mathgraphs-mcp

MCP server for interactive math graphing, 3D scene building, and presentations.

MathTalking computes and renders interactive visualizations. Plot 2D functions, geometry, and 3D scenes. Results are graph-verified — roots, extrema, and intersections are computed from actual plotted curves, not generated by AI.

Zero install. Browser-native. Every result is a shareable interactive URL.

Tools

plot_graph — 2D Math Visualization

Plot functions, points, segments, labels, and shapes on an interactive graph. Auto-computes roots, extrema, and intersections for plotted functions.

Input: Array of elements, each with a type and type-specific fields:

Supports: Explicit y=f(x), implicit x²+y²=1, parametric (cos(t),sin(t)), polar, piecewise, domain restrictions.

Optional params:

• viewport — {xmin, xmax, ymin, ymax}. Set it to your data's own magnitude; values far outside the range are invisible. Omit it and the server auto-fits the window to your elements.
• title — graph title
• summary — frosted glass overlay text on the graph
• gridStyle — "polar" (concentric circles + radial lines), "axes" (axes only), "none" (clean canvas)
• output — "url" (default, interactive page), "embed" (iframe URL), or "svg" (vector image)
• animations — array of {tool, name, from, to, loop} for animated parameters
• theme — "default", "terminal", "wallstreet", "science", or "finance"
• base_render_id — build on an existing render instead of re-sending every element
• remove_indices — drop elements from the base render by index (see get_graph)

Returns: Interactive URL with zoom, pan, and sliders. Auto-computed roots, extrema, and intersections in the response text, plus a graph check reporting anything that did not render properly — unreadable expressions, off-screen elements, duplicates, or a blank graph.

analyze — Precise Numerical Results

Compute exact values with the graph engine instead of doing the arithmetic in the model. Returns numbers, not a picture.

Input: type and f (both required), plus whichever fields that analysis needs:
