What is the Folder MCP MCP server?

Most file and storage access work still happens through a UI a human drives. Folder MCP MCP server moves it into the conversation instead. Model Context Protocol server for folder operations and file system access.

The short version

A Model Context Protocol (MCP) server that provides tools for reading and analyzing folder structures, enabling LLMs to interact with local file systems safely and efficiently.

folder-mcp was created for a simple but powerful purpose: take your local folder and make it accessible to Large Language Models (LLMs) running anywhere. You don't need to upload your files to the cloud or use a third-party service.

  • Read files from specified folders with path validation
  • Security checks to prevent directory traversal attacks
  • Support for various file types and encodings
  • List all files in a folder recursively
  • Search files by name patterns (glob support)
  • Get folder information and metadata

Getting it running

npm on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

The tools it exposes

The server publishes 1 tool. What each one is for:

  • Dependencies — The Dependencies tool exposed by this server

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

Plenty of file and storage access servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Folder MCP's toolset — Dependencies — is a fair guide to whether it matches your workflow. It is maintained by okets; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
