Question 1

What is an AI agent registry?

Accepted Answer

An AI agent registry is a directory where developers can discover, share, and copy ready-to-use AI agents. 21st.dev separates 21st SDK agents from cloud-managed agent configs, then lets developers choose YAML, JSON, TypeScript, CLI, or Python where supported.

Question 2

How do I use agents from the registry?

Accepted Answer

Browse the registry, find an agent that fits your use case, choose either the 21st SDK runtime or the cloud-managed runtime, then copy the code format you need.

Question 3

What are cloud-managed agents?

Accepted Answer

Cloud-managed agents are configuration-backed agents meant to run on hosted infrastructure. The 21st.dev registry presents them as a separate runtime path from 21st SDK source agents.

Question 4

What are MCP servers?

Accepted Answer

MCP (Model Context Protocol) servers provide tools and capabilities to AI agents. They enable agents to interact with external services like GitHub, Slack, databases, and more. Agents in the 21st.dev registry come pre-configured with MCP servers.

Question 5

Can I publish my own AI agent?

Accepted Answer

Yes! Anyone can publish their agent configuration to the 21st.dev registry. Share your YAML or JSON config and the community can discover, copy, and remix your agent.
