No paid telephony, no extra API key for the conversation.

Writes are read-modify-write over the parsed card guarded by ETags, so an X- property some phone wrote in 2014 survives an edit; both group conventions are read and the one written follows what the book already uses; an address book allowlist is enforced where ids are decoded rather than per tool. Card text is treated as untrusted input, because a card claiming somebody's bank details changed does not need the model to run a tool, only to be believed. `npx -y @ni-c/carddav-mcp`

Recurring events are expanded client-side rather than trusted to the server, a calendar allowlist is enforced where ids are decoded, writes are read-modify-write guarded by ETags, and deleting or changing a whole series asks a person first. Calendar text is treated as untrusted input, because anyone who can send an invitation can put text in your calendar. `npx -y @ni-c/caldav-mcp`
