FAQ

app.skillpack/public setup, tools, quality score, publishing readiness, and alternatives.

How do I add app.skillpack/public to Claude, ChatGPT, or Cursor?

Add app.skillpack/public to Claude, ChatGPT, or Cursor by connecting its remote MCP URL in each client's MCP settings. In Claude, add a custom connector. In ChatGPT, add an MCP app. In Cursor, add an MCP server under Settings. The MCP URL is https://skillpack.app/mcp/public.

Is app.skillpack/public MCP ready for ChatGPT and Claude?

As of November 11, 2026, app.skillpack/public scores 88/100 on Manufact's MCP publishing checklist. The scan does not yet meet ChatGPT publishing checks and does not yet meet Claude publishing checks. Passing these checks does not guarantee marketplace approval.

How clear is app.skillpack/public's MCP tool documentation?

As of November 11, 2026, app.skillpack/public scores 43/100 in Manufact's review of tool titles, descriptions, input and output schemas, and behavior annotations. The review covers 4 of 4 discovered tools. The quality score measures documentation clarity; runtime behavior and marketplace readiness require separate checks.

What are the best alternatives to app.skillpack/public?

As of November 12, 2026, alternatives to app.skillpack/public in search-research on the Manufact MCP leaderboard include TVFoodMaps, Search1API, Exa, Italian Strikes, and US Internet Serviceability.

How can app.skillpack/public improve its MCP documentation?

search_skills is the lowest-scoring reviewed tool at 41/100. 0 of 3 inputs have descriptions. Add descriptions to the missing inputs, including where to obtain IDs and how to supply values. Open its review for feedback and a copyable fix prompt, then rerun the documentation review after updating your tool metadata.
