Emergent registers a custom MCP server from the standard mcpServers JSON config, including a command it runs for you. Hermoso ships as an npm package that starts its MCP server with one command, so the config is five lines and one key.

Before you start

Any Emergent account, and a Hermoso API key.
A Hermoso account. The free plan is enough to try it (see pricing). No account yet? Create one in the app first.

The steps

In Hermoso, open the MCP & CLI tab and create a key under Terminal & API keys. Copy it.
In Emergent, select the plus icon in the prompt box, then Advanced controls.
Open Select MCPs to use and choose New MCP Server. The same form is under Account Settings, Manage Agents, MCP.

Enter hermoso as the MCP Name, add a short description, and paste this as the JSON Configuration, with your key in place of the placeholder:

{
  "mcpServers": {
    "hermoso": {
      "command": "npx",
      "args": ["-y", "hermoso", "mcp"],
      "env": { "HERMOSO_TOKEN": "<your Hermoso API key>" }
    }
  }
}

Select Verify and Save. Hermoso now appears in the list of MCPs.
Switch hermoso on for the build, then name Hermoso in your prompt.

Emergent caches a server's tool list for a few minutes, so a tool that was just added shows up on the next job.

What the key lets it do

The key lets Emergent act as your Hermoso account: research ads, plan and make creative, and use your credits for paid actions. You can revoke it at any time in Hermoso, on the MCP & CLI tab under Terminal & API keys.

Connecting Hermoso does not connect your ad accounts or social channels. You add those inside Hermoso, under Workspace, Connectors, and only the ones you want. Ads are created paused, and nothing is posted or spent unless you ask for it.

The prompt

Use the hermoso connector: look at the app we just built, make three launch ads for it, and schedule one post a day this week on the channels I have connected.

Want more like that? The workflows are ready prompts for whole marketing jobs: competitor research into ads, ads from customer reviews, a week of scheduled posts, a paused Meta campaign.
