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"]
  }
}

    C2.3/5.0

    Scored across 1 tool

    Disambiguation5/5

    With only one tool, there is no possibility of confusion or overlap between tools; the single tool 'calculate' has a distinct and clear purpose for evaluating expressions.

    Naming Consistency5/5

    The single tool name 'calculate' follows a consistent verb-based pattern, and with only one tool, there is no inconsistency in naming conventions to evaluate.

    Tool Count2/5

    A single tool for a calculator server feels thin and under-scoped, as it lacks operations for common mathematical functions (e.g., add, subtract, trigonometric functions) or advanced features, making it borderline too few for the domain.

    Completeness2/5

    The tool surface is severely incomplete for a calculator domain; it only provides a generic 'calculate' tool without covering basic arithmetic operations, scientific functions, or memory features, leading to significant gaps in functionality.
