Track LLM Cost vs Quality Using MCP Servers.
Your OpenAI bill grew from $200 to $2,400 in 2 months and you have no idea which feature caused it , because you track API spend at the account level, not at the prompt level
Works with every AI agent you already use
…and any MCP-compatible client
Waiting for input…
Gemini How It Works
Your AI agent pulls the last 7 days of LLM traces from Langfuse: every prompt chain, every intermediate step, every quality score, every error.
It crosses this data with Helicone's cost analytics: cost per request, cost per user, cost per feature, token consumption by model.
The result goes to Google Sheets as a multi-tab dashboard. Tab 1 , Cost Attribution: 'Feature X costs $847/month (42% of total).
It uses GPT-4 for a classification task that GPT-3.5-turbo handles at 94% accuracy for $31/month.' Tab 2 , Quality Trends: 'The summarization prompt scored 4.2/5 average last week, down from 4.6 two weeks ago.
The June 1 prompt update degraded quality. Roll back to v3.' Tab 3 , Latency Analysis: 'P95 latency for the chat chain is 8.2 seconds.
Step 3 (RAG retrieval) takes 5.1 seconds , it is the bottleneck, not the LLM call.' Tab 4 , Anomalies: 'User X triggered 340 requests in 1 hour , abuse or legitimate use? Cost impact: $127.' The dashboard turns invisible LLM operations into decisions: which model to downgrade, which prompt to roll back, which feature to optimize.
MCP Server Orchestration: 3 MCP Servers, one intelligent agent
Connect Langfuse, Helicone and Google Sheets MCP servers so your AI agent pulls LLM trace data from Langfuse , latency, token usage, error rates and quality scores per prompt chain , crosses it with cost and usage analytics from Helicone, and builds a unified observability dashboard in Google Sheets that shows exactly which prompts cost the most, which chains are slowest, and where quality is degrading before your users complain. AI engineers, indie hackers and startup teams running LLM-powered products who notice their API costs climbing but cannot attribute spend to specific features, cannot identify which prompt changes improved or degraded quality, and are flying blind on production LLM performance because 'it works in the playground' is their entire monitoring strategy.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 4,700+ MCP servers and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across every tool, in one conversation. That's what this infrastructure was built for.
Cross-Platform Intelligence
Your agent doesn't just connect to tools. It understands the relationships between them. Data flows where it needs to go, automatically, with full context preserved across every platform.
Contextual Reasoning
Every decision your agent makes considers the full picture. It reads CRM data, checks calendars, reviews conversation history, and acts on everything at once. Not step by step. All at once.
Productivity at Scale
What used to take 45 minutes across five different dashboards now takes one sentence. Your agent runs the entire workflow end to end while you focus on decisions that actually matter.
Zero-Config Reliability
No API keys to paste. No webhooks to configure. No YAML to debug. Connect your MCP servers once, and your agent handles the rest. Every time, without intervention.
Made for
exactly this
Your AI agent taps into the entire Vinkius MCP catalog to handle these for you. You describe what you need. It does the rest.

Frequently Asked Questions About This MCP Server Orchestration
Which MCP servers do I need for this workflow?
Three: Langfuse, Helicone and Google Sheets. Connect all three to your AI client before running any prompt from this page.
Does this work with Claude Desktop, Cursor or Windsurf?
Yes. Any AI client supporting the Model Context Protocol works , Claude Desktop, Cursor, Windsurf, Cline and others.
Do I need both Langfuse and Helicone?
Both provide unique data. Langfuse excels at trace-level quality and chain analysis. Helicone excels at cost attribution and usage patterns. Together, they give complete observability.
Is my LLM data secure?
MCP servers authenticate through API keys. Trace data stays in your Langfuse and Helicone accounts. Google Sheets stores aggregated analytics only. Vinkius does not store your LLM data.

MCP servers used in this workflow
Langfuse (LLM Tracing & Evals)
Langfuse (LLM Tracing & Evals) monitors your LLM apps. It lets your AI client track API calls, view detailed latencies, and manage prompt versions. You can attach human feedback or automated metrics to specific traces. It's for seeing exactly how your AI works, from token count to dollar cost.
Helicone (LLM Observability)
Helicone (LLM Observability) tracks your AI usage in real-time. Monitor requests, analyze costs per model or user, and measure latency across all LLM providers. You can also track multi-turn session graphs, manage prompt versions, and log user feedback directly through your agent. It gives you full visibility into your AI spend and performance.
Google Sheets
Google Sheets MCP Server lets your AI client read, write, and manage data directly in Google Sheets. Use conversational commands to pull data from specific ranges, append new rows, or structure entire spreadsheets. It acts as an analyst, letting you manipulate complex data without opening the GUI or writing formulas.
