Frequently Asked Questions

Technical questions regarding MCP, webhooks, and REST endpoints.

How do AI agents interact with the Model Context Protocol?

Slotwise implements an RFC-compliant Model Context Protocol (MCP) server at /mcp. LLMs like Claude and ChatGPT can call tool primitives (e.g. get_available_slots, create_booking) with zero client SDK boilerplate.

How are webhook payloads authenticated?

Every outbound webhook event includes an X-Slotwise-Signature header containing an HMAC SHA-256 hash computed with your webhook secret, ensuring tamper-proof delivery.
