The Amplitude MCP from Hermoso is a hosted MCP server: connect Amplitude once and Claude, ChatGPT, Cursor or any other assistant you use can work in your Amplitude account for you. It is the same connection the Hermoso app uses, so you sign in once, and Amplitude sits next to the rest of the marketing Hermoso runs on autopilot for you.

Set up the Amplitude MCP

  1. Open the app, go to Workspace ▸ Connectors and connect Amplitude. One authorisation covers the web app, the MCP server and the CLI.
  2. Add the Hermoso MCP server to your assistant. The URL is https://app.hermoso.ai/mcp. In Claude: Settings → Connectors → Add custom connector, paste the URL, then sign in on the consent page. In Claude Code: claude mcp add --transport http hermoso https://app.hermoso.ai/mcp. There is no key to paste; the connector signs in with OAuth.
  3. Ask for what you want in plain words. The Amplitude tools are there with everything else Hermoso does.

Every other client and the CLI: MCP & CLI. Or see 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.

What is the Amplitude MCP server URL?

https://app.hermoso.ai/mcp. It is one hosted server for every channel Hermoso connects to, so there is no separate Amplitude server to install. Add it to your assistant as a custom connector and sign in with OAuth; no key to paste.
