Filesystem MCP

🚀 File System Server Introduction

This project is a file system interaction server that adheres to the Model Context Protocol (MCP). Its primary function is to provide a secure, efficient, and comprehensive interface for AI agents to perform various file operation tasks.

🚀 Quick Start

The server adopts a modular design:

• Core Management Layer: Responsible for permission verification and operation legitimacy checks.
• File Operation Layer: Encapsulates specific file system calls.
• Network Communication Layer: Provides interfaces based on HTTP or WebSocket.
• Logging and Monitoring Layer: Records operation logs and provides real-time monitoring capabilities.

Installation

1. Install dependencies:

pip install zstandard python-multipart uvicorn[server,cli]

2. Initialize the configuration file:

cp config.example.yaml config.yaml && nano config.yaml

3. Start the service:

uvicorn server:app --host 0.0.0.0 --port 8000

Request Examples

List directory contents

GET /api/list HTTP/1.1
Host: localhost:8000
Authorization: Bearer <your-token>
Directory: ./examples

Write file content

POST /api/write HTTP/1.1
Host: localhost:8000
Authorization: Bearer <your-token>
Content-Type: multipart/form-data

-- boundary
filename=example.txt
content=hello world
-- boundary--

✨ Features

File Browsing and Inspection

• list_files and stat_items: List files and directories (supports recursion) and obtain multiple file status information.
• get_file_info: Get detailed information about a single file, including metadata and content summaries.

Content Reading and Writing

• read_content, write_content, and append_content: Implement reading, writing, and appending functions for multiple files, and automatically create parent directories.
• search_files: Search for keywords or regular expressions in multiple files and return matching results.

Precise Editing and Searching

• edit_file and replace_content: Support precise content modification (including insertion, replacement, and deletion operations) for multiple files, retain code indentation, and output change logs.
• search_files and replace_in_files: Implement cross - file text search and replacement, and provide context information for more accurate targeting of the content.

Directory Management

• create_directories: Create one or more directories, supporting recursive creation of parent directories.
• delete_items and move_items: Implement safe file and directory deletion, moving, and renaming operations.

Permission Control

• chmod_items and chown_items: Batch change the POSIX permissions and owner information of files and directories to ensure accurate permission settings.

Advantages

1. High Security
   All operations are restricted within the specified root directory to prevent out - of - bounds access.

2. Excellent Efficiency
   Supports batch processing of multiple files, significantly reducing communication overhead with AI agents.

3. Strong Reliability
   Each operation returns detailed execution results and error reports, facilitating debugging and problem troubleshooting.

4. Comprehensive Functionality
   Provides a rich set of operation interfaces covering the entire file lifecycle to meet various scenario requirements.

Design Philosophy

• Security First: Strictly limit all operations within the specified root directory.
• Efficiency Priority: Reduce resource consumption and latency through direct API calls.
• Simplicity and Clarity: Provide a clear and consistent MCP protocol interface for easy integration and use.
• Stability and Reliability: Each function is fully tested, and input parameters are strictly verified using the Zod schema.

Usage Scenarios

1. Code Repository Management

   • Perform automated file inspection and repair operations.

2. Content Generation Tools

   • Provide efficient multi - file reading and writing capabilities to accelerate the content generation process.

3. Data Processing Platforms

   • Implement complex data processing logic, including file filtering, conversion, and archiving.

📚 Documentation

FAQ

1. How to handle large files?

   • Supports chunked upload and download functions to ensure efficient processing of large files.

2. How to ensure security?

   • All operations are restricted within the preset root directory, and user permissions are strictly verified.

3. How to extend functionality?

   • New functions can be flexibly added through the plugin mechanism while keeping the core code concise.

Future Development

• Plan to develop support for long - connections based on WebSocket to improve the efficiency of real - time file operations.
• Consider adding version control functionality to facilitate the management of file change history.
• Explore the possibility of integrating with mainstream code repositories (such as Git).
