Use FLUX.1 Kontext Max in your assistant

Paste this prompt into Claude Code, Codex, Cursor or any agent. It reads the guide and helps you connect.

Read https://flymy.ai/skill.md and https://flymy.ai/mcp/models/flux-kontext-max.md. Help me connect the FlyMy.AI MCP to this assistant, then run FLUX.1 Kontext Max (flymyai/flux-kontext-max) for this task: Replace the background of the photo I attach with a picnic blanket in a sunny park using FLUX.1 Kontext Max.

What FLUX.1 Kontext Max does

Kontext Max edits the input_image you give it from a prompt and keeps the rest of the picture as it was. It is the top Kontext tier for demanding edits and typography, slower and pricier than Kontext Pro. Set aspect_ratio, a seed, safety_tolerance (0 to 2) and prompt_upsampling.

FLUX.1 Kontext Max inputs

Every input of flymyai/flux-kontext-max as its live schema lists them. Returns output (file).

The agent calls get_model_schema, then run_model with:

{
  "endpoint_id": "flymyai/flux-kontext-max",
  "input": {
    "prompt": "Replace the background with a marble table by a sunny window",
    "aspect_ratio": "1:1",
    "seed": "1654",
    "prompt_upsampling": "true",
    "safety_tolerance": "2"
  }
}
