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 LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
