Installation

Invokta is distributed as focused ESM packages. Start with @invokta/core, then install only the adapters and development tools your engine uses.

Requirements

• Node.js 22.20.0 or later
• An ESM project ("type": "module")
• A schema library that implements Standard Schema v1 and Standard JSON Schema v1

The examples use Zod 4 because it implements both schema contracts.

Install the core

npm

npm install @invokta/core zod

pnpm

pnpm add @invokta/core zod

Yarn

yarn add @invokta/core zod

Add execution channels

Install the CLI or MCP adapter when the engine needs that boundary.

npm

npm install @invokta/cli @invokta/mcp

pnpm

pnpm add @invokta/cli @invokta/mcp

Yarn

yarn add @invokta/cli @invokta/mcp

Package	Use it for
@invokta/core	Capabilities, engines, contracts, errors, and events
@invokta/cli	list, describe, and run commands
@invokta/mcp	MCP tools over stdio or stateless Streamable HTTP
@invokta/tooling	Capability-composition checks during development
@invokta/installer	Read-only inventory of supported local MCP client targets in its current release
@invokta/deploy	Reviewable container packaging and endpoint probes

ESM only

Invokta publishes native ESM entry points. Use import syntax and include file extensions in relative imports after TypeScript compilation, such as ./engine.js.
