Reconnecting an app replaces its key

Every time you connected an app — Claude Desktop, an MCP client, any integration — the portal issued a new access token and left the previous one working. Reinstall the app, switch device, or disconnect and reconnect, and each round left another live key behind, valid for a year. Your token list grew, and every entry in it still opened the door.

Reconnecting now replaces that app's key rather than adding one: after a fresh connection, the app has exactly one credential and the earlier ones are gone. The new token is always issued first, so a reconnection can never leave an app without access.
