Create Virtual Account
AI agents use PostV1InstancesReceiversVirtualAccounts to create or update resources in BlindPay MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BlindPay MCP Server environment.
This tool creates virtual accounts used for payment operations in a stablecoin payment system. While it is reversible (virtual accounts can be deleted, as evidenced by sibling DeleteV1InstancesReceiversVirtualAccounts operations), it commits financial infrastructure setup that could enable unauthorized payments or fraud if misused by an AI agent.
From the tool's definition Tool name 'PostV1InstancesReceiversVirtualAccounts' with description 'Create Virtual Account' indicates a POST operation that creates new financial infrastructure objects.
Documented attack patterns abuse exactly the kind of access PostV1InstancesReceiversVirtualAccounts gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BlindPay MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for PostV1InstancesReceiversVirtualAccounts:
{
"version": "1",
"default": "deny",
"tools": {
"PostV1InstancesReceiversVirtualAccounts": {
"limits": [
{
"counter": "postv1instancesreceiversvirtualaccounts_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}PostV1InstancesReceiversVirtualAccounts stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PostV1InstancesReceiversVirtualAccounts is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the PostV1InstancesReceiversVirtualAccounts 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 PostV1InstancesReceiversVirtualAccounts. 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.
PostV1InstancesReceiversVirtualAccounts is provided by the BlindPay MCP Server MCP server (blindpaylabs/blindpay-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from BlindPay MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
