README

ChronoGate

Timezone and business-day truth for scheduling agents. LLMs guess at "now", DST and holidays; ChronoGate answers authoritatively: current time in any IANA zone, DST-safe conversion, relative expressions ("next Tuesday 3pm", "in 3 business days"), and public-holiday-aware business days for 100+ countries (via Nager.Date).

  • Remote MCP: https://chronogate-self.vercel.app/mcp (Streamable HTTP, JSON-RPC, protocol 2025-06-18, stateless)
  • Docs for agents: https://chronogate-self.vercel.app/llms.txt
  • Free tier: 200 calls/day per IP, no API key. Over the limit returns HTTP 402 (with buy link); resets 00:00 UTC. Paid tier coming.
