Security Report
Well-structured MCP server with proper authentication scoping and clean code quality. The read tools require no authentication and call a public API, while the sensitive create_order operation is properly gated behind a shared HMAC secret (GCS_INTERNAL_SECRET). Input validation via Zod is present, error handling is appropriate, and there are no malicious patterns or dangerous operations detected. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

@giftcardshop/mcp
MCP server that lets AI agents browse the giftcardshop catalog and buy gift cards with Lightning - no account, no signup. The agent pays a Lightning invoice and receives a single-view reveal link with the code.
Read tools work against the live public API with no key. create_order is
early access: it needs the shared GCS_INTERNAL_SECRET (request one at
https://giftcardshop.org/contact); without it the read tools still work and
create_order reports that it is not configured.
Tools
| Tool | Kind | Backed by |
|---|---|---|
list_brands | read | GET /v1/brands |
search_products | read | GET /v1/products |
get_product | read | GET /v1/products/:id (variants + denominations) |
get_order_status | read | GET /v1/orders/:id (payment state + reveal availability) |
create_order | write | POST /internal/agent-orders (HMAC) -> Lightning invoice |
Read tools pass the API JSON through verbatim. create_order returns
{ orderId, invoiceId, invoiceUrl, bolt11?, sats?, total, currency, expiresAt }.
Run
# read-only (browsing works, create_order reports "not configured")
npx @giftcardshop/mcp
# with checkout enabled
GCS_INTERNAL_SECRET=<64-hex> npx @giftcardshop/mcp
Claude Desktop / any MCP client (stdio):
{
"mcpServers": {
"giftcardshop": {
"command": "npx",
"args": ["-y", "@giftcardshop/mcp"],
"env": { "GCS_INTERNAL_SECRET": "<64-hex>" }
}
}
}
Config
| Env | Default | Purpose |
|---|---|---|
GCS_API_BASE | https://api.giftcardshop.org | public API base |
GCS_INTERNAL_SECRET | (unset) | 64-hex HMAC secret; enables create_order. Unset = read-only. |
Checkout (create_order)
create_order POSTs to POST /internal/agent-orders, HMAC-signed with
GCS_INTERNAL_SECRET (header x-internal-sig), and returns a Lightning
invoice. Pay it, then poll get_order_status for the single-view reveal
link. No Nostr identity and no partner account required.
Roadmap
- L402 (Lightning HTTP 402) so an agent pays per-call without a human step.
- A hosted remote MCP over HTTP, so there is nothing to install.
- A btcrecharge MCP for mobile top-ups (same shape).
