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": {

Runtime guide

cloud

Hosted runtime

Hosted servers run from a provider-managed environment. You usually connect the MCP client to the hosted endpoint or follow the provider's authorization flow, without keeping a local process alive

  1. Open provider connection page
  2. Authorize or copy endpoint
  3. Connect from your MCP client
terminal

Local runtime / other methods

Local servers run on your own machine or infrastructure. You normally copy the server_config into your MCP client, install the required package, and provide env variables from env_schema when needed

  1. Copy server_config
  2. Install required package
  3. Fill env variables and restart client
