## Facts

- Tool: `getCounter`
- Server: API Ninjas (`https://mcp.api-ninjas.com/mcp`) — https://policylayer.com/tools/com-api-ninjas-mcp.md
- Homepage: https://github.com/https://mcp.api-ninjas.com/mcp
- Risk category: Read (Low risk)
- Registry record: grade D, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 3 (1 required)
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | yes | ID to specify the counter. Use a new id to create a new counter. |
| `hit` | boolean | no | Whether to increase the count by 1. If used, must be set to true. |
| `value` | integer | no | Set the count to a specific integer value. Setting the value to 0 resets the counter. |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "getCounter",
    "arguments": {
      "id": "<id>"
    }
  }
}
```

## Why getCounter is rated Low

Even though getCounter only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call getCounter to retrieve information from API Ninjas 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 API Ninjas:

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