# Connecting the MCP Server

> Connect the UseAgents MCP server to Cursor, Claude, Windsurf, Antigravity, Codex, v0, and other MCP-compatible agents.

Connect the UseAgents MCP server to your agent so it can search the UseAgents registry for verified tools. After setup, your agent can use natural language to find real SDKs, APIs, CLIs, and libraries instead of guessing.

<Note>
  Querying UseAgents via MCP is **currently free** during our public beta. No API key is required. Requests are subject to [rate limits](/api-reference/rate-limit) to ensure reliability.
</Note>

## Connection details

| Setting | Value                            |
| ------- | -------------------------------- |
| **URL** | `https://mcp.useagents.site/mcp` |

## Add the server to your agent

Add the UseAgents MCP server to your agent's configuration. No authentication headers are needed during the public beta.

### Quick config

Any MCP client that supports HTTP transport can use this configuration:

```json theme={null}
{
  "mcpServers": {
    "UseAgents": {
      "url": "https://mcp.useagents.site/mcp"
    }
  }
}
```

## Verify the connection

After saving the config and restarting your client:

1. Open your MCP-compatible agent.
2. Confirm the `UseAgents` server appears in the MCP server list, if your client shows one.
3. Ask the agent to search for a tool such as "find a TypeScript SDK for Stripe webhooks" using `search_tools`.
4. Confirm the response includes structured tool results rather than a connection error.

## Troubleshooting

* **Server does not appear**: Restart the MCP client after editing the config file.
* **Requests fail unexpectedly**: Re-copy the URL exactly as `https://mcp.useagents.site/mcp` and remove extra whitespace or trailing characters.
* **Rate limited**: You have exceeded the request limit. Wait a moment and try again. See [Rate Limits](/api-reference/rate-limit) for details.
