Read, create, and edit files.

The io.github.domdomegg/filesystem-mcp MCP server performs filesystem operations, including reading, creating, and editing files. It is described as an MCP server for file access and modification tasks, with functionality intended to support workflows that interact with local folders and configuration files.

🛠️ Key Features

Read files
Create files
Edit files

🚀 Use Cases

Save email attachments (searches Gmail for matching emails, extracts PDFs, and saves them to a local folder)
Update config files (finds a config file, replaces an API endpoint URL, and shows a diff)
Generate reports (reads a calendar, formats a markdown summary, and saves it to a notes folder)

⚡ Developer Benefits

Supports automated file updates by showing diffs when replacing values in config files

⚠️ Limitations

No additional operational constraints (e.g., permissions, supported paths, safety checks, or error handling) are provided in the available data.

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).
