How do I use FastFS-MCP?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@FastFS-MCP show me all Python files in my current directory" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

FastFS-MCP

A high-speed MCP (Model Context Protocol) server for filesystem operations, Git integration, and interactive prompting capabilities, designed to work seamlessly with Claude and AI-native tooling.

🚀 Overview

FastFS-MCP enables AI assistants like Claude to interact with your local filesystem, manage Git repositories, and provide interactive experiences through a standardized JSON-based protocol. Whether you're building AI-assisted development workflows, creating content with Claude, or automating file management tasks, FastFS-MCP provides the bridge between your AI assistant and your local environment.

💻 Installation & Quick Start

Docker Quick Start

# Build the Docker image
docker build -t fastfs-mcp .

# Run with your local filesystem mounted
docker run -i --rm \
  -v C:\\Users\\username:/mnt/workspace:rw \
  fastfs-mcp

On Unix/macOS: replace with -v $HOME:/mnt/workspace

With GitHub Authentication

Using Personal Access Token

docker run -i --rm \
  -v C:\\Users\\username:/mnt/workspace:rw \
  -e GITHUB_PERSONAL_ACCESS_TOKEN=ghp_your_token_here \
  fastfs-mcp

Using GitHub App (Option 1: Private Key as Environment Variable)

docker run -i --rm \
  -v C:\\Users\\username:/mnt/workspace:rw \
  -e GITHUB_APP_ID=your_app_id \
  -e GITHUB_APP_PRIVATE_KEY="$(cat path/to/private-key.pem)" \
  -e GITHUB_APP_INSTALLATION_ID=your_installation_id \
  fastfs-mcp

Using GitHub App (Option 2: Private Key from File in Workspace)

# First, copy your private key to the workspace
cp path/to/private-key.pem C:\\Users\\username\\github-app-key.pem

# Then run with the path to the private key
docker run -i --rm \
  -v C:\\Users\\username:/mnt/workspace:rw \
  -e GITHUB_APP_ID=your_app_id \
  -e GITHUB_APP_PRIVATE_KEY_PATH=/mnt/workspace/github-app-key.pem \

🔧 GitHub Authentication

FastFS-MCP supports two methods of GitHub authentication to enable secure Git operations with GitHub repositories:

Personal Access Token (PAT) Authentication

%%{ init: { "theme": "dark", "look": "handDrawn", "themeVariables": { "handDrawn": true } } }%%
sequenceDiagram
    participant Claude
    participant FastFS
    participant GitHub
    
    Claude->>FastFS: git_clone(private_repo_url)
    FastFS->>GitHub: Authentication with PAT
    GitHub-->>FastFS: Authentication successful
    FastFS->>GitHub: Clone repository
    GitHub-->>FastFS: Repository content
    FastFS-->>Claude: Clone successful

When a GitHub PAT is provided via the GITHUB_PERSONAL_ACCESS_TOKEN environment variable, Git operations that interact with GitHub (clone, push, pull, fetch) will automatically use the token for authentication, enabling:

Access to private repositories
Operations that require authentication (push, create repo, etc.)
Avoiding rate limits on API calls

GitHub App Authentication

%%{ init: { "theme": "dark", "look": "handDrawn", "themeVariables": { "handDrawn": true } } }%%
sequenceDiagram
    participant Claude
    participant FastFS
    participant GitHub
    
    Claude->>FastFS: git_clone(private_repo_url)
    FastFS->>FastFS: Generate JWT using private key
    FastFS->>GitHub: Request installation token with JWT
    GitHub-->>FastFS: Installation token
    FastFS->>GitHub: Clone repository with installation token
    GitHub-->>FastFS: Repository content
    FastFS-->>Claude: Clone successful

GitHub App authentication provides more granular permissions and better security compared to Personal Access Tokens:

Fine-grained permissions: GitHub Apps can be configured with specific permissions
Repository-specific access: GitHub Apps can be installed on specific repositories
Organization-level control: Organization admins can control which apps are installed
Automatic token refresh: Installation tokens expire after 1 hour and are automatically refreshed

To use GitHub App authentication, provide the following environment variables:

GITHUB_APP_ID: Your GitHub App's ID

And one of these options for the private key:

GITHUB_APP_PRIVATE_KEY: The private key content for your GitHub App (PEM format) as an environment variable
GITHUB_APP_PRIVATE_KEY_PATH: Path to a file containing the private key (PEM format)

Optionally:

GITHUB_APP_INSTALLATION_ID: The specific installation ID to use (if not provided, FastFS-MCP will attempt to use the first installation)

Security Considerations for Private Keys

When using GitHub App authentication, consider these security practices for managing private keys:

File-based private key (recommended):
- Store your private key in your workspace and use GITHUB_APP_PRIVATE_KEY_PATH
- Ensure proper file permissions (chmod 600) on the private key file
- This approach avoids having the key in process environment variables or shell history
Environment variable private key:
- Use this for development or when you can't mount a file
- Be aware that environment variables can be visible in process lists on some systems

🐳 Docker Environment

FastFS-MCP runs in a Docker container for portability and isolation, with the following tools installed:

ripgrep for high-performance file searching
jq for JSON parsing and manipulation
sed and gawk for text processing
tree for directory visualization
fd-find for alternative file finding
coreutils for standard Unix tools
zip/unzip, gzip, and xz-utils for compression
git for repository operations

🚀 Use Cases

AI-assisted development: Let Claude help you code, manage files, and use Git all within the same conversation
Content creation workflows: Enable Claude to read, write, and organize files for writing projects
Repository management: Get insights into Git repositories and automate common Git operations
Interactive project setup: Guide users through structured project initialization with interactive prompts
System administration: Perform file system operations and maintenance tasks with AI assistance

🔒 Security Considerations

FastFS-MCP provides direct access to your filesystem and Git repositories. Consider the following security practices:

Only run FastFS-MCP with appropriate file system permissions
Mount only the directories you need to expose to Claude
Use separate GitHub PATs with limited scope for authentication, or prefer GitHub Apps for better security
Regularly review the logs and commands executed by the server
For GitHub Apps, store the private key securely and use installation-specific tokens
When using GitHub App authentication, prefer file-based private keys over environment variables when possible
