About Calculator MCP server

Ever get frustrated when an AI confidently messes up a simple math problem? The Calculator MCP Server fixes that. It's an open-source Model Context Protocol server built specifically to give large language models a reliable, built-in calculator. Think of it as plugging a dedicated math coprocessor directly into your LLM's workflow. Instead of hallucinating numbers or struggling with complex arithmetic, your AI can now offload those precise numerical calculations to this specialized server. This is super useful for developers building AI agents that need to handle financial data, generate reports with accurate figures, or perform any task where getting the math right is non-negotiable. Setting it up means your projects gain consistent, trustworthy calculation abilities without forcing the language model to do what it's not best at. It cleans up a common weakness in AI interactions, making the whole system more dependable for you and the end-user. If you're working with MCP and need your AI to be numerically precise, this server is a straightforward solution that just works.

Documentation

Calculator MCP Server

An open-source Model Context Protocol (MCP) server that provides a calculator tool for Large Language Models (LLMs). It enables LLMs to perform precise numerical calculations by offloading math operations to this dedicated server.

Overview

This server implements the MCP standard to expose a calculate tool. When integrated with an MCP client, an LLM can send mathematical expressions to this server and receive computed results, improving accuracy over the model's internal math capabilities.

Key Features

  • Single Tool: Provides one calculate tool for evaluating mathematical expressions.
  • Precise Computation: Returns accurate numerical results for LLMs.
  • Standard MCP Interface: Connects via HTTPS using the standard MCP protocol.
  • Open Source: Based on the original mcp-server-calculator and licensed under MIT.

How to Use

To connect an MCP client (like Claude Desktop) to this server, add the following configuration. You'll need an Apify API token.

  1. Get your Apify API token from the Apify Console.
  2. Configure your MCP client with the server details:
{
  "mcpServers": {
    "calculator": {
      "url": "https://mcp-servers--calculator-mcp-server.apify.actor/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_APIFY_TOKEN"
      }
    }
  }
}

Note: Replace YOUR_APIFY_TOKEN with your actual token.

Input/Output

  • Tool Name: calculate
  • Input: A single required argument:
    • expression (string): The mathematical expression to evaluate (e.g., "2 + 2 * 3", "sqrt(16)").
  • Output: The numerical result of the evaluated expression as a string.

Connection & Resources

  • Connection URL: https://mcp-servers--calculator-mcp-server.apify.actor/mcp
  • For general MCP connection guidance, see the official docs: mcp.apify.com.
