v1.2.0

Released: April 5, 2026

Highlights​

  • Knowledge module extracted — moved to a standalone @toolpack-sdk/knowledge package; toolpack-sdk integrates via duck-typing
  • ESM-first dual build — ESM primary with CJS compatibility; 52% smaller package (186 KB → 38 KB) via minification and tree-shaking
  • MCP client support — connect to external MCP tool servers via stdio or HTTP
  • Full Windows CI — all test matrix combinations pass on Windows

Breaking changes​

Knowledge module moved to @toolpack-sdk/knowledge​

// Before (v1.1.0)
import { Knowledge, MemoryProvider } from 'toolpack-sdk/knowledge';

// After (v1.2.0)
import { Knowledge, MemoryProvider } from '@toolpack-sdk/knowledge';

Install the new package:

npm install @toolpack-sdk/knowledge

SDK integration is unchanged — Toolpack.init({ knowledge: kb }) still works via duck-typing.

toolpack-sdk​

MCP client​

const toolpack = await Toolpack.init({
  provider: 'anthropic',
  mcp: {
    servers: [{ transport: 'stdio', command: 'npx', args: ['-y', '@my-org/mcp-server'] }]
  },
});

Build improvements​

  • ESM (dist/index.js) + CJS (dist/index.cjs) + TypeScript declarations
  • Minification, disabled source maps, sideEffects: false for tree-shaking
