A page an agent can operate, not just read.
This page registers WebMCP tools with your browser, so an assistant can query US environmental-risk data for all 42,679 ZIP codes by calling functions here instead of scraping the screen - and can write to the shortlist below, where you watch it happen. The same federal records are published as free, human-readable reports at ZipCheckup.
Every value carries its source, its snapshot date and the legal threshold it is judged
against. Values missing from the source come back as an explicit unknown with a
reason, never as a reassuring zero. On drinking-water data that distinction is the product.
Shortlist
Shared state. You and the agent write to the same list.
- Nothing shortlisted yet.
Registered tools
Read back from getTools(), not from our own list.
Agent console
For anyone without an agent attached: call any registered tool by hand and read the exact payload an agent receives.
Raw payload the agent receives
Run a tool to see the payload an agent receives.
Letter draft
Built only from values the source actually has. Anything unknown becomes a question, never an allegation.
No draft yet.
Activity
Every tool call, who made it, and how much of the answer was actually known.
