Use Flux Kontext Max from Claude Code

Flux Kontext Max is the premium tier of Black Forest Labs' editing-focused Flux line. Higher fidelity character and composition preservation than Pro, at double the credit cost.

If you use Claude Code and you want Flux Kontext Max available as a native tool that the agent can call directly, the AetherWave MCP server wires it up in one command. No SDK to learn, no separate API key per provider, no polling loop to write.

Quick facts

How to use it

Once the MCP is installed, you can ask Claude Code naturally. It'll pick Flux Kontext Max from the model-selection rubric in the tool description when your prompt matches its strengths (premium character-preserving edits).

Example interaction:

Claude Code calls aetherwave_edit_image with model: "flux-kontext-max" and returns the finished asset URL. The result auto-saves to your AetherWave gallery (Cloudflare R2 hosted, no URL expiration).
