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

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

## Why update_tag is rated Medium

This tool modifies existing tag names in n8n's workflow management system. It is a Write operation because it creates or modifies data reversibly — tag name changes can be undone by updating again. Severity is medium: misuse could cause workflow confusion and require administrative cleanup, but affects only organizational metadata, not workflow executions or destructive operations.

From the tool's own definition: "Tool description states 'Perbarui nama tag' (Update tag name) — a modification operation on existing data. The tool updates tag metadata in n8n, which is reversible (the old tag name can be changed back)."

## Use case

AI agents use update_tag to create or update resources in n8n MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your n8n MCP Server environment.
