CalDAV Calendars

Host a copy with our keys and logs.

• CALDAV_URL — Root of the CalDAV server, e.g. https://dav.example.net. A calendar collection URL also works.
• CALDAV_USERNAME — Account name. Most hosted services want an app-specific password with it.
• CALDAV_PASSWORD — Password or app-specific password. Deleted from the environment once read.
• CALDAV_TOKEN — Bearer token, as an alternative to username and password. Not both.
• CALDAV_CALENDARS — Comma-separated calendars this server may touch, by path or final path segment. Default: all of them.
• CALDAV_TIMEZONE — IANA zone for timestamps that carry no offset, e.g. Europe/Berlin (default: UTC)
• CALDAV_USER_EMAIL — The address you are invited as, so respond_to_event can find your own attendee line
• CALDAV_MAX_EVENTS — Entries a listing returns by default, 1 to 500 (default: 100)
• CALDAV_READ_ONLY — Set to true to register only the read tools (default: false)
• CALDAV_INSECURE_TLS — Set to true to accept a self-signed certificate on the configured host only (default: false)
• CALDAV_ALLOW_PLAINTEXT — Set to true to allow a plain http:// URL to a host that is not loopback, which sends the credentials unencrypted (default: false)
• CALDAV_ALLOW_TOOLS — Comma-separated tool names or list_* prefixes to register; 'essential' selects a curated preset (default: all tools)
• CALDAV_DENY_TOOLS — Comma-separated tool names or list_* prefixes to remove from whatever the allow list left
• ELICITATION — Deliberately unprefixed, and reaches every MCP server in the environment. Set to false to make guarded tools use the two-call token instead of a dialog (default: true)
