fleet	Server framework for hosting A2A agents with MCP integration
agent-relay	Agent discovery and multi-agent communication
orc8	Dynamic orchestration for A2A agents with MCP tool support
symphony	Interactive CLI for managing multi-agent systems
create-agent	CLI tool to scaffold A2A agent projects
ask	Lightweight CLI chat client for A2A servers
load	Load agent definitions from files
agent-def	Standardized agent definition schema
types	Shared TypeScript types
mcp	MCP servers (bash, agent-relay)

Quick Start

Create an Agent

npx @artinet/create-agent@latest

Own every line

Server:

Serve intelligence in a couple lines. cr8 lets you quickly scaffold an AI agent without the headache.

import { cr8 } from "@artinet/sdk";

const { app } = cr8("My Agent")
  .text(({ content }) => `You said: ${content}`)
  .server.start(3000);

Messenger:

Talk to any agent. Messenger is an A2A protocol client, purpose built for multi-agent servers.

import { createMessenger, AgentMessenger } from "@artinet/sdk";

const messenger: AgentMessenger = createMessenger({
  baseUrl: "http://localhost:3000/a2a",
});

for await (const update of messenger.sendMessageStream("Hello!")) {
  console.log(update);
}

One protocol, Every framework

Cruiser docks agents from any framework onto artinet. Letting your OpenAI, Claude, and LangChain agents collaborate.

import { Agent } from "@openai/agents";
import { dock } from "@artinet/cruiser/openai";
import { serve } from "@artinet/sdk";

const openaiAgent = new Agent({
  name: "assistant",
  instructions: "You are a helpful assistant",
});

const agent = await dock(agent, { name: "My Assistant" });

await agent.sendMessage("Hello, World!");

Ship agents, not infrastructure.

Fleet is a lightweight server that deploys A2A AI agents, so you can focus on intelligence, not plumbing.

import { fleet } from "@artinet/fleet/express";
import { createMessenger, AgentMessenger } from "@artinet/sdk";

const flotilla = await fleet().ship([
  {
    config: {
      uri: "my-agent",
      ...
    },
  },
]);

flotilla.launch(3000);

const messenger: AgentMessenger = await createMessenger({ baseUrl: "http://localhost:3000/agentId/my-agent" });

await messenger.sendMessage("Hello, World!");
