When to pick ni-c/caldav-mcp
Events, tasks and journal entries over CalDAV, on any server that speaks the standard — Radicale, Baikal, Nextcloud, SOGo, Fastmail, iCloud. 22 tools. 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

Developer toolkit: auto-detect stack for AI context files, catch port conflicts, validate .env schemas, spot docs drift, audit dependency licenses, and time coding tasks — 7 MCP tools, one install.
