n8n-nodes-ai-cost-guard

AI Cost Guard is a small n8n community node for estimating LLM token costs, checking run/month budgets, and stopping risky AI workflows before they scale.

Problem

AI workflows can become expensive when prompts grow, tools retry, or a workflow runs many times per month. n8n users need a simple budget guard inside the workflow, not only a dashboard after the bill arrives.

Solution

The node reads workflow or execution JSON, detects model and token usage when available, estimates missing token usage from text length, and returns:

• input, output, and total token estimate;
• cost per run;
• projected monthly cost;
• run budget and monthly budget status;
• guardrail recommendations;
• optional hard failure when a run exceeds budget.

Access

Free Preview returns the core budget decision and limited recommendations.
