Slack
Hermoso is a marketing MCP server. Connect Slack once and it becomes callable from Claude, ChatGPT, Claude Code, Cursor, Codex, Cline or the CLI — the same connection the web app uses, so nothing is duplicated and nothing is re-authorised per client.
What Hermoso does with Slack
A message in your channel the moment a render finishes or fails.
Driving it from an agent
Slack is reached through the tools of the account it is connected under, so it has no tools of its own name.
Connecting
Open the app, go to Workspace ▸ Connectors and connect Slack. One authorisation covers the web app, the MCP server and the CLI. See MCP & CLI for the endpoint and the client setup, or every channel we connect to.
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.
