Exact matrix calculations with step-by-step results for six core matrix operations.
The publisher's own server: Calculator Tools MCP
Remote MCP server that performs six exact matrix operations and returns step-by-step calculations an assistant can show or expand.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
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/io.github.gamestarry%2Fmatrixcalculator-mcp/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.Add this to your client's mcpServers config.

Official MCP Registry name
Current version: 0.1.0
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.
Inputs may be integers, decimals, or fraction strings:
Calculations use exact fraction arithmetic where possible. For example:
rather than converting the result to an approximate decimal.
An MCP-compatible AI client can use the server for requests such as:
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.

Registry metadata is stored in server.json.
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.

Add two matrices of the same dimensions entry by entry. Useful for exact matrix addition or explaining each entry step by step. Accepts integers, decimals, and fraction strings (for example 1/2); returns the exact sum matrix and a calculation for each position.
matrixArequiredmatrixBrequiredSubtract matrix B from matrix A when both have the same dimensions. Useful for exact matrix subtraction, including negative values and step-by-step entry calculations. Accepts integers, decimals, and fraction strings; returns each exact difference and its calculation.
matrixArequiredmatrixBrequiredMultiply A by B when A's column count equals B's row count, including non-square matrices. Useful for exact matrix multiplication and step-by-step row-by-column dot products. Returns exact results plus each factor pair, product, and entry calculation; accepts fractions and decimals.
matrixArequiredmatrixBrequiredFind the exact determinant of a square matrix using fraction-preserving elimination. Use for determinant questions requiring row swaps, elimination steps, pivot multipliers, sign changes, diagonal products, or singularity checks. Returns the determinant and detailed operation steps.
matrixrequiredFind an exact inverse of a square matrix with step-by-step Gauss-Jordan elimination. Use for inverse questions needing exact fractions, augmented matrices, row swaps, normalization, elimination, and verification that A times A-inverse is identity. Returns the inverse and verification, or null with singular=true if not invertible.
matrixrequiredTranspose a rectangular or square matrix by exchanging rows and columns. Useful for requests to show where each result entry originated. Preserves exact integer, decimal, and fraction inputs and returns the transposed matrix with source-to-result position mappings.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
