Sigmund

About two minutes

Add Sigmund to your assistant.

Connect it once in Claude or ChatGPT. Then ask your assistant to collect documents, and Sigmund sends the links, checks every upload and tells you when the pack is ready.

You'll be asked to sign in to Sigmund when you connect. No account yet? You can create one, free, on the same screen.

In Claude

  1. In Claude, open Customize › Connectors.
  2. Select + Add, then Add custom connector.
  3. Name it Sigmund, paste the connection URL and select Continue.
  4. Keep the sign-in settings Claude detects and select Continue. Under Authentication, choose Sign in now, then select Add.
  5. Sign in to Sigmund, or create your free account.
  6. In any chat, select + › Connectors and turn Sigmund on.

On Team and Enterprise plans, an owner adds Sigmund once in Organization settings › Connectors (Add › Custom › Web). Everyone else finds it under Customize › Connectors and selects Connect. Free Claude plans can add one custom connector.

In ChatGPT

  1. In ChatGPT on the web, open Plugins.
  2. Select +, then Add custom MCP server.
  3. Name it Sigmund and paste the connection URL under Connection.
  4. Choose OAuth for authentication, accept the warning and select Create as a plugin.
  5. Install the plugin, then sign in to Sigmund or create your free account.
  6. In a new chat, type @ and pick Sigmund.

On Business and Enterprise workspaces, an admin or owner adds Sigmund for everyone. If you don't see Add custom MCP server, your plan or workspace may not allow custom servers yet.

Then just ask.

Tell your assistant what you need and from whom. Sigmund creates the application, sends each person their private link, and checks everything as it arrives.
