Environment Variables tools provide persistent, encrypted key-value storage for your AI agent. Store API keys, database URLs, configuration settings, and any secret your AI tools need โ all encrypted with your private key.
When other tools need credentials (like a database connection URL or SMTP password), they automatically read from your stored environment variables. Set them once, and every tool that needs them will work seamlessly.
Why use Environment Variables?
What can you do?
Database credentials
Store MySQL, PostgreSQL, Redis, or MongoDB connection URLs securely for the database tools.
SMTP configuration
Save email server credentials so the email tools can send messages on your behalf.
API keys
Store third-party API keys (GitHub tokens, service credentials) for your AI agent to use.
Project settings
Save project-specific configuration that your AI can reference across sessions.
How to set up
Set a variable
Ask your AI: "Set my MYSQL_URL to mysql://user:pass@host:3306/db"
Use it
Other tools (like database_mysql_query) will automatically read the stored URL.
List variables
Ask your AI to list all stored environment variable keys.
