# Use SCVD General Store with your agent.

[SCVD General Store](https://scvd.store/) (`scvd.store`) registers 14 WebMCP tools. SCVD General Store lists 14 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/scvd.store) listing for `scvd.store`, last live-checked by the registry at 2026-09-22T21:01:06.398Z. Run `ghostget webmcp sites.get --input '{"domain":"scvd.store"}' --json` for the current schema; the listing can drift between checks.

## Use SCVD General Store 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":"scvd.store"}' --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
```

| `check_conformance` | Verifies any issuer's signed x402 offer or receipt (a compact JWS): structure, the signature against the issuer's did:web key, and liveness.

| `check_order` | Returns the current state of a human-queue order by its order_id: status (queued or completed), the promised window in hours, and the deliverable once completed.

| `look_in_window` | Shows the shop window: the last five trading-card pressings pulled from packs at this store by anybody, every card on show, with the door where one of them can be bought at half a pack. Free. | Listed for discovery; the registry allows read-only calls only |
| `preflight_endpoint` | Is this door's x402 challenge well-formed right now? One unpaid probe returns the verdict, the level reached on the L0–L6 evidence ladder, each check's tri-state result, and what a single probe cannot establish. Shape at one moment: not upt | Listed for discovery; the registry allows read-only calls only |
| `quote_store_purchase` | A free quote for a catalog buy_url or paid publication URL, including query inputs: the x402 v2 terms (offered networks, atomic USDC amounts) and, where the door offers one, the native MPP challenge keyed to the quote's retry key.

Free and unlimited, for artifacts anyone bought or none. | 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 SCVD General Store changes its tools.
- **No account needed.** These calls are credential-free registry reads. For tools that need a session on scvd.store, browse the site itself or check back when the registry lists more tools.
