mcp-langchain-ts-client

适用于模型上下文协议（Model Context Protocol）的LangChain.js客户端。

这是rectalogic/langchain-mcp到JS/TS LangChain和MCP API的移植。

安装

npm install mcp-langchain-ts-client

使用

const serverParams = {
  command: "npx",
  args: [
    "-y",
    "@modelcontextprotocol/server-everything"
  ]
}

// 初始化工具包
const toolkit = new MCPToolkit(serverParams);
await toolkit.initialize();

// 提取与LangChain.js兼容的工具
const tools = toolkit.tools;

// 使用这些工具
import { createReactAgent } from "@langchain/langgraph/prebuilt";
import { ChatAnthropic } from "@langchain/anthropic";

const llm = new ChatAnthropic({ model: 'claude-3-5-sonnet-20241022' });
const agent = createReactAgent({ llm, tools });
