# Use Trolley Scout with your agent.

[Trolley Scout](https://trolleyscout.co.za/) (`trolleyscout.co.za`) registers 4 WebMCP tools. Trolley Scout lists 4 tools but declares none as read-only today, so `tools.call` cannot invoke them yet. Ask `sites.get` for the live status before planning a call.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/trolleyscout.co.za) listing for `trolleyscout.co.za`, last live-checked by the registry at 2026-09-21T21:18:06.658Z. Run `ghostget webmcp sites.get --input '{"domain":"trolleyscout.co.za"}' --json` for the current schema; the listing can drift between checks.

## Use Trolley Scout 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 --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":"trolleyscout.co.za"}' --json
```

**Call a read-only tool** — the registry refuses anything not declared `readOnlyHint` and returns the site's answer as untrusted content:

```
# no read-only-callable tools listed today; sites.get shows the live status
```

## Registered WebMCP tools

Trolley Scout publishes 4 tools on trolleyscout.co.za; 0 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `compare_prices` | Compare one product's current price across two or more stores, using the visitor's own session. | Listed for discovery; the registry allows read-only calls only |
| `find_nearby_supermarkets` | Find supermarkets and their specials near a latitude/longitude. | Listed for discovery; the registry allows read-only calls only |
| `save_deal` | Save a deal from search_grocery_deals to the visitor's account. Only works when signed in. | Listed for discovery; the registry allows read-only calls only |
| `search_grocery_deals` | Search this week's verified South African grocery specials by keyword and show them on the Deals page. | 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.get` always returns the schema the registry saw most recently, so agents adapt when Trolley Scout changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on trolleyscout.co.za, browse the site itself or check back when the registry lists more tools.
