Qurak is a computational and mathematical engine for evaluating symbolic expressions and numerical problems. Available on the web, through an HTTP API, and as an MCP server, it lets people and AI assistants submit calculations and receive computed results. Its capabilities include calculus, differential equations, linear algebra, statistics, optimization, transforms, number theory, and two- and three-dimensional plotting. The workbench supports running expressions and reviewing calculation history, while plot outputs can be rendered as SVG.

Qurak serves a broad range of users, including students, educators, researchers, libraries, engineers, developers, quantum computing learners, and government teams. Researchers can use stateful sessions for derivations, models, and fits, and organizations can access usage statistics. Developers can connect through an API endpoint and token, while MCP compatibility enables tools such as Claude, Cursor, and VS Code to send calculations directly to the engine.

A free plan includes 20 evaluations per minute, a three-second computation budget, and access to both the MCP server and HTTP API, with no payment card required.
