Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package filesystem-mcp
Claude Code 
claude mcp add filesystem -- npx -y filesystem-mcp@1.3.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "filesystem": {
            "command": "npx",
            "args": [
                "-y",
                "filesystem-mcp@1.3.0"
            ]
        }
    }
}
NPM package filesystem-mcp
Claude Code 
claude mcp add filesystem -e 'MCP_TRANSPORT=<MCP_TRANSPORT>' -- npx -y filesystem-mcp@1.3.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "filesystem": {
            "command": "npx",
            "args": [
                "-y",
                "filesystem-mcp@1.3.0"
            ],
            "env": {

            }

filesystem-mcp

MCP server for filesystem operations - read, create, and edit files.

Use Cases

Save email attachments: "Download all PDFs from my accountant's emails this month" → searches Gmail for matching emails, extracts attachments, and saves them to a local folder.

Update config files: "Change the API endpoint from staging to production in my config" → finds the config file, replaces the URL, and shows you the diff.

Generate reports: "Create a summary of today's calendar events" → reads your calendar, formats a markdown report, and saves it to your notes folder.

Code refactoring: "Rename the function getData to fetchUserData in src/api.ts" → reads the file, makes the precise replacement, and confirms the change.

Backup before changes: "Save a copy of my .zshrc before I modify it" → reads the current file and writes a timestamped backup.

Setup

Follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).
