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.
Collaboration
Work in the same session with people and agents
MCPCalc collaboration is built around saved sessions. Once a suite tool is saved, you can share one link for live editing and another for safe read-only viewing.
Save a suite workspace
Click Save & Share to turn your scratchpad into a persistent session.
Share the collaborative link for live editing
Send the live-edit link when you want someone to work in the same session with you.
Use the read-only link when edits should stay locked
Share the read-only link when people should see the work but not change it.
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.
