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

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

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"] } }
