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

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

## Why update-label is rated Medium

The update-label tool modifies label properties in Gmail but does not delete data or cause irreversible changes. Changes to label names and visibility settings are reversible (labels can be renamed again or visibility toggled back). This falls squarely into the Write category.

From the tool's own definition: "Tool description states 'Modify label properties' and explicitly mentions 'renaming labels, changing visibility' – these are reversible modifications to metadata."

## Use case

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

## Recommended policy (PolicyLayer)
