About Filesystem MCP Server
Filesystem MCP Server exposes file and directory information and file contents to MCP clients. It provides metadata and content resources, a directory-listing tool, and uses Spring Framework for dependency injection.
Key features
- 01Retrieve file and directory metadata
- 02Read text and binary file contents
- 03Detect MIME types from extensions
- 04List directory files
- 05Use Spring dependency injection
Use cases
- 01Inspect file and directory details
- 02Read files through an MCP client
- 03List files in a directory
MCP support
It exposes file metadata and content as MCP resources, and provides a `list_files` tool for directory listings.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project READMEFilesystem MCP Server
An MCP server that provides resources for accessing file metadata and content.
Overview
The Filesystem MCP Server is a Model Context Protocol (MCP) server that provides resources for accessing file metadata and content. It allows clients to retrieve information about files and directories, as well as read the content of files.
Features
- Get metadata for files and directories (name, path, size, timestamps, permissions, etc.)
- Read the content of text and binary files
- Automatic MIME type detection based on file extension
- Comprehensive logging
- Dependency injection using Spring Framework for better maintainability and testability
Resources
The server provides the following resources:
file://metadata/{path}- Get metadata for a file or directoryfile://content/{path}- Get content of a file
For more information, see the resources documentation.
Tools
The server provides the following tools:
list_files- List files in a directory
For more information, see the tools documentation.
Building and Running
Prerequisites
- Java 17 or higher
- Maven
- Spring Framework (automatically managed by Maven)
Building
mvn clean package
This will create an executable JAR file in the target directory.
Running

Architecture
The server uses a layered architecture:
- Configuration Layer: Spring configuration classes for dependency injection
- Service Layer: Core services for file system operations
- Resource Layer: MCP resources for exposing file system functionality
- Utility Layer: Utility classes for common operations
Dependency Injection
The server uses Spring Framework for dependency injection, which provides:
- Constructor injection for better testability
- Lifecycle management with
@PostConstructand@PreDestroy - Configuration classes for explicit bean definitions
- Component scanning for automatic bean discovery

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
