MCP

Three people have asked for this in the past week, each wanting something slightly different, and the differences matter.

One wants to generate a large number of extensions from written specifications rather than by typing into the builder two hundred times.

One wants an agent to create a project and push a planned sequence of prompts into it, then hand back the result.

And one is not a developer at all. He is copying prompts and errors back and forth between ChatGPT and PlugThis by hand, and wants the two to talk to each other so an extension can be built, tested, fixed and retested without him carrying the error across each time.

That last one is the most interesting, because it is not really about automation. It is about not being the messenger.

WHAT THIS WOULD BE

An API you can call from your own scripts, or from an agent, to do what you do in the builder today. Create a project. Send a prompt. Get the result back. See whether it built and why it failed if it did not.

MCP would sit on top of that rather than beside it. It is a thin layer that lets Claude or ChatGPT use the API as a tool, so the API has to exist first either way. That simplifies the decision: build the API, and MCP comes almost free afterwards.

THE ONE THING THAT WOULD MAKE IT SAFE

If a build is going to run without somebody watching it, the result has to be checkable without a person.

So the response should say what was actually produced. The files, the final manifest read back out of the finished package, and whether it matches what was asked for. A build that quietly produces something broader than requested should fail rather than deliver.

That is worth more than the automation itself. It is the difference between generating at volume and generating at volume safely.

WHAT IS NOT DECIDED

Whether a sequence runs unattended, or each build comes back so you choose the next prompt. Those are different products and I do not yet know which people want.

If you vote for this, say which of the three shapes above is yours. That is the part that will decide what gets built. Please leave comments.
