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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "rate-limited",
    "arguments": {}
  }
}
```

## Why rate-limited is rated Low

An echo tool retrieves and returns data provided to it with no side effects. This is a read operation. The rate limiting indicates low risk of abuse. Severity is low because even if misused, echoing data back causes no harm to systems or data integrity.

From the tool's own definition: "The tool is described as 'A rate-limited echo tool' — echo tools simply return input data without modification, deletion, or side effects. Rate limiting is a safety wrapper, not a functional descriptor."

## Use case

AI agents call rate-limited to retrieve information from Frontmcp 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 Frontmcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "rate-limited": {}
  }
}
```
