## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why finance-creditCardNumber is rated Low

This tool generates fake, randomly constructed credit card numbers for testing or development purposes. It does not access real financial systems, retrieve real card data, or perform any transactions. The server description explicitly states it generates fake data. Severity is low because while fake credit card numbers could theoretically be misused, the tool itself has no side effects and produces synthetic data.

From the tool's own definition: "Generates a random credit card number — this is fake/synthetic data generation using Faker.js, with no real financial data accessed or transactions made."

## Use case

AI agents call finance-creditCardNumber to retrieve information from Faker MCP Server 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 Faker MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "finance-creditCardNumber": {}
  }
}
```
