📁Filesystem
Give Claude scoped read/write access to specific folders on your machine.
What it does
The Filesystem reference server gives Claude controlled access to your local files.
What it gives Claude:
- Read and write files
- Create, move, and delete files and directories
- Search and list directory contents
Access is scoped to the directories you pass on the command line — Claude cannot touch anything outside them. Swap /path/to/allowed/dir for the folder(s) you want to expose; pass several paths to allow more than one.
Installation
No API key needed, but you must pass at least one allowed directory path. Replace /path/to/allowed/dir with the folder you want Claude to access; add more paths separated by spaces to allow several.
- Make sure Claude is on your device and in your terminal.
MCP servers register with Claude Code via
claude mcp add. You need Claude Code installed first:npm i -g @anthropic-ai/claude-code - Set up the server on your machine.
Runs the project's installer (clone + dependencies + config). Follow any prompts. After this finishes, the server is ready to register with Claude Code in the next step.
- Restart Claude Code.
Quit and reopen Claude Code so it picks up the new MCP registration. Run
/mcpinside Claude Code to confirm the server is connected. - Use it.
Ask Claude naturally. It will call the server's tools when your request matches one. Tool calls show up inline so you can see exactly what Claude is doing.
