Manage API keys and budget caps

The agent securely vaults provider keys and configures spending limits to prevent unauthorized or excessive usage.

How it works

Changes data in your accountsOperations and infrastructure

The agent uses get_vault_link to generate a secure link for the user to input their own provider keys (BYOK). It then uses policy management capabilities (via direct API calls if MCP tools allow, or by guiding the user) to set daily or monthly caps. This ensures the agent operates within defined financial boundaries and security protocols.
