Toolpack SDK

Core Packages:

Organizations:

Toolpack SDK is the open source TypeScript SDK for building production AI agents. It gives you everything you need in one package — tools, channels, cognition, and knowledge — without stitching together five different libraries.

Why Toolpack SDK?

• Production-Ready Agents - Build agents that run on Slack, Discord, Telegram, SMS, Email, Webhook, scheduled jobs, and MCP — 8 channel integrations out of the box
• 100+ Built-in Tools - File system, Kubernetes, command execution, web scraping, GitHub, database, diff, cloud, and more across 12 categories
• AgentMind Cognitive Layer - Persistent goals, beliefs, and reflections that survive across runs — the only TypeScript SDK with a built-in cognitive memory model
• Knowledge / RAG - Web crawling, REST API ingestion, hybrid semantic + keyword search, and streaming indexing across 6 source types
• Multi-Provider - OpenAI, Anthropic, Gemini, Ollama, OpenRouter — switch with one line, no vendor lock-in
• Workflow Engine - Automatic planning and step-by-step execution for complex multi-tool tasks
• Extensible at Every Layer - Custom tools, channels, provider adapters, agents, modes, and interceptors — if Toolpack doesn't have it built in, you can build it in using the same interfaces the built-in components use

Quick Example

import { Toolpack } from 'toolpack-sdk';

// Initialize with your preferred provider
const toolpack = await Toolpack.init({
    provider: 'openai',  // or 'anthropic', 'gemini', 'ollama'
    tools: true,         // Enable built-in tools
});

// Stream a response
const stream = toolpack.stream({
    messages: [{ role: 'user', content: 'List the files in the current directory' }],
    model: 'gpt-4o',
});

for await (const chunk of stream) {
    process.stdout.write(chunk.delta);
}
