{% hint style="info" %}
You might want to approve all MCP tool calls without approval in Cursor/VScode setting, or add the DataFlint MCP requests to the allowlist of MCP tools that does not require approval.
{% endhint %}

**Highlight** will **add code highlight to your current job** based on the last run. You can also trigger it by asking Cursor "add highlight for this job"
