Postman, the API platform used by more than 40 million developers and 500,000 organizations including 98% of the Fortune 500, announced it has achieved the Amazon Web Services (AWS) AI Competency in the Agentic AI Tools category. The designation recognizes Postman as an AWS Partner Network (APN) member with demonstrated technical proficiency and proven customer success in enabling organizations to build, test, and manage the APIs that power production-grade agentic AI systems on AWS.

The AWS AI Competency differentiates AWS Partners that have demonstrated deep expertise in enabling AI workloads capable of autonomous reasoning, planning, tool usage, and execution with the rigor and reliability enterprise teams require. Achieving this Competency reflects Postman’s role in the AI development stack: every AI agent depends on APIs, and Postman is how developers build, validate, and govern them at scale.

As part of its collaboration with AWS, Postman also introduced a new integration with Kiro, the AWS agentic IDE, along with deeper integrations across Amazon Bedrock and Amazon API Gateway. Together, these capabilities give enterprise development teams a more unified, AI-powered path from API discovery to production within the customer’s AWS environment.

“AWS gives incredible scale and flexibility, as enterprises manage APIs across more services, regions, and teams than ever before in an increasingly AI-powered world,” said Abhinav Asthana, co-founder and CEO of Postman. “Our collaboration is about bringing consistency and simplicity to that complexity, so teams can build, test, and manage APIs with AI embedded directly into the workflows they already rely on.”

Postman MCP Server Brings API Context into Kiro and the AWS Developer Community

Building on the momentum of its Kiro Powers launch partner announcement at AWS re:Invent 2025, Postman now delivers deep, production-ready integration with Kiro. Where that initial collaboration introduced developers to the vision of AI-native API workflows, release makes it actionable: developers can now access Postman directly within Kiro, eliminating the need to switch between tools while building and shipping APIs.

This is enabled by Postman’s MCP server, which brings full API context, including collections, environments, and tests, into agentic coding workflows across the AWS developer ecosystem.

From Kiro and other MCP-compatible surfaces, within a single workflow developers can:

• Search across Postman workspaces to find APIs, collections, and environments instantly
• 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
• 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 today in Kiro and any MCP-compatible environment.

Agent Mode, Amazon Bedrock, and Anthropic

Postman’s AI-native assistant, Agent Mode, is now powered by Anthropic Claude via Amazon Bedrock: a recently announced enhancement that provides the security, compliance, and data residency controls that enterprise teams require at scale. Embedded within Postman, Agent Mode understands the full context of a developer’s workspace, collections, tests, mocks, and specs, and can reason across all of it using Claude’s capabilities without data leaving the customer’s AWS environment.

Agent Mode works across the API lifecycle, including:

• Generate API collections, tests, and documentation directly from an OpenAPI spec
• Debug failing requests by identifying errors, updating tests, and rerunning in minutes
• Keep Git repositories, collections, and specs in sync without manual overhead
• Onboard new developers faster by surfacing which APIs to use and how they relate
• Access MCP servers directly within Postman without switching tools

API Catalog Integration with Amazon API Gateway Now Generally Available

Postman also announced the general availability of its API Catalog integration with Amazon API Gateway. Teams can now discover and import APIs from Amazon API Gateway directly into Postman with full context, including OpenAPI specs and environment metadata, eliminating manual re-entry and allowing developers to start building and testing.

From within Postman, teams can also view deployment status and history, monitor Amazon CloudWatch metrics per stage for operational insight, and export and deploy HTTP API definitions back to Amazon API Gateway. This integration creates a seamless bridge between governance tooling and day-to-day developer workflows, helping teams manage large API portfolios more efficiently.
