Using Postman MCP in Antigravity: Code and Collections

Quick Overview

The video demonstrates how to use Postman's Managed Collection Protocol (MCP) server within the Antigravity environment to perform two primary functions: installing specific MCP tool configurations (like 'minimal', 'full', or 'code') and generating a Postman collection from local code, showcasing the ability to move from local application structure to a managed collection.

Key Points: Postman MCP server installation offers three main configurations: 'Minimal' (default, essential tools), 'Full' (all 100+ tools), and 'Code' (tools to generate high-quality client code). The speaker recommends the 'minimal' installation for general use as it stays below the 50-odd threshold for IDE support. To install an MCP server, the user modifies the configuration file to specify the desired option (e.g., ) and then refreshes the MCP server management screen in Antigravity. After installation, the speaker successfully lists existing collections, including 'Fleet Logistics API' and 'Planets API Collection', within the 'Quinton's Playzone' workspace. The second major use case demonstrated is code-to-collection generation, where Antigravity analyzes a local project directory (like 'fleet-web') to create a corresponding Postman collection, populating it with endpoints based on the code structure. The generated collection, named 'Fleet Logistics API - Generated', contained CRUD endpoints for Vehicles and Drivers, successfully demonstrating the workflow of deriving Postman assets directly from application code. The speaker highlights that this code-to-collection capability is crucial for enterprises needing to manage API specifications and artifacts securely within Postman.

Context: The video features Quinton Wall, Head of Developer Relations at Postman, providing a how-to guide on leveraging Postman's Managed Collection Protocol (MCP) server features within the Antigravity environment. Antigravity acts as a powerful IDE that integrates with the MCP server to manage collections, generate code, and streamline development workflows by connecting local codebases directly to Postman artifacts.
