Vennio
programmable scheduling for developers and AI agents
Vennio is scheduling infrastructure for developers and AI agents — the API is the product. A REST API plus an MCP server with 24 tools. Your app or agent can find availability, propose meetings, book time, and handle consent without anyone touching a calendar manually. Connect Vennio to Claude, GPT, or any MCP-compatible agent and it schedules on behalf of users in real time. Mutual scheduling, consent-scoped access, full webhook support. Not Calendly with an API bolted on.
Hey Product Hunt 👋
I'm Matty, founder of Vennio.
Most scheduling tools are designed for humans clicking buttons in a UI. Vennio is built for the opposite — code calling an API, or an AI agent calling MCP tools. The API is the product; the dashboard is optional.
What we ship today:
- REST API for the full booking lifecycle (availability, propose, book, cancel, consent, webhooks)
- MCP server with 24 tools — drop it into Claude, Cursor, or any MCP-compatible agent and it schedules on behalf of users
- Mutual scheduling — find when 2-5 people are all free without the back-and-forth
- Consent-scoped availability — your code can only see calendars the person has opted in to
I built this because every scheduling tool I tried treated "API" as an afterthought, and none of them worked properly with AI agents. If your app or agent needs to schedule meetings autonomously, this is for you.

Would love your feedback — especially from anyone building agents or AI-powered apps. What's the most painful scheduling problem you're trying to solve?
