The scope breakdown is the real takeaway here. Most MCP tutorials skip the local-vs-user-vs-project distinction, but it matters in practice. Local is great for quick experiments since there is no config pollution. User scope is what you reach for when Flux becomes a daily tool across all your repos. Project scope is the right call for team setups, and the env var placeholder is the right call there. What I find most useful about this guide is the Dev-Pro-Kontext workflow. It mirrors how developers actually iterate. Start exploratory, lock in a direction, then make surgical edits. The flux_edit_image tool is genuinely underused in most MCP setups. One thing worth adding: if you use project scope, consider documenting the expected env vars in a README or Makefile so new contributors know what to set up. That avoids the silent-failure case where claude mcp list shows flux as connected but the token resolves to nothing in CI.
