Credential Security for AI Agents

Let your agents work.
We make sure they behave.

Davy.Locker acts like the bank between your agents and your sensitive information. They get all of the data they need to complete their tasks while we keep it fully encrypted for you, meaning they never see any of the information. No secrets are ever exposed. It's just agents doing their jobs and us keeping your data safe.

🔒

Zero-knowledge encryption.

Your credentials are encrypted with AES-256. Not even Davy.Locker can read them.

🛡

Agents never see secrets.

The proxy injects credentials on their behalf. They get the job done without the keys.

📜

Full audit trail.

Every access logged. Know exactly which agent used which credential, when, and why.

🔓

Revoke access instantly.

Scope by time, method, or domain. Session ends, access ends. No lingering keys.

The Problem

You're handing over the keys to the kingdom

Every time you give Claude Code, Cursor, or any AI agent your API keys, passwords, or tokens—you're giving it full, unrestricted access to your accounts. And right now, there's nothing standing between that agent and everything it can do with them.

🔑

Your agent sees everything

When you give an agent your API key, it has that key in memory. It can read it, store it, and accidentally expose it. One bad prompt and your credentials could end up in a log file, a chat window, or worse.

Agents can be tricked into revealing your credentials
👁

You have no idea what it did

Which accounts did your agent access? What actions did it take? If something goes wrong—charges on your Stripe, files deleted, data leaked—you have zero record of what happened or when.

No audit trail means you can't even investigate
🔄

There's no off switch

Once your agent has the key, you can't take it back mid-session. There's no way to say "you can deploy but you can't read the database." It's all or nothing. Full access or no access.

No scoping, no limits, no revocation

Right now, your credentials are stored in plain text.

MCP servers—the way AI agents connect to your tools—store your API keys and passwords in plain text config files on your computer. Any agent, any app, anything that can read that file has full access to all of them.

What does that mean for you? It means your Stripe keys, your deployment tokens, your database passwords—they're all sitting in a file that's as secure as a sticky note on your monitor.

Where You Stand

The Security Spectrum

Most people using AI agents are at Level 0 or 1 right now. That's not a criticism—the tools to do better simply haven't existed. Until now.

Where most people are today

Level 0

No Protection

API keys pasted directly into agent chat, hardcoded in files, shared in messages

Extremely common
Level 1

Basic Storage

Credentials in config files on your computer. Not encrypted. Any app or agent can read them.

Where most agent users are
Level 2

Password Manager

Stored securely, but when your agent needs access, you still hand over the raw key. The agent holds it in memory.

Better, but not enough

Where you should be

Level 3
FREE

How It Works

Bank-level security.
Your agents walk in. Your secrets never leave.

Davy.Locker sits between your AI agents and your sensitive information. Your agents get what they need to do their job. They never see or hold the actual credentials.

1

Your agent needs access

"I need to deploy to Vercel" or "I need to query the database" — your agent tells Davy.Locker what it needs.

2

We check permissions

Is this agent allowed? What level of access? You set the rules — Davy.Locker enforces them.

3

We handle the credentials

Davy.Locker pulls the credential from the encrypted vault and delivers it directly to the service — like an armored truck. Your agent never sees or touches the raw key.

4

We filter what comes back

Before the response reaches your agent, we strip out sensitive data. Bank account numbers, tax IDs, personal information — your agent gets what it needs, nothing it shouldn't see.

Everything is recorded

Every action your agent took is logged. What it accessed, when, and what it did. If anything ever goes wrong, you have the full tape.

Your secrets stay locked

Agents never see your keys

Your API keys, passwords, and tokens live in an encrypted vault. When your agent needs one, Davy.Locker delivers it directly to the service—the agent never holds the raw credential in memory.

You choose what each agent can access
Access auto-expires when the session ends
Revoke access instantly, anytime
Sensitive data stays hidden

Agents only see what they need

When your agent queries an API, the response often contains sensitive data it doesn't need. Davy.Locker filters that out automatically—your agent gets the useful data, never the bank details or personal info.

Built-in filters for 15+ popular services
Auto-detects credit cards, SSNs, private keys
Customizable per service and per agent
Every action on camera

You see everything they do

Every time an agent accesses a credential, makes an API call, or gets a response—it's logged. You always know exactly what your agents did, when they did it, and whether anything looks off.

Meet The Kraken

The security guard
that never sleeps

Every bank has cameras. Yours has The Kraken—an AI security guard that watches every transaction, learns what normal looks like, and responds to threats in seconds. When something's wrong, it doesn't just sound the alarm. It slams the windows shut, re-keys the vault, and quarantines the suspect—before you've finished your coffee.

Watches the Floor
Learns normal patterns, spots anomalies. 847 requests in 12 minutes when the baseline is 30/hour? Something's wrong. Flagged instantly.
Re-Keys the Vault
Compromised credential? Auto-rotated via provider API. The vault combination changes. Every clean agent gets the new key. The suspect gets locked out.
Checks Expired Badges
"Agent research-bot hasn't entered the bank in 90 days. Revoke their access?" Keeps the authorized list tight.
