Postman 12.7.1
Postman App introduces MCP server support in Flows, letting AI Agent blocks use deployed Flows as tools and enabling MCP Trigger blocks to create deployable Flows for reuse across AI apps.
What’s New
Connect Flows deployed as MCP Servers
The AI Agent Block now supports MCP servers as tools, meaning you can connect any Flow deployed as an MCP server and let the agent call it during execution. This brings composable, reusable logic into your AI workflows: instead of rebuilding capabilities inside a single Flow, you can expose them as MCP servers and let the agent decide when and how to use them.
To learn more, see The AI Agent block.
MCP Trigger Block
Postman Flows now supports MCP (Model Context Protocol) as a trigger type. Create and deploy Flows as MCP servers to use them as tools in other AI applications and Flows. Generate tool definitions with AI or define custom schemas manually.
To learn more, see Create a deployable flow with an MCP block.

Postman CLI v1.33.6
Postman CLI adds CLI generation from Postman collections or OpenAPI specs and expands Flows with a --scenario option for triggering named scenarios. The update is aimed at both agents and humans, with new ways to build and run command-line workflows.
What’s New
Generate CLIs from your Postman Collection or API specification
Available on Team and Enterprise plans
You can now generate a fully-functioning command-line interface (CLI) application based on your Postman collections or OpenAPI specifications. The Postman CLI has been enhanced with two main end-users in mind: Agents (LLMs) and humans.
To learn more, see Generate CLI from your collection or specification.
Specify input data for Postman Flows
You can now use the
--scenariooption with thepostman flows triggercommand to specify a named scenario from the flow definition to construct the input payload, headers, and query parameters.To learn more, see Flows commands.

Postman 12.5.5
Postman App adds clearer performance test insights with a Tests vs VU view and heatmap that shows how assertion failures change as load increases. It also improves Postman Flows with file watcher sync in Native Git mode and folder support for cleaner local organization.
What’s New
Visualize test assertion failures under load
Postman now supports the Tests vs VU view in performance test results, giving you a clear view of how your test assertions behave as load increases. This view includes a heatmap that highlights failure rates across virtual user levels, helping you quickly identify when and where your business logic starts to break under load.
To learn more, see View test assertions by virtual user load in performance tests.
Improvements
File watcher support in Postman Flows
When working in Native Git mode in Postman Flows, local file changes now automatically sync to the Postman app. This works whether you're editing in your IDE, terminal, or file explorer.
Folder support in Postman Flows
Create and organize Flows in folders locally. Folder structures automatically mirror in the app, and push/pull operations maintain your organization without dependency conflicts or rename issues.
