Overview

Calculator MCP Server

The Calculator MCP Server acts as a connector, allowing Large Language Models (LLMs) to leverage a calculator for precise numerical computations. It exposes a `calculate` tool that accepts a string `expression` as input for evaluation. This server should be used when an LLM needs to perform accurate mathematical operations, ensuring reliable numerical outputs for tasks requiring precise calculations.

What it does

As an AI developer, I want to enable my LLM to perform accurate mathematical operations, so that it can provide reliable numerical answers.

I can install this server using pip with pip install mcp-server-calculator and run it using python -m mcp_server_calculator.

Alternatively, I can configure my MCP client to use this server by adding the following to my settings:

"mcpServers": {
  "calculator": {
    "command": "python",
    "args": ["-m", "mcp_server_calculator"]
  }
}
Source README

Calculator MCP Server

A Model Context Protocol server for calculating. This server enables LLMs to use calculator for precise numerical calculations.

Available Tools

  • calculate - Calculates/evaluates the given expression.
    • expression (string, required): Expression to be calculated

Installation

Using uv (recommended)

When using uv no specific installation is needed. We will
use uvx to directly run mcp-server-calculator.

curl -LsSf https://astral.sh/uv/install.sh | sh

Using PIP

Alternatively you can install mcp-server-calculator via pip:

pip install mcp-server-calculator

After installation, you can run it as a script using:

python -m mcp_server_calculator

Configuration

Using uv (recommended)

Add this to your MCP client settings:

"mcpServers": {
  "calculator": {
    "command": "uvx",
    "args": ["mcp-server-calculator"]
  }
}

Using PIP

Alternatively add this to your MCP client settings:

"mcpServers": {
  "calculator": {
    "command": "python",
    "args": ["-m", "mcp_server_calculator"]
  }
}
