Connect Hermoso to Base44

Base44 connects custom MCP servers once per account and supports OAuth. Hermoso is a remote MCP server with OAuth. Base44's own promotion tools post to LinkedIn, Instagram, Facebook and X and run Google ads; Hermoso adds TikTok, YouTube, Pinterest, Threads and more, ads on the other networks, and the image and video creative.

Before you start

• A Base44 account on the Builder plan or higher, which is where Base44 offers custom MCP connections.
• A Hermoso account. The free plan is enough to try it (see pricing). No account yet? Create one in the app first.

The steps

1. In Base44, click your workspace name at the bottom left of your account.
2. Click Account settings.
3. Click Builder and scroll to MCP Connections.
4. Click Add custom MCP. If you have already added a server, click Add MCP instead.
5. Enter Hermoso as the Name and https://app.hermoso.ai/mcp as the URL. Set Authentication to OAuth. Leave custom headers empty.
6. Click Authorize & Add, then sign in to Hermoso in the window that opens.

Base44's docs say MCP connections are used by the AI chat while you build and cannot be called from app flows, workflows or backend functions at runtime.

What you will be asked to approve

Your browser opens Hermoso's own page. It asks whether to let Base44 use your Hermoso account, under whatever name Base44 registers itself with. Sign in if you aren't already, then select Allow. That is the only thing you approve. It lets Base44 research ads, plan creative and generate images and video on your account, the same things you can do in the app. There is no key to copy, and you can take it back any time in the Hermoso app, 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.

A prompt to try

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.
