"A calculator for multiplying two numbers" matching MCP servers:

A deterministic Mastermind-style cipher lock exposed as MCP tools for benchmarking LLM reasoning and tool-use through a legible duel.

An MCP server that integrates the MathJS library to provide AI models with advanced calculation capabilities, including support for complex numbers, matrices, and unit conversions. It supports both stdio and HTTP transports for seamless integration with clients like Claude Desktop and GitHub Copilot.

A Model Context Protocol server that provides basic calculator functionality for LLMs, enabling them to perform mathematical operations like addition, subtraction, multiplication, division, modulo, and square root.

Enables LLM clients to perform arithmetic and advanced calculations through MCP tools, access math constants and session calculation history, and receive step-by-step guidance for solving equations.

Exposes basic calculator operations (add, subtract, multiply, divide, power, square root, modulus) through the Model Context Protocol.

Provides precise decimal arithmetic and Excel-style rounding for accounting and tax calculations via MCP protocol.

A simple MCP server that provides basic arithmetic operations like addition, subtraction, multiplication, division, power, and square root.

Enables an LLM client to perform basic arithmetic on two numbers — addition, subtraction, multiplication, and division — plus reverse a supplied text string, through five simple tools exposed over stdio. Inputs and structured text results follow JSON schemas, with invalid operations such as division by zero surfaced as tool errors.

Enables MCP clients such as Claude Desktop to perform basic arithmetic operations—addition, subtraction, multiplication, division, exponentiation, and square root—through exposed tools.

Enables AI agents to perform arithmetic operations — addition, subtraction, multiplication, and division with divide-by-zero validation — through MCP tool calls. It can be run locally over stdio or as an HTTP microservice via streamable-http transport.

Enables MCP clients and LLMs to perform basic arithmetic operations—addition, subtraction, multiplication, and division—through tool calls, including handling division by zero as an error.

MCP server enabling Claude Code to capture screenshots of Windows applications through WSL2, allowing AI to diagnose UI errors and verify layouts.

Enables MCP clients like Claude to query Chinese A-share market data, including K-line charts with forward/backward adjustment, limit-up and limit-down pools, per-stock fund flows, index quotes, and stock news, with automatic symbol normalization and retry handling for throttled data sources.

Provides A-share (Chinese stock market) quantitative analysis through tools for stock screening, northbound capital flow tracking, dragon-tiger list analysis, margin trading, sector analysis, technical indicators, IPO info, and limit-up/down statistics using akshare data.

MCP server for mathematical calculations with high-precision arithmetic, statistics, unit conversion, and financial math tools.

Provides mathematical computation capabilities including basic arithmetic operations (add, subtract, multiply, divide), advanced functions (square root, factorial, logarithm), and trigonometric functions (sin, cos, tan) through the Model Context Protocol.

Free MCP server for Claude with math and financial calculation tools — unit conversion, currency math, compound interest, statistics.

An MCP server that enables AI agents to pause and request human approval or information via Slack, Telegram, or macOS dialogs before proceeding with actions.

An MCP server for searching and downloading books from Library Genesis, supporting EPUB, MOBI, PDF, and more through natural language queries.

Read-only MySQL MCP server that lets AI agents list tables, describe schemas, and run SELECT/SHOW/EXPLAIN queries with a row cap, bound to a single database for safety.
