Manage & revoke AI access

You’re always in control of your AI’s connection to Pennyweight. The grant renews every time you use it and expires after 30 days of inactivity; you can cut it off any time. Here’s how, per client.

Claude

  • Go to Customize → Connectors(claude.ai/customize/connectors).
  • Find Pennyweight, open the three-dot menu, and choose Remove (or disconnect).
  • To reconnect later, add the custom connector again — see connect to Claude.

ChatGPT

  • Open Settings → Connectors(or Apps & Connectors).
  • Select Pennyweight and remove it.
  • Reconnect via connect to ChatGPT.

Gemini

  • Gemini app: on a computer, open gemini.google.com → Settings → Connected Apps, find Pennyweight under Custom apps, and remove it.
  • Gemini CLI: remove the pennyweight entry from your ~/.gemini/settings.json, and delete the stored token file if you want a clean slate.
  • See connect to Gemini for details.

Grok

  • Open grok.com/connectors(or Connectors in Grok’s settings), find Pennyweight, and remove it.
  • Reconnect via connect to Grok.

Any other MCP client

  • Remove the Pennyweight connector wherever your client lists its MCP servers / connectors (settings UI or config file). See connect any MCP client.

Revoke from Pennyweight itself (works for any client)

Whatever client you used, you can also revoke from Pennyweight’s own side: open Settings → Connect your AIin the web app. Every AI client you’ve connected is listed separately, with when it was connected and when the grant expires, and each one can be revoked on its own. This cuts off access immediately even if you can’t reach the client — the universal kill switch.

Revoking takes effect on the client’s very next attempt to touch your data. You don’t need to wait for anything to expire, and you don’t need the client’s cooperation.

If a connection misbehaves

The reliable fix for an AI connector that won’t authenticate or has gone stale is to remove it and add it again. Reconnecting starts a fresh sign-in (two-factor + passphrase) and a new 30-day grant.

What revoking does

Once revoked, that AI client can no longer read or change your ledger. Your data is untouched — it stays encrypted with your passphrase either way. Revoking only removes the assistant’s access token; it never affects your account, your transactions, or your other connections.

Turning off two-factor revokes everything

Connecting an AI to Pennyweight requires two-factor authentication, and it stays required. If you ever turn two-factor off on your account, every AI connection is revoked automatically. Turn it back on and reconnect the clients you still want.
