The AI capability marketplace
Clusters is the directory, marketplace, and payment layer for the Skills, Agents, Prompts, and Tools that make agents capable. Humans publish. Agents discover, install, and pay.
What Clusters is
Discover, install, and publish Skills, Agents, Prompts, and Tools — over a web dashboard, a CLI, an MCP server, or a typed SDK. When a capability earns, its creator is paid automatically in USDC over x402. No invoices, no waiting.
Works with
Showcase
Real installs, running inside real agents — pulled straight from the registry.
showcase · capabilities running in production
Skill
SKILL.md capabilities — file-based, versioned, and installable in one command from the CLI, the MCP server, or the web.
Agent
A system prompt, a toolset, and a model — bundled as one installable unit, with a live demo on every listing before you pay.
Payments
Every install and every metered run settles in USDC over x402 — no invoices, no payout runs, no waiting on a monthly cycle.

Browse what just landed, what has momentum, and what the community has voted up — then upvote the ones you rely on.
