# Zed

[<mark style="color:blue;">Zed</mark>](https://zed.dev) is a high-performance code editor with built-in MCP support. Zed uses a `context_servers` configuration key rather than `mcpServers`.

## Prerequisites

* Zed installed. For more information, see [<mark style="color:blue;">zed.dev</mark>](https://zed.dev)
* The `ionoscloud-mcp` binary built and available. For more information, see [<mark style="color:blue;">Quick Start</mark>](/cloud/ai/mcp-server/quick-start.md)
* An <code class="expression">space.vars.ionos\_cloud\_api</code> token. For least-privilege access, see [<mark style="color:blue;">Authentication</mark>](/cloud/ai/mcp-server/configuration/authentication.md#token-scope-by-product-area) to scope the token to only the tools you need.

## Add the MCP server

Open or create `~/.config/zed/settings.json` and add a `context_servers` block:

```json
{
  "context_servers": {
    "ionoscloud": {
      "source": "custom",
      "command": {
        "path": "/usr/local/bin/ionoscloud-mcp",
        "args": [],
        "env": {
          "IONOS_TOKEN": "your-api-token"
        }
      }
    }
  }
}
```

To also enable Object Storage tools:

```json
{
  "context_servers": {
    "ionoscloud": {
      "source": "custom",
      "command": {
        "path": "/usr/local/bin/ionoscloud-mcp",
        "args": [],
        "env": {
          "IONOS_TOKEN": "your-api-token",
          "IONOS_S3_ACCESS_KEY": "your-access-key",
          "IONOS_S3_SECRET_KEY": "your-secret-key"
        }
      }
    }
  }
}
```

{% hint style="info" %}
**Note:** Zed uses `context_servers` (not `mcpServers`) and wraps the command in a `command` object with `path`, `args`, and `env` fields. The structure differs from other MCP clients.
{% endhint %}

## Verify the connection

{% stepper %}
{% step %}

### Reload Zed

Save the settings file. Zed picks up context server changes automatically; reload the window if the server does not appear.
{% endstep %}

{% step %}

### Test in Assistant panel

Open the Zed Assistant panel and type: *List my* <code class="expression">space.vars.ionos\_cloud</code> *data centers.*

{% hint style="success" %}
**Result:** Zed calls `list_datacenters` and returns your data centers.
{% endhint %}
{% endstep %}
{% endstepper %}

{% hint style="info" %}
**Note:** All tools are registered at startup by default, so Compute Engine and Object Storage tools appear immediately. To reduce the startup tool count (for example, on clients with a tool-count cap), set `IONOS_MCP_LOAD_MODE=lazy` in the `env` block and call the `ionos_load_compute_tools` or `ionos_load_objectstorage_tools` sentinels on demand. For more information, see [<mark style="color:blue;">Selective Tool Loading</mark>](/cloud/ai/mcp-server/configuration/selective-tool-loading.md).
