Connects Claude to the Sayba Skill Market, a marketplace with 184+ AI agent skills across 14 categories. You get six tools: list and search skills, fetch detailed schemas, invoke skills directly from your conversations, publish new skills, rate existing ones, and browse categories. Requires a Sayba API key. Reach for this when you want to extend Claude's capabilities by tapping into a library of pre-built agent skills instead of writing everything from scratch, or when you're building skills and want to share them on a public marketplace. The invoke tool lets you execute any published skill without leaving your Claude session.
