What is the Feature Scaler Engine MCP Server?
Neural Networks and K-Means clustering algorithms fail spectacularly if features aren't normalized. If an LLM attempts to subtract the mean and divide by the standard deviation across 5,000 rows, it will hallucinate 90% of the math.
This MCP brings deterministic Feature Scaling to your AI using simple-statistics. The AI specifies whether it wants Standard scaling (Mean=0, Variance=1) or MinMax scaling (Range 0-1), and the engine flawlessly transforms the target columns in milliseconds — returning the exact computed metrics for auditability.
The Superpowers
- Flawless Normalization: No LLM math hallucinations — exact scaling computed by your CPU.
- Multi-Column Support: Scale multiple features simultaneously in a single call.
- Automated Metric Extraction: Returns the exact Means, Std Devs, Mins, and Maxs used for scaling.
- Data Privacy: Your sensitive training data stays entirely on your machine.

Frequently asked questions
What is the difference between Standard and MinMax scaling?
Standard scaling (Z-Score) centers data at 0 with a variance of 1, ideal for algorithms that assume normally distributed features. MinMax compresses all values precisely between 0 and 1, ideal for neural networks and distance-based algorithms.
Are the computed scaling parameters returned for inverse transforms?
Yes. The JSON response includes the exact Mean and Std Dev (for Standard) or Min and Max (for MinMax) used to scale each column, enabling precise inverse transformations when needed.
Can it scale 10+ columns at once?
Absolutely. Pass a JSON array of all column names and they will all be scaled simultaneously in memory. The engine processes each column independently with its own computed metrics.
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 Feature Scaler Engine MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
