IDE extensions and AI agent integrations for Flox

Skills and MCP

Flox Agentic provides a skill library and MCP server that give AI coding agents expert knowledge of Flox environments, builds, services, containers, publishing, and CUDA.

Skills included: flox-environments, flox-services, flox-builds, flox-containers, flox-publish, flox-sharing, flox-cuda

Claude Code

The Flox plugin for Claude Code installs both the skill library and MCP server in one step:

claude plugin marketplace add flox/flox-agentic

claude plugin install flox@flox-agentic

Other agents (skills.sh)

For Cursor, Copilot, Windsurf, Gemini, and 15+ other agents, use skills.sh — a third-party open agent skills ecosystem:

npx skills add flox/flox-agentic

Third-party tool

skills.sh is not maintained by Flox. It requires Node.js. See skills.sh for supported agents and docs.

MCP server

For agents that support the Model Context Protocol directly, install the MCP server:

flox install flox/flox-mcp-server

Then point your client at the flox-mcp command using stdio transport. For Cursor, add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "flox": {
      "command": "flox-mcp"
    }
  }
}

Install from the Marketplace

Requirements

• Flox CLI installed (install instructions)
• VS Code 1.87.0 or later

1. Open the Extensions view (Cmd+Shift+X on macOS, Ctrl+Shift+X on Linux)
2. Search for Flox

Build and install from source

If you prefer to install manually, you can build a .vsix file from the source repository:

1. Clone the repository and check out a release tag:

   git clone https://github.com/flox/flox-vscode.git
   cd flox-vscode
   git checkout v1.0.1
   

2. Activate the Flox environment and build the package:

   flox activate
   npm run package
   

   This creates a .vsix file in the project directory.

3. Install the .vsix file using the Command Palette (Cmd+Shift+P on macOS, Ctrl+Shift+P on Linux):

   • Run Extensions: Install from VSIX…
   • Select the generated .vsix file

   Or install from the command line:

   code --install-extension flox-*.vsix
