# Use Madrid Day Spa by Nuilea with your agent.

[Madrid Day Spa by Nuilea](https://madrid-day-spa.com/) (`madrid-day-spa.com`) registers 5 WebMCP tools. 4 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 madrid-day-spa.com and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/madrid-day-spa.com) listing for `madrid-day-spa.com`, last live-checked by the registry at 2026-09-22T22:12:20.415Z. Run `ghostget webmcp sites.get --input '{"domain":"madrid-day-spa.com"}' --json` for the current schema; the listing can drift between checks.

## Use Madrid Day Spa by Nuilea 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":"madrid-day-spa.com"}' --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":"madrid-day-spa.com","tool":"get_availability","input":"{}"}' --json
```

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |

| `get_digest` | Read detailed information about the spa: what a treatment category involves, the FAQ (location, parking, payment and booking policy, what to bring, cancellations), how gift cards work, and review summaries. Use this before answering anythin | Callable read-only tool |
| `get_gift_details` | Look up a gift voucher by the 5-character CODE printed on it (letters and numbers, for example K7M2X): whether it is valid, until when, and what it can be spent on. It does NOT accept the voucher number — a voucher that only has a number is | Callable read-only tool |
| `get_services` | List the spa treatments with their duration and price. Optionally filter by a word in the name, for example "hammam", "facial" or "massage". Use this to find a treatment id before calling other tools. | Callable read-only tool |
| `navigate_to` | Take the user to a treatment's page on this site, optionally opened on a specific date and for one or two people. Use after the customer has settled on a treatment. Omit treatmentId to go to the general booking 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 Madrid Day Spa by Nuilea changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on madrid-day-spa.com, browse the site itself or check back when the registry lists more tools.
