# Use Chaves Na Mão with your agent.

[Chaves Na Mão](https://chavesnamao.com.br/) (`chavesnamao.com.br`) registers 2 WebMCP tools. 2 of 2 tools declares `readOnlyHint`, so an agent can invoke them through `tools.call`. The registry runs the tool in a fresh headless page on chavesnamao.com.br and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/chavesnamao.com.br) listing for `chavesnamao.com.br`, last live-checked by the registry at 2026-09-21T22:27:23.337Z. Run `ghostget webmcp sites.get --input '{"domain":"chavesnamao.com.br"}' --json` for the current schema; the listing can drift between checks.

## Use Chaves Na Mão 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":"chavesnamao.com.br"}' --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":"chavesnamao.com.br","tool":"search_realty_listings","input":"{}"}' --json
```

## Registered WebMCP tools

Chaves Na Mão publishes 2 tools on chavesnamao.com.br; 2 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `search_realty_listings` | Busca anúncios de imóveis (venda ou aluguel) no Chaves na Mão. Retorna lista paginada com título, preço, localização, quartos, vagas, área e URL. Para buscas 'perto de X', use `proximity.target` para X e não transforme o ponto de referência | Callable read-only tool |
| `search_vehicle_listings` | Busca anúncios de veículos (carros, motos, caminhões, ônibus) no Chaves na Mão. Retorna lista paginada com marca, modelo, ano, KM, preço, localização e URL. IMPORTANTE: use o campo `url` de cada resultado como link do anúncio — não reconstr | 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 Chaves Na Mão changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on chavesnamao.com.br, browse the site itself or check back when the registry lists more tools.
