Tools and integrations
Function calling step by step, the Model Context Protocol, authentication and permissions for tools, channels such as WhatsApp, web chat, e-mail and voice, and webhooks, events and automations.
Tools are how agents act. This module explains the contract between a model and the systems it can call, and the ways users reach the agent.
- 1 Function calling step by step Follow a tool request from a model's decision through execution and back to an answer the user can trust.
- 2 MCP and tool standards Understand how a shared tool protocol reduces integration work without removing the need for permissions, trust and careful testing.
- 3 Authentication and permissions for tools Give an agent enough access to help a user without handing it the unrestricted authority of the whole organisation.
- 4 Integrating channels: WhatsApp, web chat, e-mail, voice Adapt one agent's knowledge and rules to different communication channels while preserving identity, conversation continuity and human support.
- 5 Webhooks, events and automations Build a clear mental model of event-driven work, scheduled tasks and the safeguards that keep repeated notifications from causing repeated actions.
