Configure MCP servers at container startup using `claude mcp add-json`, so Claude Code picks them up natively. Skips servers already configured to avoid overwriting user customizations on restart. Also adds mcp.vaadin.com to the firewall allowed domains. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Tests that both Vaadin and Playwright MCPs are connected after container startup, and that the provisioning is idempotent (skips on second run). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Without CLAUDE_CONFIG_DIR exported, the claude CLI writes .claude.json to the home directory instead of the config directory that gets volume-mounted, breaking persistence across container restarts. Also switches the idempotency check from reading .claude.json directly to using `claude mcp get`, which respects the CLI's own config resolution.
