Math & Statistics Graphing Engine

Math & statistics graphing, computation, visualization and validation engine

Security Scan

The skill is internally consistent for a remote graphing/visualization plugin: it delegates computation to an external MCP server at the advertised domain and does not request unrelated credentials or local access — but it will send user data to that external service, so evaluate privacy before use.

Purpose & Capability

Name/description match the behavior in SKILL.md: the skill provides plotting, statistics, and interactive graphs and declares a single MCP server (mathtalking.com) to perform those tasks. No unrelated environment variables, binaries, or install steps are requested.

Instruction Scope

The instructions are scoped to plotting and statistical operations. They require sending graph/data to the declared MCP endpoint and always returning an interactive URL. The SKILL.md does not instruct reading unrelated local files or secrets, but it does direct the agent to transmit user-provided data to the external service for computation and rendering.

Install Mechanism

Instruction-only skill with no install spec or code files; nothing is written to disk by the skill itself. This is a low-risk installation model.

Credentials

No environment variables, credentials, or config paths are requested. The declared primary endpoint aligns with the stated purpose; there are no disproportionate secret requests.

Persistence & Privilege

always is false and the skill is user-invocable (normal). It can be invoked autonomously by the agent by default, which is expected and not by itself a concern. The skill does not request to modify other skills or system-wide config.

Assessment

This skill delegates computation and rendering to https://mathtalking.com/api/mcp and will send any graph data you provide to that remote service; using it is coherent for plotting but may expose sensitive data. Before installing or using the skill, verify you trust mathtalking.com (review its privacy/security policies), avoid sending secrets or regulated data in graphs, and prefer local/offline alternatives for sensitive datasets. Note that no local code was provided for review (instruction-only), so the static scanner had nothing to analyze — the main risk is data sent to the external server.

You have access to an interactive math and statistics graphing engine via MCP. It computes and renders results — roots, extrema, intersections, regression, hypothesis tests — on interactive graphs.

When to use this skill

• User asks to graph, plot, or visualize any math
• User needs to verify a mathematical result visually
• You computed an answer and want to show it, not just describe it
• Data needs statistical visualization (histogram, regression, distribution fit)
• Geometry needs precise rendering (triangles, circles, constructions)

Tools

plot_graph — Math Visualization

Plot functions, points, segments, labels, and shapes. Auto-computes roots, extrema, and intersections.

Element types:

• function: expression like "x^2-4", "sin(x)", "x^2+y^2=1", "(cos(t),sin(t))"
• points: array of {x, y} coordinates with optional label
• segment: line from (x1,y1) to (x2,y2) with optional arrow/dashed
• label: text at position (x, y)
• triangle: three vertices (x1,y1,x2,y2,x3,y3)
• box: edge + height for bar charts

compute_stats — Descriptive Statistics

Input: array of numbers. Returns mean, median, std, min, max, quartiles.

add_histogram — Histogram

Input: array of numbers. Auto-bins and draws bars.

add_regression — Regression

Input: array of {x,y} points. Fits linear/quadratic/exponential/power. Returns R².

fit_distribution — Distribution Fitting

Input: array of numbers. Fits normal/uniform/exponential. Returns best fit.

test_hypothesis — Hypothesis Test

Input: data groups + test type. Returns p-value with visual rejection region.

Important

• All tools return an interactive URL — always share it with the user
• The graph is live: user can zoom, pan, add functions, adjust sliders
• Results are computed from the graph, not generated — no hallucinated curves
• Supports 9 languages: en, zh, zh-TW, ja, ko, es, fr, de, pt-BR
