Documentation
Find the right math tool fast
Choose a shared workspace to solve, graph, write, and explore math together or on your own.
Try a quick start
Start In The Suite
Six connected math tools
Open the suite first when the work may move between symbolic math, graphing, structured data, proof writing, and numeric verification.
Live Edit Session
Collaborative link
Use the collaborative link to work on problems together remotely in the same live session. Neither person needs to sign up for an account to open the link and follow the work.
Safe Review
Read-only link
Use the read-only link when you want to share your work on a blog, in social posts, or by email without letting readers edit the session. You can also use the embed calculator feature when you want that same work to live directly inside another page.
Agent Setup
Connect ChatGPT, Claude, or another MCP client
Once your assistant is connected to MCPCalc, it can open sessions, read the current tool state, and continue the same work you see in the browser.
Core Apps
The math suite is built around six connected tools
These six tools are the core of MCPCalc. Together they form an integrated math suite designed to make schoolwork and research more efficient and to help you learn along the way.
