Shared model

The official SDK in this repository is the TypeScript package [`@frontal/sdk. It embeds the local Frontal CLI rather than calling a hosted HTTP API.

Option	Package or command	Best for
TypeScript SDK	`npm install @frontal/sdk`	Node.js applications and services
CLI	`npm install -g @frontal/cli`	Humans, scripts, and CI
MCP server	Expose a local Frontal engine to another MCP client over stdio.

Shared model

A thread is persisted conversation state.
A turn is one user request within a thread.
Items are structured results such as agent messages, reasoning summaries, command executions, file changes, MCP calls, web searches, and errors.
A stream is an async sequence of events emitted while a turn runs.

The SDK requires Node.js 18 or later. The package uses ES modules. Other languages can invoke the CLI or connect to the MCP server with their own wrapper.
