Step 3: Add the Server Configuration

Here’s what the filesystem server configuration looks like:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/Users/yourname/Documents",
        "/Users/yourname/Dev"
      ]
    }
  }
}

Replace the path arguments with directories you actually want Claude to access. The server will be limited to those directories — it can’t read files outside them. Start with one or two directories you’re comfortable with.

The command is npx because we’re using npx to run the package without a global install. The -y flag auto-accepts the package download. The paths after the package name are the allowed directories.
