Postman Partnership with Microsoft Expands AI Model Choice

Postman, a leading API platform, is partnering with Microsoft to expand AI model choice in Postman's Agent Mode, deepening integration across the Microsoft developer ecosystem through Postman's Model Context Protocol (MCP) server, and unveiling the general availability of a new API catalog integration with Microsoft Azure API Management.

Together, these announcements give enterprise development teams a unified, AI-powered path from API discovery to production, Postman said.

Agent Mode is an AI-powered assistant powered by knowledge of collections, tests, mocks, and specs and built directly into Postman so teams can streamline their API workflows.

Agent Mode gives enterprises reasoning capabilities from the top model providers alongside the security, compliance, and governance controls they require—all within the Postman platform they already trust, the company said.

Through this collaboration, Agent Mode now also supports OpenAI models on Microsoft Foundry, giving teams the flexibility to choose the model that best fits their workflow, security requirements, or organizational preferences. Foundry extends that choice without requiring teams to leave the platform. 

"Agent Mode isn't just a smarter way to work with APIs—it's a fundamental rethinking of how AI-native software gets built," said Abhinav Asthana, co-founder and CEO of Postman. "As enterprises move from AI experimentation to production, the question isn’t whether to use AI agents, it’s whether their APIs are ready for these agents. By expanding model choice through Microsoft Foundry and OpenAI, we're giving platform engineering teams the flexibility to bring the right AI to the right workflow without sacrificing the API context, test coverage, and governance guardrails that make agents trustworthy at scale. That’s what it means to be the platform where AI and APIs come together.” 

MCP server lets developers bring Postman's full API context directly into their agentic coding workflows across the Microsoft ecosystem. Rather than context-switching between tools, developers can now access Postman's capabilities from within the surfaces where they already work, the company said. From VS Code, GitHub Copilot, and Microsoft Foundry, developers can:

• Search across Postman workspaces to find APIs, collections, and environments instantly—without leaving their IDE or AI assistant
• Generate idiomatic client code from private APIs, grounded in the actual definitions in their Postman workspace
• Run API tests and catch issues before they reach production, surfacing results directly within the coding workflow
• Create mock servers and audit API security as part of an agentic pipeline, without manual tool-switching 
• Keep Postman collections in sync with their codebase, ensuring documentation and tests reflect the latest state of the API

The Postman MCP server is available now in Visual Studio Code and GitHub Copilot, with support surfaced through GitHub MCP Registry and Microsoft Foundry Tools. Support for Microsoft Copilot Studio is coming soon, extending these capabilities to no-code builders and enterprise automation teams building Copilot agents. 

Postman also announces the general availability of a new integration between its API platform and the Azure API Management API catalog.

Each API is ingested with full fidelity—including its name, version, description, OpenAPI spec, and associated environment metadata—so developers have everything they need to start building and testing immediately, with no manual re-entry or copy-pasting of specs. 

This integration enables enterprise teams managing large API portfolios across Azure infrastructure, providing a seamless bridge between governance tooling and day-to-day developer workflows, Postman said.

According to both vendors, Postman's integration with Microsoft Teams brings API collaboration into the conversations where decisions get made. With the Postman app for Teams, developers can share Postman collections, environments, and other workspace elements directly in Teams channels—with rich link previews that surface element name, type, and last-updated details alongside quick actions like commenting, watching, or forking a collection.

“Great software teams succeed when they have real context about their APIs and production systems. By integrating Postman with Microsoft Foundry and Azure API Management, developers can combine AI-powered workflows with enterprise-grade governance on a single control plane, from API design through production, so teams can move faster, reduce uncertainty, and build software that customers trust," said Yina Arenas, CVP Microsoft Foundry at Microsoft.
