AI assistant integration

Why connect Rio to your AI model?

General-purpose AI assistants know everything about the web, but nothing about your day. They cannot tell if you are free at 2pm on Thursday, cannot check your deadlines, and cannot move your workout when a meeting runs late.

Connect Rio over MCP and they can see your real tasks, calendar, habits and notes — and change them when you ask.

Frequently asked questions

What is Rio?

Rio is the AI personal secretary inside Meetrio. It manages your daily timeline, tasks, calendar events, habits and notes in one place.

What is the Model Context Protocol (MCP)?

The Model Context Protocol (MCP) is an open standard that enables AI models like Claude, ChatGPT, and Perplexity to securely interact with external tools and personal data sources.

What tools does the Rio MCP server provide?

Rio exposes two primary MCP tools: ask_rio for querying your calendar, tasks, habits, and notes (read-only), and tell_rio for creating tasks, scheduling events, setting reminders, and updating notes (write).

How is my personal data secured over MCP?

Access to your personal data requires OAuth authorization. Rio verifies access tokens and isolates your account's data. tell_rio can modify your data; confirmation prompts depend on your AI client's permission settings.

Can I use Rio MCP with multiple AI clients?

Yes. You can connect the same Rio MCP endpoint to Claude, ChatGPT, and Perplexity at once. Other clients work only if they support Streamable HTTP and OAuth 2.0 PKCE. All connected clients share your single Meetrio agenda.
