MCP (Model Context Protocol) server starter template for managing UI component registries
This is a bare-bones starter template with significant quality gaps. All three tools have empty input schemas ({}), no parameter descriptions, and minimal descriptions. Tool names are action verbs but vague. No output schemas documented. Error handling is present but generic. The server appears designed to fetch UI component metadata but lacks the structured definitions needed for LLM-guided tool selection.
Provides implementation details for another-component-basic, another-component-advanced components.
Provides implementation details for star-rating-basic, star-rating-fractions, upvote-rating-basic, upvote-rating-animated, face-rating-basic, face-rating-gradient components.
Provides a comprehensive list of all ui components.
All tools have empty input schemas ({}).
Tool descriptions are under 50 characters and lack context. 'Provides a comprehensive list of all ui components' (52 chars) is generic; no explanation of WHEN to call this tool vs alternatives, WHAT structure it returns, or dependencies.
Tool 'getAnotherSampleCateogory' has a typo in the name ('Cateogory' instead of 'Category'). This will confuse LLMs and violate naming clarity principles.
No output schema is documented for any tool. LLMs cannot plan downstream calls or extract the right fields. The code shows JSON.stringify(results) but no formal schema declaration.

Error handling is generic ('Failed to fetch components'). No recovery guidance. Does not tell LLM what to do next, which error is retryable, or what went wrong.
Tool composition: getRatings and getAnotherSampleCateogory appear to be statically registered via registerComponentsCategoryTools() based on categories in componentCategories. The actual components fetched are hardcoded, not user-selectable. This limits flexibility and prevents agents from discovering what components are available before requesting specific ones.
