Quick Start

pnpm add @mokei/session @mokei/openai-provider

import { Session } from '@mokei/session'
import { OpenAIProvider } from '@mokei/openai-provider'

const session = new Session({
  providers: {
    openai: OpenAIProvider.fromConfig({
      apiKey: process.env.OPENAI_API_KEY
    })
  }
})

// Add an MCP server
await session.addContext({
  key: 'myserver',
  command: 'node',
  args: ['my-mcp-server.js']
})

// Chat with tool access
const response = await session.chat({
  provider: 'openai',
