WHAT IT DOES

What pay_discover does on Pay Mcp

AI agents call pay_discover to retrieve information from Pay Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why pay_discover is rated Low

pay_discover searches for paid API services that accept USDC payments. Despite being on a financial server, the tool itself only retrieves/queries information about available services. It does not initiate payments, move funds, or modify any state. The financial context of sibling tools does not elevate this read-only search operation.

From the tool's definition 'Search for paid API services' — this is a discovery/search operation with no side effects

RECOMMENDED RULE

The rule that runs pay_discover safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pay Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pay_discover, this is the rule to start with:

pay_discover Allowed

pay_discover is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "pay_discover": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Pay Mcp, apply this rule, and every pay_discover call is checked against it from then on.
