intermediate Published 25 Mar 2026

Action Steps

Create a new TypeScript project using npm init to set up the environment
Install required dependencies like express and @mcp/core to handle REST and MCP requests
Configure express to handle REST requests and define routes for tool discovery and invocation
Implement MCP protocol using @mcp/core to handle agent requests and responses
Test the setup using tools like Postman for REST and MCP client libraries for agent interactions

Who Needs to Know This

Backend developers and architects designing microservices and agent-based systems can benefit from this approach to unify API interfaces
