How do I get a PayClaw API key to use this MCP server?

Visit payclaw.io/dashboard/settings and generate an API key from your account dashboard. Set it as the PAYCLAW_API_KEY environment variable when running the MCP server.

Can I customize the API endpoint this server connects to?

Yes. The PAYCLAW_API_URL environment variable lets you override the default endpoint (https://payclaw.io). This is useful for testing or private deployments.

What does 'human-approved' mean for card issuance?

Card creation requests go through an approval workflow before issuance. This ensures humans retain control over spending by AI agents rather than allowing fully autonomous card creation.

Are these real Visa cards or virtual-only?

These are virtual Visa cards designed for online and digital payments. They are issued just-in-time (JIT) for specific transactions or time-limited use cases.

What happens if an AI agent tries to spend beyond the card limit?

Virtual cards are issued with configurable spending limits. Transactions exceeding the limit will be declined by the Visa network, preventing unauthorized overspending.
