Yeah, I don't think I was particularly clear in that section.
I don't think MCP is going to go away, but I do think it's unlikely to ever achieve the level of excitement it had in early 2025 again.
If you're not building inside a code execution environment it's a very good option for plugging tools into LLMs, especially across different systems that support the same standard.
But code execution environments are so much more powerful and flexible!
I expect that once we come up with a robust, inexpensive way to run a little Bash environment - I'm still hoping WebAssembly gets us there - there will be much less reason to use MCP even outside of coding agent setups.
I disagree. MCP will remain the best way to do most things for the same reason REST APIs are the main way to access non local services: they provide a way to secure and audit access to systems in a way that a coding environment cannot. And you can authorize actions depending on the well defined inputs and outputs. You can’t do that using just a bash script unless said script actually does SSO and calls REST APIs but then you just have a worse MCP client without any interoperability.
I find it very hard to pick winners and losers in this environment where everything changes so quickly. Right now a lot of people are using bash as a glue environment for agents, even if they are not for developers.
