Postman today announced that Claude, Anthropic's AI model, now powers Postman's Agent Mode. Developers can also access their Postman workspaces directly from Anthropic's developer tools, bringing API context into their AI-powered coding workflows.
As AI agents become central to how software is built, APIs are the infrastructure that makes them work. Postman sits at the center of how enterprises design, build, test, and govern those APIs. Together, Postman and Anthropic are giving developers a faster, smarter way to work across the full API lifecycle, built right into the tools they already use.
"Postman is where APIs are built, tested, and managed. Now it's where AI-native development happens too,” said Postman co-founder and CEO Abhinav Asthana. “Claude was the clear choice to power Agent Mode. Its coding performance and enterprise track record are unmatched, and Bedrock gives our customers the security and reliability they demand. The results speak for themselves: users engaging with Agent Mode show consistently higher usage, which tells us this is changing how developers work.”
Agent Mode is an AI-native assistant built directly into Postman and powered by Claude as the default model provider on Amazon Bedrock from Amazon Web Services (AWS). Unlike standalone AI tools, Agent Mode has the full context of a developer's workspace, collections, environments, tests, and underlying code, reducing manual work while maintaining organizational standards. Claude’s reasoning helps Agent Mode interpret API schemas and design patterns, allowing it to intelligently generate, test, and maintain APIs.
With Agent Mode, developers can generate API collections, tests, and documentation from an OpenAPI spec, debug failing requests by identifying errors and updating tests, keep Git, collections, and specs in sync without manual overhead, onboard new developers faster by surfacing relevant APIs, and access AWS MCP servers directly within Postman.
Amazon Bedrock provides the secure, enterprise-ready foundation that makes Agent Mode viable at scale. By running Claude through Amazon Bedrock, Postman customers benefit from centralized access controls, policy enforcement, auditability, and reliability for production workloads.
Postman's Claude Code plugin, Claude.ai MCP connector, and Cowork skill let developers bring Postman's API context directly into their agentic coding workflows. From within Claude, developers can search across Postman workspaces, generate idiomatic client code from private APIs, run API tests, create mock servers, audit API security, and keep collections in sync with their codebase.
"Developers at the world's largest companies already rely on Claude to build faster and more reliably. Postman is where many of those developers manage their APIs — having Claude power those workflows was a natural next step," said Sam Werboff, Head of Enterprise Tech GTM, Anthropic.
By combining the world’s leading API platform, one of the most trusted AI models, and a leading cloud provider, developers are equipped with the best tools they need across the entire API lifecycle.
