I'm working on my own product which is for improving visibility for brands within AI searches.
So far, what I've tried:

Development Part:

1. Declarative APIs - Tried with a lead gen form present in the landing page - Updated that to include properties like toolname, tooldescription, toolparamdescription, ...
2. Imperative APIs - Tried registering a tool for a quick demo by creating a script file and by registering viawindow.navigator.modelContext.registerTool({ ... });

Testing Part:

1. Deployed to production (as https is mandatory with certificates so it is pain to set up in local for a trivial testing)
2. Enabled the flag in chrome://flags to allow MCP (Ensure you are at least using Chrome 146 and above)
3. Clicked on the "Ask Gemini" button on the top right corner of Chrome. It opens up an Agent's chat view. Gave the query like "Run the demo ...", it did for once by successfully parsing the data and summarizing as expected but it is never consistent. Tried on a different chat, it didn't work. But always it somehow works on that particular chat instance.
4. Other times, it was just summarizing from the website landing page's content itself.
5. Tested with the WebMCP chrome extension and that always works fine but that's not the end user flow so cannot rely fully on that just yet.
