Install

Hosted endpoint, so there is nothing to install. The probe connects straight to it:

https://mcp.posthog.com/mcp

Needs credentials: Authorization. The probe used placeholder values, so an amber needs credentials result below means the server asked for the real ones, not that it is broken. Maintainers: how to go green.
