  "jsonrpc": "2.0",

## 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 own definition: "'Search for paid API services' — this is a discovery/search operation with no side effects"

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Pay Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "pay_discover": {}
  }
}
```
