# Using Postman MCP in Antigravity: Code and Collections Source: https://www.youtube.com/watch?v=vf9qtpeB4xQ Recap page: https://rapidrecap.app/video/vf9qtpeB4xQ Generated: 2026-01-31T00:03:48.375+00:00 --- ## 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., `--minimal`) 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. ![Screenshot at 00:02: The Antigravity interface displays the "Antigravity - How To Guide" title while showing the 'Manage MCP Servers' screen, where the speaker previews the four main areas of exploration: MCP Server installation options, taking a collection to code, reverse code generation, and using Antigravity itself.](https://ss.rapidrecap.app/screens/vf9qtpeB4xQ/00-00-02.jpg) **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. ## Detailed Analysis The tutorial walks through two main capabilities of Postman's MCP server integration within Antigravity. First, it details the four installation options for the MCP server: Minimal (default, essential tools), Full (all 100+ tools), Code (tools for generating client code), and an implied fourth option for custom needs. The speaker prefers 'minimal' as it keeps the tool count low. Installation involves editing the `mcp_config.json` file to specify the desired flag (e.g., `--minimal`) and refreshing the 'Manage MCP Servers' view in Antigravity to confirm the installation. Once installed, the speaker uses the command `postman getCollections` to verify existing collections in the current workspace ('Quinton's Playzone'), showing collections like 'Fleet Logistics API' and 'Planets API Collection'. The second key demonstration is the code-to-collection workflow. After building a local React application named 'fleet-web' using Vite, the speaker prompts Antigravity to 'Analyze the fleet-web directory and create a Postman collection in my workspace,' specifically naming it 'Fleet Logistics API - Generated'. The demonstration confirms that Antigravity successfully analyzed the codebase and generated a Postman collection containing all necessary CRUD endpoints for Vehicles and Drivers, which is a critical feature for maintaining API governance and documentation directly from the source code. ### MCP Installation Options - Minimal (default, essential tools) - Full (all 100+ tools) - Code (tools to generate high-quality client code) - Installation involves setting a flag like `--minimal` in `mcp_config.json`. ### Verifying Installation - After installation, the speaker runs `postman getCollections` to list existing collections in 'Quinton's Playzone', confirming the server is active. ### Code-to-Collection Workflow Setup - The speaker uses a local Vite-built React app ('fleet-web') that consumes the Fleet Logistics API as the source for collection generation. ### Code-to-Collection Execution - The prompt instructs Antigravity to 'Analyze the fleet-web directory and create a Postman collection in my workspace,' naming it 'Fleet Logistics API - Generated'. ### Generated Collection Contents - The resulting collection automatically includes endpoints for Vehicles (Get, Create, Update, Delete, Tracking) and Drivers (Get All, Get by ID, Create, Update, Delete). ### Key Takeaway - The ability to generate Postman collections directly from existing application codebases ensures API documentation and testing assets remain synchronized with the source of truth. ![Screenshot at 00:02: The Antigravity interface displays the "Antigravity - How To Guide" title while showing the 'Manage MCP Servers' screen, where the speaker previews the four main areas of exploration: MCP Server installation options, taking a collection to code, reverse code generation, and using Antigravity itself.](https://ss.rapidrecap.app/screens/vf9qtpeB4xQ/00-00-02.jpg) ![Screenshot at 00:53: The mcp\_config.json file is shown, detailing the three Postman tool configurations \('Minimal', 'Full', 'Code'\) that can be selected during MCP server installation.](https://ss.rapidrecap.app/screens/vf9qtpeB4xQ/00-00-53.jpg) ![Screenshot at 02:25: The 'Manage MCP Servers' screen in Antigravity is empty, prompting the user to click 'Click here' to view the MCP server store or configure an existing one.](https://ss.rapidrecap.app/screens/vf9qtpeB4xQ/00-02-25.jpg) ![Screenshot at 04:23: The video transitions to showing the generated 'Fleet Management React Implementation Plan' on the right pane, detailing CRUD operations for Vehicles and Organizations, which resulted from the code-to-collection process.](https://ss.rapidrecap.app/screens/vf9qtpeB4xQ/00-04-23.jpg) ![Screenshot at 07:38: Inside Postman, the newly generated collection, 'Fleet Logistics API - Generated', is visible in the sidebar, containing structured endpoints for Vehicles and Drivers.](https://ss.rapidrecap.app/screens/vf9qtpeB4xQ/00-07-38.jpg)
