Review an MCP (Model Context Protocol) server for tool-design quality: tool naming and granularity, description/annotation accuracy, input schema strictness, output token budgets, error handling, and role/permission safety. Produces a prioritized findings list, not a rewrite. Use when reviewing, auditing, or hardening an MCP server or its tool definitions. Triggers on: review my MCP server, audit MCP tools, MCP tool design, are my tool descriptions good, MCP server quality.
