Configure

Umami Cloud API base URL: https://api.umami.is/v1

Environment variables:

• UMAMI_API_KEY - Umami Cloud API key (required for Umami Cloud)
• UMAMI_USERNAME - Umami username (self-hosted only)
• UMAMI_PASSWORD - Umami password (self-hosted only)
• UMAMI_API_BASE (optional) - defaults to https://api.umami.is/v1

Auth rules:

• Umami Cloud: only UMAMI_API_KEY is supported.
• Self-hosted: you can use UMAMI_API_KEY or UMAMI_USERNAME + UMAMI_PASSWORD.
• You must configure at least one of these: UMAMI_API_KEY OR (UMAMI_USERNAME and UMAMI_PASSWORD).
• For self-hosted username/password auth, set UMAMI_API_BASE to your instance API root (e.g. https://your-umami.example/api).

All tool parameters that represent times accept ISO datetimes. If a datetime is missing a timezone, it is treated as UTC.
