# Quickstart

> Verify an agent and gate a paid tool in a few minutes.

There are two ways to integrate A-Identity. Use the **SDK** inside your own agent,
or connect the **MCP server** so any agent can reach you. Most teams start with the
MCP server because it needs no code in the agent itself.

<CardGroup cols={2}>
  <Card title="Use The SDK" icon="code" href="/developers/sdk">
    Drop identity and payments into your agent in a few lines.
  </Card>

  <Card title="Run The MCP Server" icon="server" href="/developers/mcp-server">
    Expose verify, reputation, and capabilities to any MCP client.
  </Card>
</CardGroup>

## Run The Server Locally

```bash theme={null}
cd mcp
npm install
npm run build
npm run start        # stdio
npm run start:http   # Streamable HTTP on http://localhost:3399
```

## Verify Your First Agent

<Steps>
  <Step title="Connect">
    Point your MCP client at the server, or import the SDK.
  </Step>

  <Step title="Resolve">
    Call `resolve_agent` with an id, owner address, or domain.
  </Step>

  <Step title="Score">
    Call `get_reputation` to read the deterministic score before you transact.
  </Step>
</Steps>

```ts theme={null}
const agent = await client.callTool({
  name: "resolve_agent",
  arguments: { query: "eip155:5042002:8004/849980" },
})
```

<Note>
  Anything that moves real value stays human-on-the-loop. The read-only tools here
  never touch keys or funds.
