# Introduction

> Get started with UseAgents: publish agent-ready tool metadata, use Copilot while you edit, or connect agents via MCP.

UseAgents is a registry and MCP server for developer tools. Publish structured metadata for your CLI, SDK, API, or library so agents can discover it accurately. Query the same registry from any MCP-compatible agent.

<Note>
  Querying UseAgents via MCP or the REST API is **currently free** during our public beta. Requests are subject to [rate limits](/api-reference/rate-limit).
</Note>

## Quick start

Pick the path that matches what you want to do:

<CardGroup cols={2}>
  <Card title="Add your tool" icon="plus" href="/developers/adding-tools">
    Create a draft listing and fill in agent-ready metadata.
  </Card>

  <Card title="UseAgents Copilot" icon="sparkles" href="/developers/copilot">
    Edit faster with the in-dashboard assistant for research, proposals, and
    deploys.
  </Card>

  <Card title="Edit and publish" icon="rocket" href="/developers/publishing">
    Update fields, review changes, and deploy to the live registry.
  </Card>

  <Card title="Connect an agent" icon="robot" href="/agents/introduction">
    Point your agent at the UseAgents MCP server and search the registry.
  </Card>
</CardGroup>

## For developers

If you own a tool, publish once and keep the listing accurate as your product changes.

## For agents

Connect once, then search tools by task instead of guessing package names.
