Manage & revoke AI access

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

Claude

• Go to Settings → Connectors(claude.ai/settings/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 (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, find the connected client, and revoke it there. This cuts off access immediately even if you can’t reach the client — the universal kill switch.

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.
