Server URL

Sign-in uses OAuth. When you connect, the app opens a Vollna page in your browser. Sign in, check the app’s name and the team it will act in, and click Allow. You never paste a password or an API key into the app. Each team member connects their own apps. Settings → Developers → MCP shows your teams, what is left of today’s limits and your connected apps.

​
Connect your app

Works on every Claude plan. The Free plan allows one custom connector.
  1. Open Customize → Connectors.
  2. Click + Add, then Add custom connector.
  3. Enter a name, for example Vollna, and paste the server URL.
  4. Sign in to Vollna and click Allow.
  5. In a chat, click +, then Connectors, and turn Vollna on.
On a Claude Team or Enterprise plan, an owner adds the connector under Organization settings → Connectors first. Members then click Connect.Claude’s menus change from time to time. Anthropic’s guide has the current steps.

​
Check it works

Ask the app: “What Vollna plan am I on?” It answers with your plan and team. When it says it has no Vollna tools, turn the connector on for the chat, or connect again.

​
Teams

One connection works in every team you are an active member of, when that team’s plan includes MCP. The app starts in the team you have open in Vollna. To work in another team, ask the app to switch: “Switch to my Acme team.” The team open in your browser stays as it is.

​
Troubleshooting

​
Disconnect

  1. Open Settings → Developers → MCP.
  2. Under Connected apps, click Revoke next to the app.
The app has to ask for access again before it can connect.
