# Agent Skills

> Install Money Dev Kit skills for coding agents

Money Dev Kit agent skills teach coding agents how to add Lightning payments to your app. Use them to set up checkout, connect the MCP server, build L402 paid APIs, and work with the Money Dev Kit agent wallet.

<Info>
  Skills give your agent reusable Money Dev Kit implementation guidance. For live account and app operations, use the [Money Dev Kit MCP server](/nextjs#install-with-ai-coding-tools) alongside these skills.
