Coding With Perplexity AI

🚀 Perplexity MCP Server

A Model Context Protocol (MCP) server that uses the Perplexity AI API to provide intelligent code analysis and debugging capabilities. It seamlessly integrates with the Claude desktop client.

✨ Features

• Intelligent Error Analysis: Break down coding errors in detail and provide root cause analysis.
• Pattern Detection: Automatically identify common error patterns and offer targeted solutions.
• Comprehensive Solutions: Step - by - step repair procedures and multiple implementation alternatives.
• Best Practices: Include coding standards and error prevention techniques.
• Python Support: Specifically handle Python type errors and common coding issues.

💻 Usage Examples

Ask questions like:

• "How do I fix this TypeError in my Python code?"
• "What's causing this error message?"
• "How can I fix this code?"

Include your code snippet for targeted analysis:

def calculate_total(items):
    total = 0
    for item in items:
        total = total + item['price']  # TypeError: string + int

data = [
    {'name': 'Book', 'price': '10'},
    {'name': 'Pen', 'price': '2'}
]

result = calculate_total(data)

The server will provide:

1. Root cause analysis of the error.
2. Step - by - step solutions with code examples.
3. Best practices for preventing similar issues.
4. Alternative implementation methods.
