Agent cards

Agent cards overview

Single-use card credentials that give an agent real payment authority.

Agent Cards give an AI agent real payment authority on Ramp — a single-use card credential, scoped to one merchant and capped at the requested amount. They work with any agent connected to Ramp, through either MCP or the Ramp CLI.

How it works

Three pieces make a purchase possible:

  1. A single-use credential. Ramp mints a fresh PAN and CVV at purchase time, scoped to one merchant and capped at the requested amount. It expires after the first authorization or 12 hours, whichever comes first.
  2. A Ramp fund (Spend Controls) sets the policy ceiling. The agent can only generate credentials against funds you're scoped to.
  3. A connected agent — through an MCP runtime such as Cursor, Claude, ChatGPT, or Perplexity, or through the CLI's agentic-purchase skill for terminal-based agents.

Both honor your existing Ramp permissions, and the resulting charge appears as a regular transaction on the linked fund. Any write performed through Ramp is attributed and audited according to the authenticated user and agent workflow.

Prerequisites

  • A Ramp account with at least one active fund.
  • An agent connected via an MCP runtime or the Ramp CLI.
  • Enrollment in Agent Cards.
  • The cards:read_agentic scope (and spend_limits:write for writes).
