CodeSnip MCP Server

An MCP server for making targeted code snippet edits in files.

Installation

npm install @patruff/server-codesnip

Usage

The server provides a single tool edit_snippet that can make precise edits to code files. It requires absolute paths to avoid confusion.

Example usage:

const request = {
    name: "edit_snippet",
    arguments: {
        filePath: "C:/absolute/path/to/your/file.py",
        oldSnippet: `def old_function():
    print("old code")`,
        newSnippet: `def old_function():
    print("new code")`
    }
};

Testing

The repository includes a test script (test_script.py) with a division function that needs a zero check, and a test harness (test.ts) that demonstrates how to use the MCP to fix it.

To run the tests:

npm run build
npm test
