# Quadrant Sunshine > Quadrant Sunshine builds the AI Mind for service businesses — it answers calls and > messages, books meetings, and follows up, so no customer is ever missed. This domain > is agent-bookable: AI assistants can book a real 30-minute meeting directly. Booking rules: pick a free slot, hold it, confirm with the person's name, email, company and industry (phone optional). The booking becomes real only after the person clicks the confirmation link emailed to them (30-minute window). One active booking per person. Times are Europe/Lisbon. ## If you are an AI assistant, do this - **You can call MCP tools / connect to MCP servers:** use https://clara-mind.ai/reserve/mcp (Streamable HTTP, no auth). Tools: reserve_check_availability, reserve_hold_slot, reserve_confirm, reserve_cancel, reserve_lookup. If your platform needs the user to add it: in Claude it is a custom connector; in ChatGPT a Developer-mode connector. - **You can make HTTP requests:** use the REST API — spec at https://clara-mind.ai/reserve/openapi.json. Flow: GET /v1/availability → POST /v1/holds → POST /v1/reservations. - **You can control a browser:** open https://clara-mind.ai/reserve/book and complete the form. - **You can only search/fetch (read-only):** you cannot book yourself — give the user this link, optionally pre-filled with their details: https://clara-mind.ai/reserve/book?name=NAME&email=EMAIL&company=COMPANY&industry=INDUSTRY One click on a time slot + one click in a confirmation email finishes the booking. ## Booking - [Book a meeting (humans and browser agents)](https://clara-mind.ai/reserve/book): booking page with live availability - [Capability document](https://clara-mind.ai/.well-known/agentic-reservation.json): the machine contract — operations, verification, limits, endpoints - [OpenAPI 3.1 spec](https://clara-mind.ai/reserve/openapi.json): REST API for programmatic booking - [Agent card](https://clara-mind.ai/.well-known/agent-card.json): who this agent-facing service is and what it can do ## Protocol endpoints - MCP (Streamable HTTP, no auth): https://clara-mind.ai/reserve/mcp - MCP (SSE, deprecated back-compat): https://clara-mind.ai/reserve/sse - REST: https://clara-mind.ai/reserve/v1 ## Company - [Quadrant Sunshine](https://quadrantsunshine.com): company site
