What is the ROC AUC Evaluator MCP Server?
The Area Under the Receiver Operating Characteristic Curve (ROC AUC) is a vital metric for evaluating binary classification models. Because it involves sorting probabilities and integrating the area under a curve iteratively, Large Language Models are mathematically incapable of calculating exact AUC scores from raw arrays. The ROC AUC Evaluator offloads this task to local Node.js processes, instantly returning mathematically rigorous AUC metrics using the exact trapezoidal rule.

Frequently asked questions
Why is calculating AUC difficult for LLMs?
AUC requires sorting an array of probabilities, stepping through each threshold, and integrating the True Positive Rate over the False Positive Rate. LLMs cannot perform reliable array sorting or integral math.
What format should the probabilities be in?
Provide a JSON array of actual labels (0 or 1) and a matching JSON array of predicted probabilities (floats between 0.0 and 1.0).
Is this identical to Python's scikit-learn AUC?
Yes, it uses the identical trapezoidal rule approach to compute the area under the curve deterministically.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your ROC AUC Evaluator MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
