WolframAlpha MCP server

This MCP server integrates with the Wolfram Alpha API, allowing you to query Wolfram Alpha directly. It functions similarly to the "!wa" bang command in DuckDuckGo search, enabling you to solve mathematical problems, get scientific data, and access Wolfram Alpha's computational knowledge engine.

Installation and Setup

To use the MCP-wolfram-alpha server, you'll need to:

1. Obtain a Wolfram Alpha API key
2. Configure the server with your API key
3. Connect to the server

Obtaining a Wolfram Alpha API Key

First, get an API key from Wolfram Alpha. This server was tested with the full results API, but other API types might also work.

Server Configuration

You must set the WOLFRAM_API_KEY environment variable when configuring the server. Here's an example configuration:

{
    "mcpServers": {
        "MCP-wolfram-alpha": {
            "command": "uv",
            "args": [
                "--directory",
                "C:\\Users\\root\\Documents\\MCP-wolfram-alpha",
                "run",
                "MCP-wolfram-alpha"
            ],
            "env": {
                "WOLFRAM_API_KEY": "your-app-id"
            }
        }
    }
}

Make sure to:

• Replace "your-app-id" with your actual Wolfram Alpha API key
• Update the directory path to match your installation location

Using the Server

Available Functionality

The server provides these components:

Prompts

def wa(query: str) -> f"Use wolfram alpha to answer the following question: {query}"

Tools

def query_wolfram_alpha(query: str) -> str

Example Usage

To use the server, you can send queries that call the Wolfram Alpha API. For example:

• "What is the derivative of x^2?"
• "Calculate the distance from Earth to Mars"
• "Solve x^2 + 2x - 3 = 0"

The server will process these queries through Wolfram Alpha and return the results.

Inspecting the Server

For testing and debugging, you can use the mcp-cli-inspector tool:

npx @wong2/mcp-cli -c .\config.json

This allows you to interact with and test the server functionality directly from the command line.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "MCP-wolfram-alpha" '{"command":"uv","args":["--directory","C:\\Users\\root\\Documents\\MCP-wolfram-alpha","run","MCP-wolfram-alpha"],"env":{"WOLFRAM_API_KEY":"your-app-id"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "MCP-wolfram-alpha": {
            "command": "uv",
            "args": [
                "--directory",
                "C:\\Users\\root\\Documents\\MCP-wolfram-alpha",
                "run",
                "MCP-wolfram-alpha"
            ],
            "env": {
                "WOLFRAM_API_KEY": "your-app-id"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "MCP-wolfram-alpha": {
            "command": "uv",
            "args": [
                "--directory",
                "C:\\Users\\root\\Documents\\MCP-wolfram-alpha",
                "run",
                "MCP-wolfram-alpha"
            ],
            "env": {
                "WOLFRAM_API_KEY": "your-app-id"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
