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

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

  "method": "tools/call",
  "params": {
    "name": "create_label",
    "arguments": {}
  }
}
```

## Why create_label is rated Medium

This tool creates a new label resource on a Trello board. Label creation is reversible (labels can be deleted) and does not irreversibly destroy data, execute arbitrary code, or move money. It modifies board state by adding metadata.

From the tool's own definition: "Tool name is 'create_label' and description states 'Create a new label on a board'. The verb 'create' indicates data creation, which is a write operation."

## Use case

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

## Recommended policy (PolicyLayer)

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

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