What this server does

The Filesystem MCP server is the foundational read/write surface for AI assistants. Every MCP user encounters it. Pick a directory; the server scopes all access to that root.

Tools included

  • read_file

    Read a file from the allowed root.

  • write_file

    Write or overwrite a file under the allowed root.

  • list_directory

    List entries in a directory.

  • move_file

    Move or rename a file.

The authoritative list comes from the server's tools/list at runtime. This catalog entry may lag the upstream until the next ToolPiper release.

Install in ToolPiper

ToolPiper handles the JSON configuration. Click Install, fill in any required tokens, and the server is ready in your chat.

Example prompts

  • "Read the notes I just dropped into the AIWorkspace folder and summarize them."

  • "Create a markdown file called 'meeting-notes-2026-05-19.md' with these bullet points."

  • "List the subdirectories under AIWorkspace and tell me which one was modified most recently."

Security notes

Network access is not granted. The server only reaches files under the directory you pick. Choose a workspace folder, not your home directory.
