Claude Text Editor MCP Server

An open-source implementation of the Claude built-in text editor tool as a Model Context Protocol (MCP) server. This package provides the same functionality as Claude's built-in text editor tool, allowing you to view, edit, and create text files through a standardized API.

Features

Identical API to Claude's Text Editor: Implements the exact same interface as Claude's built-in text editor tool
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

Supported Claude Text Editor Versions

This package implements an equivalent tool to the built-in Claude text editor tool versions:

text_editor_20241022 (Claude 3.5 Sonnet)
text_editor_20250124 (Claude 3.7 Sonnet)

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