Overview

AI-generated overview

A remote calculator server for grade, GPA and test-score arithmetic, letting an assistant compute percentages, needed final scores and weighted averages.

What you can do
Compute percent and letter grades from questions wrong on an assignment or test, plus grading-scale tables with sources. Calculate the score needed on a final exam to reach a target grade. Work out weighted averages across categories. Estimate GPA and SAT, ACT or MCAT practice-test scores. Each result comes with a one-line method and a link line.
When to use it
Useful when a student or teacher wants quick grade, GPA or test-score math while chatting with an assistant, such as checking what a final exam score would be needed or how a weighted grade works out. It is for practice and planning rather than official records.
Requirements
A remote endpoint at calculatorforgrading.com over streamable HTTP; no package, account, API key or environment variable is declared. Only numbers and letters are needed as input.
Before you install
Results are estimates for practice and planning, not official grades or scores. Letter cut-offs differ by school, so the scale used should be stated and checked against the syllabus. The server asks that names, student IDs and school names not be supplied.

Installation

In SourceWeft

  1. Open Calculator for Grading in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.calculatorforgrading%2Fcalculatorforgrading/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
