Key Features

Agent-Only Access

Card details are delivered exclusively to the agent through MCP (Model Context Protocol) tools. Sensitive card information is not displayed in plaintext on web interfaces.

Controlled Budget

Each card has a predefined lifecycle spending limit of $20. Transactions outside supported online payment scenarios (e.g., POS or ATM usage) are automatically rejected.

Instant Activation

Agent Card can be integrated quickly through the MCP protocol. Once connected, the agent can automatically discover and invoke available payment tools.

On-Chain Funding

Agent Card supports funding via stablecoins, including USDC and USDT. Remaining balances can be converted back into stablecoins and returned to the user's crypto wallet at any time.
