Create a key

In the Hermoso app open MCP & CLI → Terminal & API keys and create a key. Grok Bot runs in its own sandbox with no browser, so the usual sign-in cannot open; the key is what signs it in. Never paste a key into a URL.

Ask Grok Bot to set it up

Paste this into the chat with your key and let it add Hermoso as a local (stdio) MCP server. This is the route verified end to end on Grok Bot; its Settings → Plugins catalog does not list Hermoso yet, and the URL connector route is blocked by a Grok Bot sign-in defect that xAI has not fixed.

Set up Hermoso for me so I can research ads, find creators, generate images and videos, and publish from here.
Add an MCP server of type stdio (a command), not a URL. Command: `npx -y hermoso mcp`. Environment variable: `HERMOSO_TOKEN` = the key I paste below. Do not put the key in a URL.
Key: <paste the key from app.hermoso.ai → MCP & CLI → Terminal & API keys>
Then run one real tool call: list my brands.

Start creating

Ask Grok Bot for “an image ad with Hermoso,” or “pull my competitors’ longest-running ads and remix the best one.”

Copy the connector URL

Open Plugins → Add → Create MCP App

Name it Hermoso, paste the URL as the Server URL, keep OAuth → Create. No Create MCP App? Switch on Developer mode under Settings → Plugins.

Connect & approve

Sign in with your Hermoso account on the consent page, and no key is needed. Then ask ChatGPT for “an image ad with Hermoso.”

Install Hermoso in Claude Code

Run this once in your terminal. It adds four Hermoso skills (research, ad-from-brand, generate, product-photoshoot) that run the hermoso command through npx, so no tool list is loaded into your sessions and nothing costs context until it runs. Already inside a session? Type /plugin marketplace add hermoso-ai/hermoso, then /plugin install hermoso@hermoso.

Sign in once

Opens your browser to sign in with your Hermoso account. Your agent runs this itself the first time it needs Hermoso, so you can also skip it. No browser on that machine? Use npx -y hermoso auth login --token <your key> with a key from MCP & CLI.

Copy the connector URL

Any client that takes an MCP server URL can use this one.

Or spawn it locally

Clients that launch a local process take this instead, which costs no context until a tool runs.

Neither shape fits?

There is a plain REST API at app.hermoso.ai/v1 with the same tools behind an hmk_ key, for an agent that speaks HTTP and nothing else.
