I would rather you know this up front than find out three steps in.
This is the plumbing. You do it once and it stays connected.
https://mcp.higgsfield.ai/mcp. Nothing else needs filling in, and you can ignore the advanced OAuth settings.https://, and check you are not already at your free-plan limit of one custom connector. If Claude adds the connector but never calls it, say so directly in the chat: "use the Higgsfield connector for this". It sometimes needs to be told the first time.This is the difference between a photo of someone who vaguely resembles you and a photo people think you actually took. Higgsfield calls it a Soul ID character: you feed it a set of your own photos, it learns your face, and then every image you generate afterwards keeps that face locked.
The photo set that actually works. Higgsfield's guidance plus what I learned making mine:
Back in Claude, in a chat with the Higgsfield connector on. Type or paste this, and Claude will run it through Higgsfield with your character attached.
Using my Soul ID character, create 4 Korean self-profile studio photos in the style of Seoul profile photo studios. Photorealistic, 4:5 portrait, one image per shot.
Keep my face, features, skin tone and proportions exactly the same as my character. Do not slim, reshape, lighten or smooth my face.
Look: clean seamless studio backdrop, soft diffused front light from a large beauty dish, gentle fill from below, no harsh shadows, a subtle healthy glow on the skin while keeping real skin texture, crisp focus on the eyes, 85mm lens at eye level.
Styling: natural no-makeup makeup with soft coral lips and straight natural brows, neat hair with a few soft face-framing strands.
Shot 1: chest-up, facing the camera, calm closed-mouth smile, soft grey backdrop, black blazer over a white tee.
Shot 2: slight head tilt, gentle smile, warm cream backdrop, crisp white shirt with the collar open.
Shot 3: shoulders angled 30 degrees, looking back at the camera, pale blue backdrop, fine-knit cardigan.
Shot 4: black and white close-up, chin slightly down, looking straight into the lens.
No text, no watermark, no props, no extra people.Why the prompt is built that way. The three lines doing the heavy lifting are the ones people delete. "Keep my face, features, skin tone and proportions exactly the same" stops the model quietly prettifying you, which is what makes an AI portrait stop looking like its subject. "Keeping real skin texture" stops the plastic finish. And naming a lens and a light source gives it a real photographic reference to copy instead of a vibe.
Once the character exists, you never do the setup again. These run off the same character and give you a full year of profile photos in one sitting.

No text, no watermark, no props, no extra people.These are for LinkedIn, Instagram, a speaker bio, a team page, a dating profile if you are upfront that it is a stylised photo. They are genuinely good for that.
The other honest note: these are generated images of you, not photographs of you. I would not post one as a "before and after", and I would not use one where someone is going to meet you in the next hour expecting that exact lighting. Used as what they are, a styled profile photo, nobody has a problem with it.
