool exists, so there is no possibility of confusion between tools. The tool's purpose is clearly defined as a web search operation.
The single tool name 'yacy_search' is descriptive and follows a verb-like pattern, but with only one tool there is no pattern to compare against for consistency.
A single search tool is too few for a full-featured MCP server, even one focused on a single search engine. Users would expect additional capabilities like managing resources or getting engine status.
The search tool provides the core search functionality, but lacks any supporting operations such as retrieving specific results, filtering, or examining engine state. This leaves significant gaps for agents that might need more than a basic search.
