What are the best Claude skills for backend development?
Right now the top-ranked backend skills on Alyn are MCP Builder (Anthropic), Backend Patterns (affaan-m), API And Interface Design (Addy Osmani). Rankings combine GitHub stars, installs, freshness and depth, and update live.
Is there an official Supabase skill?
Yes. supabase/agent-skills is published by Supabase and ranks among the most installed backend skills.
Skills or MCP for databases?
Use both. An MCP server gives the agent access to your database. A skill teaches it how to use that access well.
How do I install a backend skill?
Run npx skills add owner/repo in your project, or copy the folder with SKILL.md into ~/.claude/skills. Every skill on this page has a ready-to-copy command.
