Postman Unveils Fabric Gateway to Secure AI Agent API Interactions
Postman's new Fabric Gateway provides a protocol-agnostic control plane for governing AI agent access to APIs and MCP servers, addressing critical security gaps in enterprise AI adoption.
Postman has announced the general availability of its Fabric Gateway, a new control plane designed to manage how AI agents, large language models (LLMs), and Model Context Protocol (MCP) servers discover and interact with an organization's APIs and other tools. This solution aims to provide a centralized and secure method for enterprises to connect AI agents to their internal resources, ensuring that only authorized agents can access specific functionalities and data.
The rapid proliferation of AI agents in enterprise environments has exposed limitations in existing infrastructure, which was primarily built for human users and traditional applications. Gartner predicts that by 2029, 80% of organizations will need to significantly update or replace their current API gateways to accommodate the unique demands of AI workloads. The increasing complexity of AI interactions, including emerging protocols like MCP and agent-to-agent (A2A) communications, necessitates robust security measures to prevent unauthorized or unmanaged AI activities.
"If your agents cannot see or securely access your APIs, your business will become irrelevant," stated Abhinav Asthana, CEO of Postman. He emphasized the critical need for infrastructure that governs AI agent discovery, access, and authorization. Fabric Gateway is Postman's answer to this mandate, offering a control layer that allows enterprises to securely integrate AI agents with the APIs and services that underpin their business operations.
Fabric Gateway operates as a protocol-agnostic control plane, enabling organizations to route, govern, and observe LLMs, MCP servers, agents, and internal APIs through a single deployment within their own cloud environment. Unlike traditional API gateways that focus solely on runtime traffic, Fabric Gateway spans the entire lifecycle, encompassing API and agent discovery, design, identity management, policy enforcement, and overall governance.
Key features of Fabric Gateway include a unified registry that consolidates all agent-facing surfaces, APIs, CLIs, MCP servers, and agents under a single interface. This eliminates the need for fragmented, one-off integrations. The system enforces policies in a protocol-agnostic manner, ensuring consistent application of least-privilege principles regardless of the communication protocol, whether it be HTTP, gRPC, MCP, or A2A.
Furthermore, Fabric Gateway offers centralized oversight for security and platform teams, providing a single pane of glass to monitor agent actions, identities, and multi-agent collaborations. Built-in reliability features, such as fallback chains, circuit breakers, and health-aware routing, ensure that requests continue to flow even when a provider experiences degradation. The solution also incorporates compliance by design, authenticating, authorizing, classifying, and logging every interaction before it occurs, rather than relying on post-event audits.
This launch addresses a growing concern within the cybersecurity community regarding the security implications of AI agents. As these autonomous systems gain more access to sensitive data and critical business functions, the need for specialized governance and security tools becomes paramount. Fabric Gateway positions Postman as a key player in providing the necessary infrastructure to manage these risks effectively.
