Tokenize a card into the Braspag vault / Cartão Protegido (POST /card). Returns a reusable token that can substitute CardNumber on future sales — reduces PCI scope and enables cross-acquirer reuse.
AI agents use tokenize_card to commit financial operations through Mcp Ap2 — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool stores payment card data into a financial vault and generates a reusable payment token. While it doesn't directly move money, it handles sensitive financial instrument data (card numbers) and creates tokens that can be used to authorize future financial transactions.

Documented attack patterns abuse exactly the kind of access tokenize_card gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for tokenize_card:
{
"version": "1",
"default": "deny",
"tools": {
"tokenize_card": {
"deny_if": [
{
"conditions": [],
"on_deny": "Requires human approval."
}
]
}
}
}Any call to tokenize_card is blocked until a human approves it. The rest of the server keeps working.
Free to start. No card required.
Tokenize a card into the Braspag vault / Cartão Protegido (POST /card). Returns a reusable token that can substitute CardNumber on future sales — reduces PCI scope and enables cross-acquirer reuse. It is categorised as a Financial tool in the Mcp Ap2 MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the Mcp Ap2 MCP server in PolicyLayer and add a rule for tokenize_card: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Ap2. Nothing to install.
tokenize_card is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the tokenize_card rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for tokenize_card. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
tokenize_card is provided by the Mcp Ap2 MCP server (@codespar/mcp-ap2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Ap2, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
