Compatible with every major AI agent and IDE
What is the Curve Fitting Engine MCP Server?
LLMs can explain the concept of a line of best fit, but when they try to calculate actual slopes, intercepts, and R² scores on real data, they hallucinate wildly.
This MCP delegates regression logic to ml-regression locally. Provide the AI with arrays of X and Y coordinates, and the engine computes the mathematically flawless linear or polynomial equation. You get precise coefficients and a guaranteed R-squared accuracy score — all without touching a cloud API.
The Superpowers
- Zero Hallucination: Exact regression math performed locally by your CPU.
- Polynomial Precision: Fit multi-degree curves (quadratic, cubic, or higher) effortlessly.
- Automated R² Scoring: Generates the exact R-squared metric to validate model quality.
- Data Privacy: Your experimental and business data stays entirely local.
Built-in capabilities (1)
Perform exact deterministic curve fitting (Linear, Polynomial) on scatter plot data

How Vinkius secures
Curve Fitting Engine for Pydantic AI
Every tool call from Pydantic AI to the Curve Fitting Engine MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Does it calculate R-squared automatically?
Yes. Every regression model automatically returns the exact R-squared score. Values closer to 1.0 indicate a better fit, and the AI interprets this context for you.
Can I specify the polynomial degree?
Yes! When choosing the 'polynomial' type, specify any degree (2 for quadratic, 3 for cubic, etc.) and the engine computes all coefficients with exact precision.
Do the X and Y arrays need to be sorted?
No. The internal ML engine matches X[i] to Y[i] regardless of the order. The regression computation is independent of how the data is sorted.
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 Curve Fitting Engine MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
