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

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

## Why timers_increment is rated Medium

This tool modifies the state of a timer by incrementing its value. This is a reversible write operation (the timer can be decremented or reset), affecting only presentation timing within ProPresenter 7. The blast radius is low as it only impacts live presentation timer state.

From the tool's own definition: "Increment a specific timer by a duration"

## Use case

AI agents use timers_increment to create or update resources in Propresenter, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Propresenter environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Propresenter:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "timers_increment": {
      "limits": [
        {
          "counter": "timers_increment_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
