MCP Text Editor Server provides a Python-based interface for AI assistants to manipulate text files through a structured editing workflow. Built with FastMCP, it implements a two-step edit process with content verification using SHA-256 hashing to prevent conflicts during concurrent edits. The server offers tools for file management, content access, text search, and syntax validation for Python and JavaScript files. It enforces safety through line limits and automatic syntax checking before applying changes, making it ideal for collaborative code editing where multiple agents need controlled access to modify source files.

Reads text from the current file from start line to end line. Parameters: start (int): Start line number (1-based indexing), end (int): End line number (1-based indexing). Returns: Dictionary containing lines with their line numbers as keys, along with start and end line information.
Select a range of lines from the current file for subsequent overwrite operation. Parameters: start (int): Start line number (1-based), end (int): End line number (1-based). Returns: Dictionary containing the selected lines, line range, and ID for verification.
Prepare to overwrite a range of lines in the current file with new text. Parameters: new_lines (list): List of new lines to overwrite the selected range. Returns: Diff preview showing the proposed changes.
