WebMCP Registry site · v0.18.35
Use Kontakt & Kundeservice with your agent.
Kontakt & Kundeservice (demo.cartwright.app) registers 8 WebMCP tools. 3 of 8 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on demo.cartwright.app and returns untrusted site content.
This page mirrors the WebMCP Registry listing for demo.cartwright.app, last live-checked by the registry at 2026-09-23T04:53:29.140Z. Run ghostget webmcp sites.get --input '{"domain":"demo.cartwright.app"}' --json for the current schema; the listing can drift between checks.

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 --json
Read the live tool schema — every registered tool, its input schema, annotations, and the page that publishes it:
ghostget webmcp sites.get --input '{"domain":"demo.cartwright.app"}' --json
Call 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":"demo.cartwright.app","tool":"calculate_brew_ratio","input":"{}"}' --json

| Tool | What it does | Callable through Ghostget |
|---|---|---|
add_current_product_to_cart | Add "Ethiopia Yirgacheffe" (149,00 kr.) — the product on this page — to the shopping cart. Specifications: origin: Ethiopia; process: Washed; roast: 2; weightG: 250. Reversible — the user can remove it from the cart page. Returns the update | Listed for discovery; the registry allows read-only calls only |
calculate_brew_ratio | Calculate this roastery's recommended pour-over recipe from its own brewing guide: cups of coffee → grams of ground coffee and grams of water. Pure, instant calculation. | Callable read-only tool |
contact_store | Send a message to this store's support. The message is triaged by AI first (instant answer when possible) and otherwise forwarded to a human. High-impact communication — asks the user to confirm before submitting. | Listed for discovery; the registry allows read-only calls only |
get_cart | Read the current shopping cart: line items with ids (usable with the cart page's update and remove tools — navigate to '/da/cart' to use them), quantities, per-line and total prices with currency, and stock ceilings. | Callable read-only tool |
navigate | Navigate the browser to an internal page on this store, e.g. '/da/produkter', '/da/produkter?q=oak', or '/da/product/<slug>'. Accepts same-origin paths beginning with '/'. | Listed for discovery; the registry allows read-only calls only |
newsletter_signup | Subscribe an email address to this store's marketing newsletter — an opt-in to promotional email. Nothing is sent until the user submits the form themselves; the call completes when they do. | Listed for discovery; the registry allows read-only calls only |
search_products | Search this store's product catalogue by free text and return matching products (id, title, minor-unit price, formatted price, currency, url, stock). Returns results directly without changing the page. | Callable read-only tool |
site_search | Open this store's search results page so the user can see matching products. This navigates the browser; to read product data without leaving the page, use search_products instead. | Listed for discovery; the registry allows read-only calls only |
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 Kontakt & Kundeservice changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on demo.cartwright.app, browse the site itself or check back when the registry lists more tools.
