PostHog
Hermoso is a marketing MCP server. Connect PostHog 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 PostHog
Per-user funnels, retention and session replay — the questions GA4 cannot answer. Replays come back as links you open in PostHog.

Connecting
Open the app, go to Workspace ▸ Connectors and connect PostHog. 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 PostHog through Hermoso?
Yes. The PostHog 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 PostHog 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.
