Frequently Asked Questions

Every calculator, the CAS workspace, and the spreadsheet have an “Embed” button that generates a ready-to-use HTML <iframe> snippet. Copy the snippet and paste it into your website’s HTML. The embedded calculator is fully interactive and works on any page that supports iframes.

The embed snippet includes width and height attributes you can adjust to fit your layout. The embedded view uses a clean, minimal style that blends well with most sites. You can also wrap the iframe in your own container to add borders, shadows, or other styling.

Yes. When you open the Embed dialog, check the box to include your current data — whether that’s the transcript in the CAS workspace, cell data in the spreadsheet, or form field values. The generated embed snippet will load with your data prefilled so visitors see it right away.

Use the “Share” button on any calculator to generate a link that captures your current inputs and results. Anyone who opens the link will see the same pre-filled calculator, ready to use or modify.

When your AI assistant has the MCPCalc MCP server installed, it can create a live session for any calculator or workspace. The assistant fills in values and runs computations, and you see the results update in real time in your browser. You can also make changes in the browser that the assistant can read back.

Yes. Once a session is created, the AI assistant can call get_session_state to read the current field values, computation transcript, and any changes you’ve made in the browser. This enables true two-way collaboration.

The MCP (Model Context Protocol) server lets AI assistants use MCPCalc’s calculators as tools. It exposes a JSON-RPC API that assistants can call to list calculators, run computations, create interactive sessions, and more — all without leaving the conversation.

Any assistant that supports the Model Context Protocol can connect to MCPCalc. This includes Claude (via Claude Desktop and Claude Code), ChatGPT (via plugin/MCP bridge), Cursor, Ollama, LM Studio, and others. See the Install page for setup guides.

Visit the Install page for step-by-step setup instructions for each supported assistant. Most setups only require adding a short JSON config snippet.

MCPCalc includes over 200 specialized calculators across finance, construction, health, math, science, and more. Each calculator has validated inputs, clear results, and can be used directly in the browser, embedded on other sites, or accessed by AI assistants through the MCP server.

The Computer Algebra System workspace at /math/cas supports symbolic and numeric math — simplify expressions, solve equations, differentiate, integrate, plot functions, and more. It uses Math.js and Nerdamer under the hood with LaTeX-rendered output.

The Name field sets the label shown next to your entries in the transcript. When you share a session and collaborate with others or with an AI assistant, each participant’s contributions are tagged with their name so you can tell who entered what. Your name is saved in your browser for future visits.

The Spreadsheet Calculator gives you a grid-based workspace with formula support, CSV import/export, and column formatting. It’s great for data analysis, budgeting, or any task that benefits from a spreadsheet layout.
