Stop Pasting Secrets into AI Chat - Use AI-Safe Credentials Instead

The Awkward Moment Every Developer Knows

You're pair programming with Claude Code, and it asks:

"I need your database credentials to run this migration."

And then you do the thing. You paste your password right into the chat. 🤦

We've all been there. But here's the problem:

That secret is now in your conversation history
It might end up in logs or training data
You can't easily rotate it
There's no audit trail

What If AI Could Use Secrets Without Seeing Them?

This is exactly what I built secretctl to solve.

Instead of exposing credentials, secretctl injects them as environment variables. The AI assistant can use your secrets to run commands, but never actually sees the plaintext values.

How It Works with Claude Code

Add secretctl as an MCP server in your Claude Code config:

{
  "mcpServers": {
    "secretctl": {
      "command": "secretctl",
      "args": ["mcp-server"],
      "env": {
        "SECRETCTL_PASSWORD": "your-master-password"
      }
    }
  }
}

Now Claude Code can:

✅ List your available secrets
✅ Run commands with injected credentials
✅ See masked values (e.g., ****WXYZ)
❌ Never see actual plaintext values

Example: Database Migration

You: "Run the database migration using my prod-db credentials"

Claude: I'll run the migration with your credentials injected.
        [Executes: secretctl run prod-db -- npm run migrate]

        Migration completed successfully!

The AI executed the command with real credentials, but never saw password123 in the chat.

Why This Matters

Traditional Approach	secretctl Approach
Paste secrets in chat	Secrets injected via env vars
Visible in history	Never exposed to AI
No audit trail	Full audit logging
Hard to rotate	Single source of truth
Risk of leakage	Zero plaintext exposure

Multi-Field Secrets

Real credentials are complex. secretctl supports multi-field secrets with templates:

# Database credentials
secretctl set prod-db --template database
# Stores: host, port, database, username, password

# SSH configurations
secretctl set bastion --template ssh
# Stores: host, port, username, private_key

# API credentials
secretctl set stripe --template api
# Stores: api_key, api_secret, endpoint

Desktop App for Visual Management

Prefer a GUI? secretctl includes a full-featured desktop app:
