Maxima MCP Server

An MCP server for interfacing with the Maxima Computer Algebra System (CAS) using the D language.

Overview

This project implements an MCP server that provides a stateless interface to Maxima through batch mode execution. Each command runs in isolation with proper resource management and timeout handling. The server uses the D-MCP server library for MCP protocol implementation.

Features

• Stateless batch mode execution
• Configurable execution timeout
• Complete output capture (stdout/stderr)
• Automatic resource cleanup
• Temporary file-based execution
• Process isolation per command
• Quiet mode operation
• UUID-based temporary file management

Requirements

• D compiler (DMD, LDC, or GDC)
• DUB package manager
• Maxima CAS installed and available in the PATH
• D-MCP server library (located at ../d-mcp-server)

Building

dub build

Running

./bin/maxima-mcp

Usage

Once the server is running, you can use MCP clients to connect and use the provided tool:

• run_maxima_code: Execute Maxima code in batch mode
  • Parameters:
    • code: The Maxima code to execute
  • Returns:
    • result: Complete output from Maxima execution

Batch Mode Operation

The server executes each command in isolation:

• Creates temporary file with unique UUID
• Launches new Maxima process in quiet mode
• Uses --batch flag for file execution
• Enforces configurable timeout (default: 30 seconds)
• Captures complete stdout/stderr output
• Ensures cleanup of temporary files and processes

Error Handling

• Timeout enforcement with configurable duration
• Process management with proper cleanup
• Temporary file cleanup using scope(exit)
• Complete output capture for error diagnosis
• Process termination handling
• Non-blocking output collection
