# OpenClaw MCP setup

> Native remote MCP configuration, browser authorization, tool verification, and troubleshooting

This page covers native MCP in OpenClaw. The remote service uses Streamable HTTP and browser OAuth without requiring EvoLink CLI. For command and skill execution, use the separate [CLI guide](/docs/en/cli/openclaw).

## Connect remote MCP

For native tools, use **Streamable HTTP + OAuth** with this server URL:

```text theme={null}
https://mcp.evolink.ai/mcp
```

CLI installation is not required. Back up existing configuration, merge only EvoLink, and preserve other services. Choose command-based or manual registration.

<Steps>
  <Step title="Check remote MCP support">
    ```bash theme={null}
    openclaw mcp --help
    ```

    The actual Gateway version needs Streamable HTTP and OAuth support. If these commands are absent, follow that version’s upgrade guidance or use the [separate CLI guide](/docs/en/cli/openclaw); do not invent flags for an older host.
  </Step>

  <Step title="Add the server and set OAuth">
    ```bash theme={null}
    openclaw mcp add evolink --url https://mcp.evolink.ai/mcp --transport streamable-http
    ```

    In the Gateway’s `~/.openclaw/openclaw.json` or actual configuration, set `auth` to `"oauth"` within `mcp.servers.evolink`, preserving other generated fields. Supported Control UI versions can add and enable it under Settings → MCP.
  </Step>

  <Step title="Authorize, probe, and query">
    ```bash theme={null}
    openclaw mcp login evolink
    openclaw mcp doctor evolink --probe
    ```

    After browser approval, use the agent owned by the actual Gateway to send the prompt below. Refresh the Gateway that owns the connection when changes are not reflected; refreshing a laptop terminal does not refresh a remote Gateway.
  </Step>
</Steps>

OpenClaw’s tool policy also controls availability. See [OpenClaw documentation](https://docs.openclaw.ai/tools/mcp) for version, authorization, and connection ownership.

After authorization, send this in the agent chat:

```text theme={null}
Use EvoLink to check my account balance and search available image models. Do not generate anything yet.
```

**Success:** actual `check_balance` and `search_models` calls return results. Verify these tools in the actual MCP connection.

## Updates, disconnection, and troubleshooting

EvoLink updates the hosted MCP server. Refresh the actual client session after configuration changes. Reauthorize through that client's OAuth action when needed. Disable, sign out, or remove EvoLink in host MCP settings to disconnect; retain other servers.

| Symptom | Action |
| - | - |
| URL added but no tools | Enable the connection, complete authorization, refresh, and check organization policy |
| 401 or authentication required | Reauthorize this MCP connection and retain original task IDs |
| 403 or tool denied | Check host permissions, account/Key status, and network errors |
| Timeout or lost response | Query and recover the original operation instead of regenerating |
| Link-only or gray preview | Open and deliver the original without automatically remaking it |

See [MCP costs, access, and troubleshooting](/docs/en/mcp/billing#faq). Read the [creation workflow](/docs/en/mcp/overview#workflows) before submitting; call shapes are in the [MCP tool reference](/docs/en/mcp/tools).
