# Use NYC RSVPs with your agent.

[NYC RSVPs](https://nycrsvps.com/) (`nycrsvps.com`) 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 nycrsvps.com and returns untrusted site content.

This page mirrors the [WebMCP Registry](https://wmcp.ai/sites/nycrsvps.com) listing for `nycrsvps.com`, last live-checked by the registry at 2026-09-23T01:41:21.695Z. Run `ghostget webmcp sites.get --input '{"domain":"nycrsvps.com"}' --json` for the current schema; the listing can drift between checks.

## Use NYC RSVPs 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":"nycrsvps.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":"nycrsvps.com","tool":"find_restaurants","input":"{}"}' --json
```

## Registered WebMCP tools

NYC RSVPs publishes 2 tools on nycrsvps.com; 2 declare `readOnlyHint`.

| Tool | What it does | Callable through Ghostget |
| --- | --- | --- |
| `find_restaurants` | Search and filter NYC restaurants tracked by this site. Use this tool when the user wants to find restaurants, browse dining options, or look up reservation details for a specific restaurant. All filter parameters are optional and case-ins | Callable read-only tool |
| `get_reservation_open_date` | Calculate exactly when reservations open for a specific restaurant on a desired date. Use this tool when the user wants to know when to book, when reservations drop, or when to set a reminder for a specific dining date. Returns one of two | 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 NYC RSVPs changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on nycrsvps.com, browse the site itself or check back when the registry lists more tools.
