# Use Eurosys with your agent.

[Eurosys](https://eurosys.pt/) (`eurosys.pt`) registers 5 WebMCP tools. 5 of 5 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on eurosys.pt and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/eurosys.pt) listing for `eurosys.pt`, last live-checked by the registry at 2026-09-22T22:41:06.106Z. Run `ghostget webmcp sites.get --input '{"domain":"eurosys.pt"}' --json` for the current schema; the listing can drift between checks.

## Use Eurosys 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":"eurosys.pt"}' --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":"eurosys.pt","tool":"get_builder_state","input":"{}"}' --json
```

## Registered WebMCP tools

Eurosys publishes 5 tools on eurosys.pt; 5 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `get_builder_state` | Devolve a configuração de PC atualmente montada nesta página: componentes selecionados, preço total com IVA, passo ativo e se há itens sem preço. | Callable read-only tool |
| `list_builder_options` | Lista os componentes disponíveis no PC Builder para um dado tipo (cpu, motherboard, gpu, ram, storage, psu, case, cooler), opcionalmente filtrados por texto. Devolve preço final com IVA e disponibilidade. | Callable read-only tool |
| `list_catalog_categories` | Lista as categorias visíveis do catálogo com o respetivo URL. | Callable read-only tool |
| `recommend_build` | Recomenda uma configuração de PC completa a partir das respostas do questionário (uso, orçamento, marca, estilo de caixa e sub-tipo). Usa a base de configurações pré-geradas; se não houver correspondência devolve { found: false } com a rota | Callable read-only tool |
| `search_catalog` | Pesquisa produtos no catálogo por texto, categoria e intervalo de preço. Devolve os produtos com preço final (com IVA) e o URL canónico de cada um. | Callable read-only tool |

## 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 Eurosys changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on eurosys.pt, browse the site itself or check back when the registry lists more tools.
