The Slack MCP from Hermoso is a hosted MCP server: connect Slack once and Claude, ChatGPT, Cursor or any other assistant you use can work in your Slack account for you. It is the same connection the Hermoso app uses, so you sign in once, and Slack sits next to the rest of the marketing Hermoso runs on autopilot for you.
What Hermoso does with Slack
A message in your channel the moment a render finishes or fails.
Just ask for it
Type it the way you would say it to a colleague. These are real things people ask for.
Send the finished render to Slack.
Post a summary of yesterday’s numbers to Slack every morning.
Everything Hermoso can do on Slack
Slack has nothing to learn. Connect it, then say what you want in plain language. Hermoso works out the rest.
Works wherever you already chat
It is one account, not one per app. Schedule something from Cursor and it shows up in your Hermoso calendar; draft a reply in Claude and it goes out from the same profile.

Frequently asked questions
Can an AI agent post to Slack through Hermoso?
Slack is reached through the account it is connected under rather than through tools of its own name.
Do I need a separate Slack connection for the app and for MCP?
No. One authorisation covers the web app, the MCP server and the CLI. It is the same stored connection.
What is the Slack MCP server URL?
https://app.hermoso.ai/mcp. It is one hosted server for every channel Hermoso connects to, so there is no separate Slack server to install. Add it to your assistant as a custom connector and sign in with OAuth; no key to paste.
