SymPy Calculator MCP server

This MCP Calculate Server provides a powerful mathematical calculation service based on the Model Context Protocol and SymPy library, offering a wide range of symbolic computation capabilities from basic arithmetic to advanced calculus and matrix operations.

Installation Options

Installing via Smithery

The easiest way to install the Calculate Server for Claude Desktop is automatically via Smithery:

npx -y @smithery/cli install @611711Dark/mcp_sympy_calculate_server --client claude

Manual Installation

If you prefer to install the server manually:

1. Clone the repository:

   git clone https://github.com/611711Dark/mcp-calculate-server.git
   cd mcp-calculate-server
   

2. Create a virtual environment and install dependencies:

   uv venv
   source .venv/bin/activate
   uv pip install -e .
   

3. Add the following configuration:

   "calculate_expression1": {
      "isActive": false,
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/mcp_calculate_server",
        "server.py"
      ],
    }
   

Using the Calculate Server

The Calculate Server offers extensive mathematical functionality through the MCP protocol. You can call the calculate_expression tool by passing a mathematical expression as a string, and it will return the computed result.

Supported Operations

The server supports a wide range of mathematical operations:

Basic Operations

• Addition, subtraction, multiplication, division, exponentiation

Algebraic Operations

• Expression expansion, factorization, simplification

Calculus

• Differentiation, integration (both definite and indefinite), limit calculation

Equation Solving

• Algebraic equations, systems of equations

Matrix Operations

• Matrix inversion, eigenvalues/eigenvectors calculation

Series Expansion

• Taylor series expansion

Special Functions

• Trigonometric, logarithmic, exponential functions

Usage Examples

Here are some examples of the expressions you can calculate:

Basic Operations

"2 + 3*5" → 17

Algebraic Operations

"expand((x + 1)**2)" → x² + 2x + 1
"factor(x**2 - 2*x - 15)" → (x - 5)(x + 3)

Calculus

"diff(sin(x), x)" → cos(x)
"integrate(exp(x), (x, 0, 1))" → E - 1
"limit(tan(x)/x, x, 0)" → 1

Equation Solving

"solve(x**2 - 4, x)" → [-2, 2]
"solve([x**2 + y**2 - 1, x + y - 1], [x, y])" → [(0, 1), (1, 0)]

Matrix Operations

"Matrix([[1, 2], [3, 4]]).inv()" → [[-2, 1], [3/2, -1/2]]
"Matrix([[1, 2, 3], [4, 5, 6]]).eigenvals()" → {9/2 - sqrt(33)/2: 1, 9/2 + sqrt(33)/2: 1}

System Requirements

The Calculate Server requires the following dependencies:

• mcp>=1.5.0
• sympy>=1.13.3
• fastapi>=0.95.0
• uvicorn>=0.21.0

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 "calculate_expression1" '{"command":"uv","args":["run","--directory","/path/to/mcp_calculate_server","server.py"]}'

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": {
        "calculate_expression1": {
            "command": "uv",
            "args": [
                "run",
                "--directory",
                "/path/to/mcp_calculate_server",
                "server.py"
            ]
        }
    }
}

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": {
        "calculate_expression1": {
            "command": "uv",
            "args": [
                "run",
                "--directory",
                "/path/to/mcp_calculate_server",
                "server.py"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
