Intervals MCP server
Calendar, warm links, tasks — hosted MCP for agents
AI-powered calendar MCP — manage availability, events, tasks, reminders, and warm booking links via OAuth or API key at intervals.so/api/mcp.
Intervals is an AI-powered calendar app with a hosted Streamable-HTTP MCP at https://intervals.so/api/mcp. Agents can read availability, list and create calendar events, manage personal tasks and reminders, and create warm scheduling links for guests. Claude and ChatGPT connect with browser OAuth (no API key paste); Cursor uses a Bearer API key from the dashboard. Pro required. Same rate limits as the REST API (1,000 requests/day).
Calendar + availability
list_available_slots and list_events / create_event / cancel_event against the host Google Calendar.
Tasks and reminders
Create and complete personal tasks; schedule reminders that fire at a specific time.
Warm booking links
create_warm_link offers shareable availability to a guest without manually blocking calendar time.
OAuth or API key
Easy login for Claude/ChatGPT; Bearer ivl_live_… for Cursor. Docs at intervals.so/docs/mcp.
Who it’s for. Founders, operators, and agents that need to schedule meetings, protect focus time, and manage tasks from the MCP client — especially Intervals Pro hosts.

How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
