# mcp-langchain-ts-client
A LangChain.js client for Model Context Protocol.
This is a port of [rectalogic/langchain-mcp](https://github.com/rectalogic/langchain-mcp) to the JS/TS LangChain and MCP APIs.
## Installation
```bash
npm install mcp-langchain-ts-client
```
## Usage
```typescript
const serverParams = {
command: "npx",
args: [
"-y",
"@modelcontextprotocol/server-everything"
]
}
// Initialize the toolkit
const toolkit = new MCPToolkit(serverParams);
await toolkit.initialize();
// Extract LangChain.js compatible tools
const tools = toolkit.tools;
// Use the tools
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 });
```
