mcp-meupc is a STDIO-only server with 6 well-defined read-only tools targeting the Brazilian PC component marketplace (meupc.net). Tool naming follows verb_noun conventions consistently (search_*, list_*, get_*). All tools have descriptions (mean ~110 chars, within baseline 34-392 range). Input schemas use Zod with type definitions and parameter descriptions present. However, output schemas are NOT documented, responses are plain text only, lacking structured field documentation that LLMs need for downstream reasoning. Parameter descriptions are functional but generic (e.g., 'Número da página' vs actionable constraints). No error handling guidance, no pagination documentation in tool descriptions despite accepting page params, and no mention of result limits or API rate considerations. The server is architecturally sound for read-only web scraping but falls short of production-grade tooling patterns in schema completeness, error recovery, and composition clarity.

• Document output schemas for all 6 tools. Define structured return objects (e.g., search_components returns {components: [{name, price, url, specs}], total_results, page, page_size}) and include this in tool descriptions so LLMs know what fields to expect.
• Add error handling and recovery guidance. Update descriptions to note: 'If component not found, try search_components() with a broader query.' Return error objects with actionable messages instead of raw HTTP status strings.
• Complete pagination documentation. For list_components, get_deals, list_community_builds: add 'Returns X results per page. Use page param to iterate. Total results returned in response.' Document any hard limits (e.g., max 50 items per page).
• Add input validation constraints to parameter descriptions. E.g., 'limit: integer, 1 - 50 (defaults to 10). Requests exceeding 50 will be capped.' Similarly, 'sort: one of melhores-recentes|melhores|novas; defaults to melhores-recentes.'
• Refactor responses from plain text to structured JSON. Use the response-shaper pattern: instead of returning a raw HTML-parsing output, return {components: [...], build_details: {...}, deals: [...]} with typed fields. This enables LLM composition and error recovery.
• Add rate-limiting or rate-limit warnings to tool descriptions. The scraper has no rate limiting; add guidance like 'Avoid calling search_components more than 10 times per minute to prevent IP blocking.'
• Separate discovery and detail tools more explicitly. get_component_details requires a URL (from search_components), but the dependency is implicit. Add a note: 'Call search_components first to obtain component URLs, then pass them to get_component_details.'
