I've found it to be amazing purely as a new form factor for software delivery. There's a middle ground so common in enterprise where there's a definite need for some kind of custom solution to something, but not enough scale or resourcing to justify building out a whole front end UI, setting up servers, domains, deploying, and maintaining it. Now you can just write a little MCP tool that does exactly what the non-technical end user needs and deliver it as a locally installed "plugin" to whatever agentic tooling they are using already (Claude Desktop, etc). And using Smithery, you don't even have to worry about the old updating concerns of desktop software either; users get the latest version of your tooling every time they start their host application.
