# MCP Filesystem Server
This MCP server provides secure access to the local filesystem via the Model Context Protocol (MCP).
## Components
### Resources
- **file://**
- Name: File System
- Description: Access to files and directories on the local file system
### Tools
#### File Operations
- **read_file**
- Read the complete contents of a file from the file system
- Parameters: `path` (required): Path to the file to read
- **read_multiple_files**
- Read the contents of multiple files in a single operation
- Parameters: `paths` (required): List of file paths to read
- **write_file**
- Create a new file or overwrite an existing file with new content
- Parameters: `path` (required): Path where to write the file, `content` (required): Content to write to the file
- **copy_file**
- Copy files and directories
- Parameters: `source` (required): Source path of the file or directory, `destination` (required): Destination path
- **move_file**
- Move or rename files and directories
- Parameters: `source` (required): Source path of the file or directory, `destination` (required): Destination path
- **delete_file**
- Delete a file or directory from the file system
- Parameters: `path` (required): Path to the file or directory to delete, `recursive` (optional): Whether to recursively delete directories (default: false)
- **modify_file**
- Update file by finding and replacing text using string matching or regex
- Parameters: `path` (required): Path to the file to modify, `find` (required): Text to search for, `replace` (required): Text to replace with, `all_occurrences` (optional): Replace all occurrences (default: true), `regex` (optional): Treat find pattern as regex (default: false)
#### Directory Operations
- **list_directory**
- Get a detailed listing of all files and directories in a specified path
- Parameters: `path` (required): Path of the directory to list
- **create_directory**
- Create a new directory or ensure a directory exists
- Parameters: `path` (required): Path of the directory to create
- **tree**
- Returns a hierarchical JSON representation of a directory structure
- Parameters: `path` (required): Path of the directory to traverse, `depth` (optional): Maximum depth to traverse (default: 3), `follow_symlinks` (optional): Whether to follow symbolic links (default: false)
#### Search and Information
- **search_files**
- Recursively search for files and directories matching a pattern
- Parameters: `path` (required): Starting path for the search, `pattern` (required): Search pattern to match against file names
- **search_within_files**
- Search for text within file contents across directory trees
- Parameters: `path` (required): Starting directory for the search, `substring` (required): Text to search for within file contents, `depth` (optional): Maximum directory depth to search, `max_results` (optional): Maximum number of results to return (default: 1000)
- **get_file_info**
- Retrieve detailed metadata about a file or directory
- Parameters: `path` (required): Path to the file or directory
- **list_allowed_directories**
- Returns the list of directories that this server is allowed to access
- Parameters: None
## Features
- Secure access to specified directories
- Path validation to prevent directory traversal attacks
- Symlink resolution with security checks
- MIME type detection
- Support for text, binary, and image files
- Size limits for inline content and base64 encoding
## Getting Started
### Installation
#### Using Go Install
```bash
go install github.com/mark3labs/mcp-filesystem-server@latest
```
### Usage
#### As a standalone server
Start the MCP server with allowed directories:
```bash
mcp-filesystem-server /path/to/allowed/directory [/another/allowed/directory ...]
```
#### As a library in your Go project
```go
package main
import (
"log"
"os"
"github.com/mark3labs/mcp-filesystem-server/filesystemserver"
)
func main() {
// Create a new filesystem server with allowed directories
allowedDirs := []string{"/path/to/allowed/directory", "/another/allowed/directory"}
fs, err := filesystemserver.NewFilesystemServer(allowedDirs)
if err != nil {
log.Fatalf("Failed to create server: %v", err)
}
// Serve requests
if err := fs.Serve(); err != nil {
log.Fatalf("Server error: %v", err)
}
}
```
### Usage with Model Context Protocol
To integrate this server with apps that support MCP:
```json
{
"mcpServers": {
"filesystem": {
"command": "mcp-filesystem-server",
"args": ["/path/to/allowed/directory", "/another/allowed/directory"]
}
}
}
```
### Docker
#### Running with Docker
You can run the Filesystem MCP server using Docker:
```bash
docker run -i --rm ghcr.io/mark3labs/mcp-filesystem-server:latest /path/to/allowed/directory
```
#### Docker Configuration with MCP
To integrate the Docker image with apps that support MCP:
```json
{
"mcpServers": {
"filesystem": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"ghcr.io/mark3labs/mcp-filesystem-server:latest",
"/path/to/allowed/directory"
]
}
}
}
```
If you need changes made inside the container to reflect on the host filesystem, you can mount a volume. This allows the container to access and modify files on the host system. Here's an example:
```json
{
"mcpServers": {
"filesystem": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"--volume=/allowed/directory/in/host:/allowed/directory/in/container",
"ghcr.io/mark3labs/mcp-filesystem-server:latest",
"/allowed/directory/in/container"
]
}
}
}
```
