Asterai

The AI Agent Tool Marketplace.
Discover and deploy tools for your AI agents, written in any language.

✨ Overview

Asterai is an open-source platform and runtime for creating, sharing, and executing portable, sandboxed WebAssembly (WASI) components. Built around wasmtime, it provides a neutral compute substrate for the agentic era.

• Language Interoperability: Write tools in any language (Rust, Go, Python, JS, C/C++) — components written in different languages work together seamlessly via type-safe WIT interfaces
• Sandboxed Execution: AI agents can run untrusted code safely with WASI security guarantees
• True Portability: Deploy anywhere (local, cloud, edge) with no dependency hell — same behavior everywhere
• Instant Deployment: Tools just work without DevOps or container configuration

🚀 Installation

npm (recommended):

npm install -g @asterai/cli

Cargo (Rust users):

cargo install asterai

Binary releases: Download from GitHub Releases

🔧 CLI Command Reference

The CLI operates in two modes: local (offline, working with files in ~/.local/bin/asterai/artifacts) and remote (online, interacting with the Asterai registry API).

By default, most commands operate locally. To operate on the remote registry instead, pass the --remote or -r flag. This enables a git-like workflow where you modify locally and sync when ready.

Command	Local	Remote	--remote	Notes
Auth
auth login	✓			Stores API key to local file
auth logout	✓			Removes local API key file
auth status	✓	✓		Checks local file, validates against API
Environment
env init	✓			Creates local environment
env inspect	✓			Reads environment config
env add-component	✓			Adds component to environment
env remove-component	✓			Removes component from environment
env set-var	✓			Sets environment variable
env list	✓	✓		Shows local and remote environments
env run	✓	✓		Checks local first, pulls if not found
env pull		✓		Fetches from registry to local
env push	✓	✓		Pushes local to registry
env delete	✓	✓	✓	Deletes environment (-r for registry)
Component
component init	✓			Creates local component project
component list	✓			Lists local components
component pkg	✓			Packages WIT locally
component pull		✓		Fetches from registry to local
component push	✓	✓		Pushes local to registry
component delete	✓			Deletes local component

Legend:

• Local: Command reads/writes local files
• Remote: Command interacts with the Asterai API
• --remote: Pass -r or --remote to operate on the registry instead of locally
