moco-mcp is a well-intentioned read-only component registry server with clear naming and solid descriptions. All 5 tools follow verb_noun convention (list_, search_, get_). Descriptions are substantive (100-250 chars), explaining WHAT and WHEN. Tool annotations (readOnlyHint) are correctly applied. However, input schemas are minimal: list_components and get_theme have empty objects ({}), search_components uses Zod but schema visibility in output is unclear, and get_component uses enum but lacks detailed parameter docs. Output schemas are not formally documented, responses are text-wrapped JSON without declared field contracts. Error handling is absent: no guidance on invalid component names, missing registry, or malformed queries. Composition is sound (each tool has one job), but the server lacks pagination, result limits, and structured output contracts that production tools require.

• Declare explicit output schemas for all tools. E.g., list_components returns {items: [{name, title, description, tags}]}, search_components returns {results: [...], total_count, query}. Document these in tool descriptions or as structured comments.
• Add error handling to get_component: catch invalid names and return 'Component "xyz" not found. Available: [list]. Try search_components("xyz") for partial matches.'
• Add pagination to search_components: accept optional limit (default 20, max 100) and offset parameters. Return {results, total_count, offset, limit} so LLMs can iterate.
• Enhance get_component description to explain the enum constraint: 'name must be one of the component names returned by list_components() or search_components().'
• Document the structure of files, dependencies, and registryDependencies in get_component's description so LLMs know what fields to expect and how to process them.
