Accessing settings

Server controls are available directly on the Overview tab of the server detail page. There is also an Edit button in the top-right corner that opens the full settings form.

​
Activate / Deactivate a server

Every server has an Active toggle switch visible at the top of the Overview tab.
  • Active (on): The server accepts incoming MCP requests normally.
  • Inactive (off): The server rejects all incoming requests with a 503 Service Unavailable response. Your tools, secrets, and configuration are preserved.
Use this to temporarily disable a server without deleting it — for maintenance, billing concerns, or while debugging a production issue. Toggle it back on when you’re ready.
Deactivating a server takes effect immediately. Connected AI clients will lose access until the server is re-activated.

​
Restart a server

The Restart button (visible in the server header) stops all active connections, clears the runtime state, and brings the server back online with a fresh execution environment. When to restart:
  • After updating secrets — to ensure the new values are loaded immediately
  • If the server appears unresponsive without a clear error in the logs
  • After making significant changes to multiple tools at once
Restarting terminates all in-flight tool executions. Any requests currently being processed will receive an error response. Restart during a low-traffic period when possible.

​
Edit server details

Click the Edit button to open the full server form where you can update:
  • Title and Description
  • Category
  • Instructions (AI system prompt)
  • Rate limit per minute
  • Security mode
The Code and Subdomain fields cannot be changed after creation — they are permanent identifiers.

​
Change the security mode

You can switch security modes at any time from the edit form. The subdomain URL stays the same.
Changing the security mode takes effect immediately. Connected AI clients that no longer provide valid credentials will receive 401 Unauthorized.
See Security Overview for a full description of each mode.

​
Delete a server

Deleting a server is permanent and removes:
  • The server and its subdomain endpoint
  • All tools on the server
  • All secrets stored on the server
  • All traffic and error logs associated with the server
This action cannot be undone. Connected AI clients will immediately lose access to the server’s tools. The subdomain is released and may become available to others.
To confirm, you’ll be asked to type the server name before the delete button becomes active.

​
Blocking access without deleting

If you need to temporarily block all access:
  1. Deactivate the server (toggle switch) — simplest option, fully reversible
  2. Switch to API Key mode and keep the key secret — clients without the key get 401
  3. Set rate limit to 0 and deactivate — belt and suspenders for critical servers
