Use Existing MCP Servers

Learn how to integrate popular MCP servers like Claude, Cursor, and Windsurf into your applications.

Using pre-built MCP servers​

In this guide, you'll learn how to:

  • Connect to public MCP servers - Integrate existing AI services into your applications
  • Configure authentication - Set up secure connections to third-party MCP servers
  • Make model-specific requests - Use specialized features of different AI models
  • Handle responses - Process and utilize the responses from various MCP servers

Overview​

TRMX AI allows you to use existing MCP servers in your applications without having to build your own. This approach lets you leverage pre-built, specialized AI capabilities with minimal setup.

Available MCP Servers​

These production-ready MCP servers offer specialized AI capabilities:

  • Claude: Advanced natural language understanding and reasoning
  • Cursor: Specialized code completion and generation
  • Windsurf: Document processing, analysis, and extraction

Getting Started​

Prerequisites​

Before connecting to external MCP servers, you'll need:

  • The TRMX SDK installed (npm install @trmx/sdk)
  • API keys for the services you want to use
  • Basic familiarity with async/await JavaScript patterns

Integration Example​

Here's how to connect to and use various MCP servers:

// Import the TRMX client
const { TrmxClient } = require('@trmx/sdk');

// Initialize with your API key
const client = new TrmxClient({
  apiKey: process.env.TRMX_API_KEY
});

// Use Claude MCP server
async function askClaude(question) {
  const response = await client.connect('claude').ask(question);
  return response.text;
}

// Use Cursor MCP server
async function generateCode(prompt) {
  const response = await client.connect('cursor').generate({
    prompt,
    language: 'javascript'
  });
  return response.code;
}

// Use Windsurf for document processing
async function analyzeDocument(documentUrl) {
  const response = await client.connect('windsurf').analyze({
    documentUrl,
    tasks: ['summarize', 'extract_entities']
  });
  return response.results;
}

Authentication​

Each MCP server may require specific authentication methods. You'll typically need to:

  1. Register on the service's platform
  2. Generate an API key
  3. Include the key in your connection configuration

Security Best Practices​

When working with external MCP servers:

  • Store API keys in environment variables, never in code
  • Use proper error handling for service disruptions
  • Implement rate limiting to avoid unexpected costs
  • Consider fallback options if a service is unavailable
