FLUX.1 Kontext Pro MCP: instruction edits with no API key

FLUX.1 Kontext Pro from Black Forest Labs edits a picture from a plain instruction: change the background, outfit or objects, and keep the rest. Run it from Claude Code, Codex, Cursor or any MCP client through one FlyMy.AI MCP, or call its API.

Use FLUX.1 Kontext Pro 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-pro.md. Help me connect the FlyMy.AI MCP to this assistant, then run FLUX.1 Kontext Pro (flymyai/flux-kontext-pro) for this task: Replace the background of the photo I attach with a rainy neon street at night using FLUX.1 Kontext Pro.

What FLUX.1 Kontext Pro does

Send an input_image and a prompt that says what to change. Kontext Pro is strong at targeted edits that leave everything else in place; for the hardest edits and text, use Kontext Max. Choose an aspect_ratio (1:1, 16:9, 9:16, 1:2, 7:3 or 3:7), a seed, safety_tolerance and prompt_upsampling.

FLUX.1 Kontext Pro inputs

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

Call FLUX.1 Kontext Pro from code

The same model, from an agent or from your own code. Keys stay in your FlyMy.AI account.

From an agent, through the MCP

The agent calls get_model_schema, then run_model with:

{
  "endpoint_id": "flymyai/flux-kontext-pro",
  "input": {
    "prompt": "Replace the background with a marble table by a sunny window",
    "aspect_ratio": "1:1",
    "seed": "42",
    "prompt_upsampling": "true",
    "safety_tolerance": "2",
    "input_image": "https://example.com/photo.jpg"
  }
}

From your code, over HTTP
