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

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

## Why update_cycle is rated Medium

The tool performs an update operation on cycle entities within a project management system. Updates are reversible modifications (Write category) rather than irreversible deletions (Destructive). The severity is medium because misuse could disrupt project timelines and team coordination, but changes can typically be reverted.

From the tool's own definition: "Tool name 'update_cycle' combined with server description stating 'full CRUD operations' and presence of sibling tools like 'create_cycle' and 'delete_cycle' indicates this modifies cycle data reversibly."

## Use case

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

## Recommended policy (PolicyLayer)

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

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