Package manager for the Cracking Shells ecosystem

Hatch

Hatch is a CLI tool for configuring MCP servers across AI host platforms. Adding a server to Claude Desktop, Cursor, VS Code, and others normally means editing separate JSON config files in different locations. Hatch does it from one command.

It also has a package system for managing MCP servers with dependency isolation, though that part is still being developed — see Getting Started for the current state.

Current status: suitable for development and trusted environments. Not hardened for production or multi-tenant use yet — see Security and Trust.

What it does

• Configure MCP servers on one or more AI host platforms at once
• Discover which host platforms are installed on your machine
• List and inspect server registrations across all your tools
• Manage MCP server packages with dependency isolation (system, Python, Docker)

Supported MCP Hosts

Claude Desktop, Claude Code, VS Code, Cursor, Kiro, Codex, LM Studio, Google Gemini CLI, Mistral Vibe, OpenCode, Augment Code (Auggie CLI and Intent)

Install

pip install hatch-xclam

Verify:

hatch --version

Or install from source:

git clone https://github.com/CrackingShells/Hatch.git
cd Hatch
pip install -e .

Usage

Configure MCP servers on your hosts

# Local server via npx — register it on VS Code
hatch mcp configure context7 --host vscode \
  --command npx --args "-y @upstash/context7-mcp"

# Remote server with an auth header — register it on Gemini CLI
export GIT_PAT_TOKEN=your_github_personal_access_token
hatch mcp configure github-mcp --host gemini \
  --httpUrl https://api.github.com/mcp \
  --header Authorization="Bearer $GIT_PAT_TOKEN"

# Register the same server on multiple hosts at once
hatch mcp configure my-server --host claude-desktop,cursor,vscode \
  --command python --args "-m my_server"

Inspect what is configured

# See all servers across all hosts
hatch mcp list servers

# See all hosts a specific server is registered on
hatch mcp show servers --server "context7"

# Detect which MCP host platforms are installed
hatch mcp discover hosts

Package management (in development)

The package system lets you install MCP servers with automatic dependency resolution and environment isolation. It is functional but being reworked for better integration with MCP registries.

hatch env create my_project
hatch env use my_project
hatch package add ./my_mcp_server
