MatrixCalculator.net MCP

A remote Model Context Protocol (MCP) server for exact, step-by-step matrix calculations powered by MatrixCalculator.net.

Remote MCP endpoint

https://mcp.matrixcalculator.net/mcp

Official MCP Registry name

io.github.gamestarry/matrixcalculator-mcp

Current version: 0.1.0

What it does

MatrixCalculator.net MCP gives MCP-compatible AI clients access to six core matrix operations. Results preserve exact fractions and include structured calculation steps that an AI client can present as a short answer or expand into a detailed solution.

ToolDescription
matrix_addAdd two matrices with identical dimensions, with one step per entry.
matrix_subtractSubtract the second matrix from the first, with one step per entry.
matrix_multiplyMultiply compatible matrices using row-by-column steps.
matrix_determinantCalculate a determinant with row swaps, elimination steps, diagonal entries, and singularity information.
matrix_inverseCalculate an inverse with Gauss-Jordan row operations, singularity detection, and verification.
matrix_transposeTranspose a matrix and return the source position for every result entry.

Exact values

Inputs may be integers, decimals, or fraction strings:

2
0.5
-3
1/2
-7/4

Calculations use exact fraction arithmetic where possible. For example:

1/2 + 1/3 = 5/6

rather than converting the result to an approximate decimal.

Example requests

An MCP-compatible AI client can use the server for requests such as:

Add [[1/2, 2], [3, 4]] and [[1/3, 5], [-1, 6]] and show the steps.
Multiply [[1, 2], [3, 4]] by [[5, 6], [7, 8]].
Find the determinant of [[0, 1/2, 1], [2, 1, 3], [1, 4, 5]] step by step.
Find the inverse of [[0, 2, 1], [1, 1, 0], [2, 3, 4]] and verify the result.

The MCP server returns structured result data and detailed steps. The connected AI client decides how much of that detail to display to the user.

Connect

Use the following Streamable HTTP endpoint in any MCP client that supports remote MCP servers:

https://mcp.matrixcalculator.net/mcp

No API key is required for the current public V1 endpoint.

Health check

https://mcp.matrixcalculator.net/health

Local development

Requirements:

  • Node.js
  • npm
  • Cloudflare Wrangler

Clone and install:

git clone https://github.com/gamestarry/matrixcalculator-mcp.git
cd matrixcalculator-mcp
npm install

Run type checking:

npm run typecheck

Start the local Worker:

npm run dev

The local MCP endpoint is normally:

http://127.0.0.1:8787/mcp

Deployment

The production server runs on Cloudflare Workers.

npm run deploy

Production MCP endpoint:

https://mcp.matrixcalculator.net/mcp

About MatrixCalculator.net

MatrixCalculator.net provides matrix calculators, learning tools, and step-by-step matrix operations on the web.

This MCP project is maintained separately from the main website so MCP development and deployment do not affect the production calculator or its billing system.

Frequently asked questions

What is MatrixCalculator.net?

Exact matrix calculations with step-by-step results for six core matrix operations.

How do I install MatrixCalculator.net?

It runs as a remote server. In Claude Code: claude mcp add --transport http matrixcalculator-net 'https://mcp.matrixcalculator.net/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does MatrixCalculator.net need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is MatrixCalculator.net open source?

Its code is public on GitHub, but the repository does not declare a standard license.

Who maintains MatrixCalculator.net?

It is published by gamestarry. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
