AI agents call GetV1InstancesApiKeysById to retrieve information from BlindPay MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is fundamentally a Read operation as it retrieves existing data without modification. However, the severity is elevated to 'high' rather than 'low' because API keys are cryptographic secrets whose disclosure would grant an attacker full access to BlindPay's stablecoin payment infrastructure, potentially enabling unauthorized transactions, account compromise, and financial fraud.
From the tool's definition Tool name contains 'Get' and description states 'Retrieve Api Key', indicating a data retrieval operation. However, API keys are security-sensitive credentials that, if leaked, could enable unauthorized access to the payment infrastructure.
Documented attack patterns abuse exactly the kind of access GetV1InstancesApiKeysById 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 GetV1InstancesApiKeysById:
{
"version": "1",
"default": "deny",
"tools": {
"GetV1InstancesApiKeysById": {}
}
}GetV1InstancesApiKeysById is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Retrieve Api Key. It is categorised as a Read tool in the BlindPay MCP Server MCP Server, which means it retrieves data without modifying state.
Register the BlindPay MCP Server MCP server in PolicyLayer and add a rule for GetV1InstancesApiKeysById: 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 BlindPay MCP Server. Nothing to install.
GetV1InstancesApiKeysById is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the GetV1InstancesApiKeysById 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 GetV1InstancesApiKeysById. 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.
GetV1InstancesApiKeysById 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.
Free to start. No card required.
