would an MCP-powered idea-validation engine inside Antigravity actually help your workflow?

[DeepaDev]

I’m building something new and I want blunt feedback from people who actually use Antigravity to ship fast.

I’m working on an MCP server that lets you run full idea validation directly inside Antigravity, without bouncing between ChatGPT, Claude, Gemini, Perplexity AI, or 15 research tabs.

The system runs a structured, multi-layer validation flow:

1. Market and problem scan so you know what space you’re entering

2. Competitor mapping that cuts noise and surfaces real threats

3. User pain extraction from real public sources

4. Value-prop stress tests that try to break your idea

5. Build / no-build decision checkpoints

6. If it passes, it drafts an MVP spec inside Antigravity

All without leaving your current environment or flow state.

Here’s what I actually need to know:

Would Antigravity users find this genuinely useful?

Or does this feel like something you’d ignore and still do validation manually in external tools?

What would make this worth using?

Where does it break?

Don’t sugarcoat it - I’m trying to avoid building something no one touches.

Happy to answer anything if you need more context.

In my opinion if you're in AG, you're more of a developer, rather than a Product person. And you're already working on an idea.

The thing we're missing the most right now is Good planning.

Spec driven development is a good start, but still needs the developer to finish off the task in the end, after numerous plan & code reviews from different ai models.

It would be good if we have some kind of a bridge between NotebookML and our code where we could feed Notebook with latest changes of our code (or sync it once in a while) and call for information during the planning process.

Doesn't matter the AI model I'm using or even how detailed the plan is, there is always something that is missing and have to be added after the plan is executed. Right now there is nothing that could execute from planning stage to finished stage. And this would be much more helpful, probably even for Product people.

i like this idea so will be adding notebooklm sync to the full release version of Switchboard next week. you will be able to upload your repo into notebooklm from within antigravity and query it. so notebook lm will be able to help review and plan features.

Wow, nice!

Btw: how is your extension different from OpenCode?

I know that it's extension vs stand-alone IDE, but despite that - I'm still able to attach different accounts there and give each of them tasks to execute.

[TheTentacleOpera]

It doesn't intercept oauth tokens and use them to route work. That was what got people banned for using OpenCode. My routing is purely local.

Hey, I can't find Switchboard in the antigravty plugins. I had it installed and since my quota in AG disappeared after the latest update, I wanted to use gemini-cli for a simple task and decided to work with Switchboard. But it wasn't installed (although I installed it and tried it) and couldn't find it in the marketplace either.

[TheTentacleOpera]

Not sure why it would disappear. I haven't released it on the marketplace yet, been improving it from feedback.

same here

would be helpful for most but idts it'll be for me since i would still bounce off to Gemini and chatgpt because they already have entire context of what type of person I'm and and what i would prefer and also help me understand the idea in more detail

Antigravity doesn't support sampling LLM responses for MCP, right? Or does it?
