What is the Native V8 MCP Server?
The Native V8 MCP Server routes AI agents like Claude, ChatGPT, and Cursor directly to Native V8 via 1 tools. Deterministically calculate True Positives, FP, Precision, Recall, F1-Score, and Accuracy local. Stop LLM hallucinations when evaluating model metrics. Powered by Vinkius — your credentials stay on your side of the connection, every request is auditable. Connect in under 2 minutes.
Built-in capabilities (1)
Tools for your AI Agents to operate Native V8
Ask your AI agent "Here are my actual labels: ['cat','dog','cat']. And predictions: ['cat','cat','cat']. Calculate the exact accuracy and confusion matrix." and get the answer without opening a single dashboard. With 1 tools connected to real Native V8 data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by Vinkius — your credentials never touch the AI model, every request is auditable. Connect in under two minutes.

Calculate confusion matrix on Confusion Matrix Engine
Provide arrays of labels. Calculates exact confusion matrix and accuracy from actual and predicted arrays
What the Confusion Matrix Engine MCP Server unlocks
Language models are probabilistic text generators, not calculators. When asked to evaluate classification arrays to produce F1-Scores or Precision/Recall metrics, they frequently hallucinate decimals and fail edge cases. The Confusion Matrix Engine offloads this critical Data Science task to a deterministic, local JavaScript runtime. It accepts arrays of actual vs. predicted labels and instantly computes mathematically perfect True Positives, True Negatives, False Positives, False Negatives, and overall Accuracy.
Frequently asked questions about the Confusion Matrix Engine MCP Server
Why not let Claude/GPT calculate the accuracy?
LLMs operate on tokens and probability distributions. If you give them 500 predictions, they might summarize or estimate the F1-score rather than calculating it exactly. This engine ensures 100% mathematical precision.
Does it support multi-class classification?
Yes, the engine automatically detects unique labels from both arrays and constructs an N-by-N confusion matrix, handling both binary and multiclass evaluations flawlessly.
Is there a limit to the array size?
The only limit is the standard Context Window limit for transmitting the JSON arrays. For arrays exceeding 100k items, consider chunking or local CSV aggregators.
