Amplitude
Hermoso is a marketing MCP server. Connect Amplitude 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 Amplitude
Event segmentation, funnels with a conversion window, retention curves, and one person’s full activity stream — found by user id, device id or just the start of one.

Connecting
Open the app, go to Workspace ▸ Connectors and connect Amplitude. 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 Amplitude through Hermoso?
Yes. The Amplitude surface is exposed over one OAuth'd MCP endpoint, so Claude, ChatGPT, Cursor, Codex, Cline and the CLI can all drive it once the account is connected.
Do I need a separate Amplitude 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.
