Congratulations @prathmesh_patel and the MCPJam team! The Descope team can speak from first-hand experience how helpful MCPJam has been as a debugging tool while we worked to support Cross-App Access (XAA) in our platform.
Question for you: what role do you see MCP (and by extension MCPJam) playing in agentic commerce over the coming years?
MCPJam
@abhishekiyer52 great Q Abhishek and thank you! Users are staying in these AI applications- and spending less time in other webapps/mobile apps. We're already seeing a critical mass of ecommerce plugins in the ChatGPT/Claude marketplaces, and these are backed by MCP and plugins by extension. We have ACP support + MCP apps support, those two are being tested by a number of devs on our platform right now. Looking forward to seeing where it goes!
Love, love, love. Most people aren't thinking broadly enough about MCPs. They are products in and of themselves at this point and need to be treated as such.
@zack_drew_evermuse Exactly! Users aren't just reaching products through apps anymore, they're coming in through ChatGPT, Claude and other AI clients. That means MCP servers need to be treated and tested like products :)

Congrats on this launch! This is my go-to MCP inspector! configuring the capabilities like the actual clients saves soooo much time when testing!
MCPJam
@torresmateo Awesome to hear- looking forward to keeping up with those clients!
I use MCPJam daily and it's my goto for testing MCP Servers, MCP Apps and teaching others how to do it.
