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

Curve Fitting Engine for LlamaIndex
Every tool call from LlamaIndex 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 LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Curve Fitting Engine tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
