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

Provides phone intelligence for AI voice agents, enabling inbound caller identification, outbound risk assessment, line type detection, and do-not-contact checks via four read-only MCP tools.

Enables AI agents to create, read, view, and edit Apple Numbers spreadsheets through the Model Context Protocol, leveraging both a parser engine and the Numbers application for formula evaluation and export.

Create, read and edit native Apple Numbers documents on macOS through 38 local MCP tools, using only the native scripting API. Preserves .numbers files and formatting, with formulas, custom templates, guided chart updates, CSV imports and PDF previews; MIT licensed, with no Excel conversion or Accessibility automation.

Number utilities MCP server providing base conversion, Roman numeral conversion, and English word spelling of integers.

Enables users to query Polymarket-vs-options probability comparisons, today’s disagreements, track-record scores, and implied probabilities for stock price levels through read-only MCP tools, plus a prompt for finding where the crowds disagree.

Current, source-cited US federal tax constants and freelancer calculators for tax year 2026, including the July 1 mid-year mileage change. Every response carries its IRS/SSA primary source and a last-verified date; refuses rather than guesses.

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 users to perform mathematical calculations through natural language by integrating an AI model with calculator tools via the Model Context Protocol.

An MCP server that exposes 16 calculator operations as tools, enabling arithmetic, rounding, and root calculations via natural language.

Enables AI agents to call tools through a security gateway that intercepts requests, enforces deterministic policy and risk checks, blocks or escalates high-risk actions for human approval, and keeps tool credentials and audit logs protected.

A cloud-deployable math tool server that provides calculator capabilities to local LLM agents via the Model Context Protocol and Server-Sent Events. It allows instructors to host a centralized calculation engine that students can connect to from their local development environments.

A deliberately broken calculator MCP server that always returns double the correct answer, designed as a learning exercise for MCP server implementation.

A Model Context Protocol (MCP) server example with calculator tools, built using FastMCP.

Provides four MCP tools for neural retrieval: personalized user recommendations, item-to-item similarity, cold-start text search, and explainable recommendation scores, enabling LLM agents to query a trained two-tower recommender over Amazon Reviews data.

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.
