How to Use the Fly.io Extended MCP in Windsurf

Q: Is Fly.io Extended safe to use with Windsurf for destructive actions?

The server exposes deleteapp and deletemachine tools, so you need to set your own guardrails. We recommend keeping these tools restricted unless you have an automated approval flow in your agent logic.

Use the Fly.io Extended MCP Server in Windsurf to let Cascade manage your infrastructure directly from your codebase.

Automate infrastructure lifecycles in Windsurf

Cascade doesn't just read your config. It takes command of your environment to handle machine states and volume scaling without you leaving the editor. Use `create_machine` and `update_machine` to define your infrastructure, then let the agent handle the heavy lifting of `start_machine` or `stop_machine` during deployments.

Zero-touch resource scaling

Forget about manual volume management. The agent monitors your storage needs and triggers `extend_volume` or `create_volume` the second your app hits a capacity limit. This MCP Server provides the hooks for Cascade to inspect your current footprint using `list_volumes` and `get_app` before it makes any changes to your production setup.

Manage SSL without leaving the IDE

Stop jumping to a browser to fix expired certificates. Cascade handles your entire security handshake using `create_acme_certificate` and `check_certificate` within the Windsurf interface. It verifies your domain state via `list_certificates` and ensures your production traffic stays encrypted by automating the renewal process in the background.

Setup guide

Set up Fly.io Extended MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Fly.io Extended MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Fly.io Extended payment history." If connected, Cascade will call the Fly.io Extended tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Fly.io Extended MCP in Windsurf

Open your MCP settings in Windsurf and add the server to your configuration file. Once you refresh your MCP panel, Cascade will automatically detect all 28 tools and start managing your cloud resources.

Yes, but you should treat those operations with care. The agent can use `extend_volume` or `list_volume_snapshots` to maintain your storage, but verify the machine state first using `get_volume`.

The server exposes `delete_app` and `delete_machine` tools, so you need to set your own guardrails. We recommend keeping these tools restricted unless you have an automated approval flow in your agent logic.

Every one of the 28 tools is available for Cascade to call. Whether you need to `request_oidc_token` for auth or `wait_machine` for a deployment, the agent has full access.

This server only interacts with your specific Fly.io organization via an ephemeral token. It does not store your private code or data; it only passes your infrastructure metadata through encrypted API calls to the platform.
