概览

What is MCP Chunk Editor?

MCP Chunk Editor is a Model Context Protocol server that enables LLMs to edit text files using semantically meaningful chunks (functions, classes, methods) rather than line numbers. It uses Universal CTags to parse files into chunks and provides immediate application of edits with preview. It is designed for AI-assisted code editing workflows.

How to use MCP Chunk Editor?

Install via pip install mcp-chunk-editor or run directly with uvx mcp-chunk-editor. Configure it in Claude.app by adding a JSON entry under mcpServers using the uvx, docker, or python command. Optionally set a custom --max-chunk-size argument (default 100 lines) to control chunk sizes.

Key features of MCP Chunk Editor

Semantic chunking using Universal CTags
Immediate change application with preview generation
Simple undo for the most recent change per file
Optimized for LLM token usage with incremental updates

Use cases of MCP Chunk Editor

An LLM reads a file’s function-level chunks, then replaces a specific method’s content
An LLM creates a new file with create_file and later deletes it with delete_file
An LLM edits a codebase chunk by chunk, undoing a change if the preview shows an error
