A Simple Directory Mcp tool

[DUCKLINGS-JS]

diff_tree (The State Anchor)

Standard ls doesn't have a memory. You run diff_tree first to set a baseline.
The Power: It saves a snapshot of your tree. If you tell Gemini to "fix the project structure," you run it again afterward. Gemini then gets a clear log of every file added or removed, making it way harder for the AI to lose track of its own changes.
2.

list_tree (Context-Optimized Visualization)

When a project has dozens of subdirectories, a raw ls -R floods the context window with junk.
The Power: This produces a clean, 3-level deep ASCII tree that automatically ignores node_modules, .git, and .cache. It gives Gemini the "big picture" without wasting your tokens on irrelevant folder nesting.
3.

build_tree (Shorthand Scaffolding)

Creating folders and files one by one via shell is slow. I built a simple grammar into this tool: folder>file<,next_file.
The Power: You can give Gemini one instruction: "Scaffold the core modules," and it executes a single tool call to build the entire skeleton. It’s faster, less prone to syntax errors, and keeps the conversation flow clean.

Read the source code/ask Gemini what it does, If you don't understand
