What is Filesystem MCP?

It is a simple filesystem MCP that allows an agent to create, read, update, and delete files within a specified root folder. It is intended for use with Claude (or other MCP clients) and requires Node.js >12.

How to use Filesystem MCP?

Install Node.js >12, then add the server to the Claude MCP configuration file (e.g., ~/Library/Application Support/Claude/claude_desktop_config.json) with the command node and args pointing to the built index.js and an absolute root folder path. Then start Claude and ask it to code a game – it will use the MCP to create, read, update, and delete files in the specified root folder.

Key features of Filesystem MCP
