# 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
