Kar69 96 Agentpay MCP server — FAQ

Common questions about connecting and running Kar69 96 Agentpay.

  • What does AgentPay do?

    AgentPay enables AI agents to execute payments with built-in human approval gates and encrypted credential storage. It provides local-first security, budget controls, and browser navigation during checkout via Anthropic integration.

  • How do I set up AgentPay locally?

    Install via `npx @useagentpay/mcp-server@0.1.8`, then set AGENTPAY_PASSPHRASE (for credential decryption) and ANTHROPIC_API_KEY (for checkout navigation). The server runs over stdio transport.

  • How are payment credentials secured?

    Credentials are encrypted locally and decrypted only during purchase execution using your AGENTPAY_PASSPHRASE. This local-first approach keeps sensitive data off remote servers.

  • Can I set spending limits on agents?

    Yes. AgentPay includes budget controls that let you enforce per-transaction and cumulative spending caps on autonomous agents before payments execute.

  • Do I need human approval for every payment?

    AgentPay is designed with human approval gates, allowing you to require confirmation for transactions above thresholds or for all payments, depending on your security policy.
