      "Excerpt": "Hello Dominik, \n\nLove to see a calendar connector MCP server that supports a proper open standard (vs existing e.g. Google Calendar specific ones).\n\nI'd also like to wire up my address book. Since CalDAV and CardDAV are closely related, I was wondering if you could see such code living in this repo? I'd also be open to submitting PRs, but have to honestly admit that due to time constraints it would mostly be vibe coded.\n\nHappy to hear your thoughts.\nDavid",

This prevents AI models from querying events without specifying `end`, and when `null` or `undefined` is passed, it causes unpredictable behavior.\n\n> **Disclaimer**: I'm not a developer, so the technical analysis below may not be entirely accurate.

      "Excerpt": "Summary: The list-events tool's end parameter is required by the Zod schema, but when an LLM caller omits it (passing null), the MCP gateway sometimes strips the null silently (returning []) and sometimes passes it through (triggering a -32602 validation error). Making end optional with a sensible default would eliminate the inconsistency and make the tool significantly more ergonomic for multi-calendar workflows.\n\nObserved behaviour\nWhen calling list-events with end: null — which LLMs naturally",
