Installation

npm install openmcp-sdk

Currently, openmcp-sdk only supports ESM-style imports.

Usage

Filename: main.ts

import { OmAgent } from 'openmcp-sdk/service/sdk';

// create Agent
const agent = new OmAgent();
    
// Load configuration, which can be automatically generated after debugging with openmcp client
agent.loadMcpConfig('./mcpconfig.json');

// Read the debugged prompt
const prompt = await agent.getPrompt('hacknews', { topn: '5' });    

// Execute the task
const res = await agent.ainvoke({ messages: prompt });

console.log('⚙️ Agent Response', res);

mcpconfig.json can be generated from openmcp client directly, you don't have to write it by yourself. Here is the example:

{
    "version": "1.0.0",
    "namespace": "openmcp",
    "mcpServers": {
        "my-browser": {
            "command": "mcp",
            "args": [
                "run",
                "~/projects/openmcp-tutorial/crawl4ai-mcp/main.py"
            ],
            "description": "A MCP for long-term memory support",
            "prompts": [
                "hacknews"
            ]
        }
    },
    "defaultLLM": {
        "baseURL": "https://api.deepseek.com",
        "apiToken": "sk-xxxxxxxxxxxxxx",
        "model": "deepseek-chat"
    }
}

Run your agent and get example output:
