cedardiff MCP Server

Edit files with CEDARScript grammar rules

This is a TypeScript-based MCP server that implements CEDARScript, a SQL-like language for code manipulation. It provides:

- A comprehensive grammar for code manipulation commands
- Tools for executing CEDARScript operations
- Support for complex pattern matching and transformations

Features

Grammar

- SQL-like syntax for code operations (DDL, DML)
- Support for file, function, class, and method targeting
- Pattern matching with regex, prefix/suffix, and indentation rules
- Block-level code manipulation capabilities

Tools

- edit_file - Execute CEDARScript commands
- Takes script and working directory as parameters
- Supports file creation, deletion, moving, and updating
- Pattern-based code transformations

Implementation Status

Current testing has revealed:

- Command parsing works correctly
- Grammar supports complex operations
- File writing mechanism needs improvement
- Success messages returned but changes not persisted

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "cedardiff": {
      "command": "/path/to/cedardiff/build/index.js"
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.

ES Module Migration

The project has been migrated to use ES modules. Key changes include:

- Added "type": "module" to package.json
- Updated tsconfig.json to use "module": "ESNext"
- Converted import/export statements to ES module syntax
- Updated type definitions to be compatible with ES modules

Compatibility Notes

- Ensure you are using Node.js version 12 or higher
- Use import instead of require() for module imports
- Use .js extension when importing local files
