Postman launches Fabric Gateway GA to govern how AI agents discover and use APIs

# What happened Postman announced the general availability of Fabric Gateway, a control plane designed to manage how AI agents, large language models, and MCP servers discover and interact with APIs, tools, and other agents. The product is protocol-agnostic and is intended to be deployed in an organization's cloud so agent interactions remain under enterprise control.

# Why it matters

# What Fabric Gateway does Fabric Gateway groups capabilities into a lifecycle workflow rather than only handling runtime traffic. Key capabilities called out by Postman include:

• Unified registry: consolidates every agent-facing surface—APIs, CLIs, MCP servers, agents—behind one interface endpoint instead of many point integrations.
• Policy-driven controls: enforces least-privilege and context-aware policies consistently across HTTP, gRPC, MCP, and agent-to-agent protocols.
• Centralized oversight: provides security and platform teams with a single view of agent identities, actions, and multi-agent collaboration.
• Reliability features: fallback chains, circuit breakers, and health-aware routing to maintain request flow when providers or services degrade.
• Compliance by design: authenticates, authorizes, classifies, and logs interactions before they happen rather than auditing after the fact.

# Quote "We have long predicted that every company would become API-first, but the rise of agentic AI has turned this into a mandate. If your agents cannot see or securely access your APIs, your business will become irrelevant," said Abhinav Asthana, co-founder and CEO of Postman. He described Fabric Gateway as the control layer that governs discovery, access, and permitted actions for agents.

# How teams might use it Teams that deploy autonomous agents or integrate LLMs with internal tools can use Fabric Gateway to:

• Centralize registration of agent-facing endpoints and MCP servers.
• Apply consistent least-privilege policies across diverse communication protocols.
• Route multi-agent interactions with observability and audit logging.
• Improve resilience of agent-driven workflows through built-in fallback and health routing.

# Where this fits in the market This announcement aligns with other vendor moves releasing agentic or AI-native control planes that add policy-aware orchestration and governance for automated workflows. Postman emphasizes protocol neutrality (including MCP and A2A communications), positioning Fabric Gateway as a bridge between traditional API management and emerging needs for agent governance.

# Practical considerations Fabric Gateway is designed to run inside an organization's cloud to keep control and telemetry local. Organizations adopting it will need to plan for registry consolidation, policy definition across agents and APIs, and integrating gateway logs and identity with existing security and platform tooling.

# Next steps for readers If you manage APIs, platform security, or AI integrations, evaluate whether your current gateway and governance tools cover agent-to-agent and MCP interactions. Where coverage is missing, consider solutions that centralize discovery, enforce least-privilege across protocols, and provide pre-execution authentication and logging.
