About Equation.io

Equation.io is an MCP server published by equation.io. Create interactive 2D and 3D graphs with validated equations, shareable links, and PNG previews.

It is hosted by the publisher at one address, so there is nothing to install: your AI client connects to it over the internet.

It asks for no keys or passwords.

Version 1.0.1 was published on 2 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on the registry entry and the live tool descriptions: 4 pass, 0 warn, 0 fail, 3 info. How we check.

What it asks for

This server declares no environment variables, so it asks for no keys or settings.
