Zed

Zed 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 zed.dev
• The ionoscloud-mcp binary built and available. For more information, see Quick Start
• An IONOS CLOUD API token. For least-privilege access, see Authentication 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:

{
  "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:

{
  "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"
        }
      }
    }
  }
}

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.

Verify the connection

1

Reload Zed

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

2

Test in Assistant panel

Open the Zed Assistant panel and type: List my IONOS CLOUD data centers.

Result: Zed calls list_datacenters and returns your data centers.

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 Selective Tool Loading.
