No official external-agent write API verified.\n\n**Nylas Calendar and Scheduler API.** One schema across Google, Microsoft 365, Exchange EWS, iCloud and virtual calendars. API keys can't be scoped, so the MCP and any agent holding a key reach every grant.\n\n## Before you call either\n\n### Cozi Family Organizer\n\n1. Use official read-only feeds for calendar visibility.\n2. Make edits in the originating calendar and allow for the refresh delay.\n\n### Nylas Calendar and Scheduler API\n\n1. Address calendar calls to /v3/grants/\u003cgrant_id\u003e, one grant per connected account\n2. List events in the window before retrying a create, since event writes have no idempotency key\n3. Point the MCP client at mcp.eu.nylas.com if the application lives in the EU region\n4. On 429, use the passed-through `Retry-After` if present, otherwise back off per grant\n5. Mint a short-lived API key for the agent with `expires_in` rather than sharing the main one\n\n## Questions\n\n### Which is better for AI agents, Cozi Family Organizer or Nylas Calendar and Scheduler API?\n\nNylas Calendar and Scheduler API scores 71 (BB) on agent readiness against Cozi Family Organizer's 15.7 (F), and leads in every scored category.\n\n### Can an agent call Cozi Family Organizer and Nylas Calendar and Scheduler API without installing anything?\n\nNo hosted endpoint is listed for Cozi Family Organizer.
