Postman MCP connector

Postman is an API platform for building, testing, and managing APIs throughout the development lifecycle. The Postman MCP connector allows AI agents to access and manage workspaces, create and modify APIs and their versions, and organize API collections. It also supports retrieving API metadata, deleting outdated API versions, and coordinating API development across team workspaces.

Authentication type

• API Key - Requires a static API key to be configured before the agent can connect to the service.

Uses

Use the Postman MCP connector to perform the following actions:

• Build and test APIs without writing code in Postman workspaces
• Organize API collections to standardize requests across teams
• Version API schemas and track changes over time
• Generate collections automatically from API schemas
• Link monitors, tests, and documentation to APIs for complete governance
• Merge API branches and sync schema changes across environments
• Create forks of collections for team collaboration and testing

Example prompts

Use the following example prompts to invoke Postman MCP connector tools from your AI assistant or Boomi Connect workflow:

• Show me all APIs in my Postman workspace.
• Create a new API called customer service in Postman.
• List all collections I have in Postman.
• Generate a collection from my API schema in Postman.
• Get all versions of my payment API in Postman.
• Delete the outdated user authentication API from Postman.
• Show me which tests are linked to my order API in Postman.
• Create a fork of the checkout collection for the payments team.
• Sync my schema with all related environments in Postman.
• Merge the payment processing API fork back to the main version.
