How Scoped API Keys Keep a Claude and Quin Connection Secure

A law firm's operations lead wants to let associates ask Claude about client meetings and case notes, but firm policy requires knowing exactly what has access to what, and being able to cut off any single connection without touching the rest. Before anyone connects anything, that question has to be answered first.

What Tends to Get Missed

• One connection should not be an all or nothing bet. If every AI assistant a firm uses shares the same credential, disabling access for one means disabling it for all of them.
• Compliance teams need a clear answer about where data goes. Client information moving into an AI assistant has to be explainable, including encryption and who can revoke access.
• Access sprawls faster than anyone expects. A firm that starts with one AI assistant connected often adds a second and third within a year.
• Revocation has to be fast and isolated. When someone leaves or a key is exposed, the fix should take seconds, not a fresh authentication of every other connection.
• Encryption standards should not vary by integration. A connection through Claude should meet the same bar as every other way data moves through Quin.

How Quin Handles It

Every AI assistant that connects to Quin through MCP does so with its own API key, generated specifically for that connection. Claude gets a key, a different internal tool gets its own, and neither depends on the other to keep working.

Picture an operations lead at a mid size advisory firm who rolled out Claude to the sales team last quarter and is now piloting a separate internal tool for research. Both need access to Quin's calendar and contact data, so both get their own key at setup. When the pilot tool is replaced two months later, revoking its key takes one step and the sales team's Claude connection is untouched.

That same connection runs on encryption in transit and at rest, and Quin is SOC 2 Type II certified, the same standard applied across every integration, not a special case for MCP. For a firm handling client financial or legal information, that standard does not change depending on which assistant is asking, and isolating one connection from another is often what makes a firm comfortable connecting an AI assistant to sensitive data at all.

Best Practices

• Name each API key by its purpose. A key labeled for Claude versus one labeled for a pilot tool makes account review much faster later.
• Set a recurring check on active connections. A quarterly look at what is connected and why keeps the list from growing past what anyone remembers approving.
• Revoke before you retire, not after. Cut access the same day a tool is decommissioned rather than leaving an unused key active.
• Loop in whoever owns compliance before the first connection. A security review done up front avoids explaining a connection after the fact.

Setting It Up

Generating an API key for Claude takes a few minutes and does not require any changes to how Quin already handles calendar, CRM, or contact data elsewhere in the account. Each key can be renamed, reviewed, or revoked on its own, independent of any other connection. That screen lives in the Quin account, under Settings, then Integrations.
