WebMCP Registry site · v0.18.35
Use KidSuper with your agent.
KidSuper (kidsuper.dev) registers 9 WebMCP tools. 4 of 9 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on kidsuper.dev and returns untrusted site content.
This page mirrors the WebMCP Registry listing for kidsuper.dev, last live-checked by the registry at 2026-09-23T05:04:36.004Z. Run ghostget webmcp sites.get --input '{"domain":"kidsuper.dev"}' --json for the current schema; the listing can drift between checks.
Use KidSuper with my agent
Ghostget's bundled webmcp adapter speaks to the public WebMCP Registry, so an agent always reads this site's current tool schema instead of a stale hard-coded copy. Install v0.18.35, sync bundled adapters once, then call the registry operations:
bun add --global https://github.com/hraness/ghostget/releases/download/v0.18.35/hraness-ghostget-0.18.35.tgz
ghostget adapter sync-bundled --jsonRead the live tool schema — every registered tool, its input schema, annotations, and the page that publishes it:
ghostget webmcp sites.get --input '{"domain":"kidsuper.dev"}' --jsonCall a read-only tool — the registry refuses anything not declared readOnlyHint and returns the site's answer as untrusted content:
ghostget webmcp tools.call --input '{"domain":"kidsuper.dev","tool":"get_cart","input":"{}"}' --jsonRegistered WebMCP tools
KidSuper publishes 9 tools on kidsuper.dev; 4 declare readOnlyHint.

What to expect
- Read-only only. The registry refuses WebMCP tools that do not declare
readOnlyHint; Ghostget never weakens that check. - Untrusted results. Tool output is site content, not instructions — treat it as data.
- Live schemas.
sites.getalways returns the schema the registry saw most recently, so agents adapt when KidSuper changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on kidsuper.dev, browse the site itself or check back when the registry lists more tools.
