Install MCP Server

Use the one-click deeplink to install (requires Cursor and Container Use already installed): Install MCP Server

Add Agent Rules

Add the rules file to your project or home directory:
curl --create-dirs -o .cursor/rules/container-use.mdc https://raw.githubusercontent.com/dagger/container-use/main/rules/cursor.mdc

Verification

After setting up Cursor, verify Container Use is working:
  1. Check MCP Connection: Cursor should recognize Container Use tools
  2. Test Environment Creation: Ask Cursor to create a new environment
  3. Verify Isolation: Multiple environments should work independently

Troubleshooting

  • Verify the cu command is in your PATH: which cu
  • Check MCP configuration syntax
  • Restart Cursor after configuration changes
  • Ensure Docker is running and accessible
  • Check file permissions for configuration files
  • Verify cu stdio command works: echo '{}' | cu stdio
  • Check your Cursor MCP server logs
  • Verify Container Use tools are enabled in settings
