Claude Text Editor MCP Server

- MCP Server Implementation: Follows the Model Context Protocol standard for AI tool integration
- File Operations:
- View file contents with optional line range specification
- Create new files
- Replace text in existing files
- Insert text at specific line numbers
- Undo previous edits

But using the tool name 'text_editor' to avoid name conflicts with built-in Claude tools.
