Assuming the latter, are there any viable non-developer MCP clients?

I think the agentic use cases aside, the client side of MCPs are still lacking quite a bit and would need to mature to be able to catch up to the spec. I feel a lot of use cases exist outside of fully automated agentic approaches, since we can't really rely on LLMs yet to produce at a human level.

The underserved cases rely a lot on prompt and resource management at the moment. Being able to iterate and share those across teams to provide easy starting points to delegate tasks is something I feel would be workable for the current iteration of AI assisted work, outside of pure software engineering.

Hopefully other clients join VS Code Copilot to allow more varied approaches than just simple tool calls here. I think Copilot's approach on prompt and resource management isn't quite the best approach either though. It is still early days for MCPs in general so i think we'll see a lot of experiments in this space.

The idea is each plugin runs in their own wasm vm with limited network/file system access. Plugins are written in any language, as long as they can compile to WASM and publish to OCI registry (signed & verified with sigstore)

Recently, Microsoft released their own version of hyper-mcp named Wassete[2]

Ideally, I want to make it like a gateway with more security & governance features in this layer.
