POLICY

How to control AI42-MCP X402 Payment Server

PolicyLayer is an MCP gateway — it sits between your AI agents and AI42-MCP X402 Payment Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default

{
  "fetch-with-payment": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Cap read operations

{
  "get-balance": {
    "limits": [
      {
        "counter": "get-balance_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
