Tool Calling
Tool calling is the mechanism by which a model invokes external software, such as a search index, a database query or a booking system, and uses the result in its answer.
Why It Matters
It is the bridge between a model that writes and a system that does, and it is where AI deployments meet existing enterprise software and its permissions.

- Model Context ProtocolThe Model Context Protocol is an open standard for connecting AI models to external tools and data sources through a common interface, so each integration does not have to be built from scratch.
- AI OrchestrationAI orchestration is the software layer that routes work between models, tools and people: choosing which model answers, in what order steps run, and where a human signs off.
