🔄 KaibanJS v0.21.0 – DeepSeek Integration + MCP Playground Examples

🌟 Highlight: DeepSeek Multi-Model Support + Model Context Protocol (MCP) in Playground

We’ve added official support for the DeepSeek provider with multi-model capabilities, allowing developers to use both deepseek-chat and deepseek-reasoner across agent workflows.

In addition, the React Playground has been upgraded to include DeepSeek llm examples and MCP (Model Context Protocol) examples, aligning with emerging standards for structured agent-tool interaction and enabling powerful, interoperable workflows.

📦 What’s New

🤖 DeepSeek Model Integration

• Introduced support for DeepSeek in agent llmConfig, with full support for:
• deepseek-chat

• deepseek-reasoner

• Updated the cost calculator and configuration system to reflect DeepSeek parameters

• Playground React app now includes DeepSeek-powered agent examples and enhanced Storybook demos

Agent using deepseek-chat:

:::js
const searchAgent = new Agent({
  name: 'Scout',
  role: 'Information Gatherer',
  goal: 'Find up-to-date information about the given sports input.',
  background: 'Research',
  type: 'ReactChampionAgent',
  tools: [searchTool],
  llmConfig: {
    provider: 'deepseek',
    model: 'deepseek-chat',
  },
});

Agent using deepseek-reasoner:

:::js
const profileAnalyst = new Agent({
  name: 'Mary',
  role: 'Profile Analyst',
  goal: 'Extract structured information from conversational user input.',
  background: 'Data Processor',
  tools: [],
  llmConfig: {
    provider: 'deepseek',
    model: 'deepseek-reasoner',
  },
});

🧰 Playground Enhancements

• Added DeepSeek examples to the React Playground
• Introduced MCP (Model Context Protocol) examples to demonstrate agent-tool integration using standardized context formats

🧪 Testing Improvements

• Updated tests to include DeepSeek agent workflows
• Validated configuration across DeepSeek, OpenAI, and Anthropic agents
