velora-mcp-demo

Free, always-on public demo of the Velora agentic-commerce MCP toolkit — hosted on Vercel's free Hobby plan, $0/month, no card, no billing cycle.

Serves tools.somosvelora.com — the production Cloud Run backend that used to live there is paused on purpose (cost), so this demo replaces the old 404 with something real: a live MCP server, Streamable HTTP transport, real tool schemas, and an explicit honesty design instead of a dead link.

Endpoints

• /api/mcp — full tool surface (~49 tools, mirrored from the real production tool set).

• /api/mcp/public — read-only subset with zero side effects (matches the URL already printed in the latam-tools repo).

Three honesty levels (see lib/shared/types.ts and lib/shared/register.ts)

1. Pure — validate_cuit runs the real Argentine AFIP/ARCA check-digit algorithm for real, against whatever CUIT/CUIL you send it. No fixture involved.

2. Read — tools that only look something up (catalog, customers, caja balance, sales metrics, shipping quotes, connection status, the open_* MCP Apps widgets, …) return a fixed, fictional dataset ("Almacén Demo SRL"). Every response carries a [DEMO] Datos de muestra — el backend de producción está pausado. banner and _demo: true in its JSON body — never mistakable for a real business.

3. Refuse — tools with a real side effect in production (emit_invoice, emit_nota, register_sale, create_tracked_payment_link, send_whatsapp_text, caja_ciclo_caja, connect_mercadopago, …) return isError: true with an honest explanation. No fabricated CAE, payment id, tracking number, or credential — ever. The tool's name, description, and input schema are still the real production ones; only the execution is disabled.

Where the tool names/schemas came from

Every tool name, description, and Zod input shape here is copied/trimmed from the currently-registered tools in the private velora-track3-repo production codebase (src/lib/mcp/*.ts), verified file-by-file — not invented. One known gap, found while building this: the developer-facing /developers catalog page in that repo lists ~60 tool names (CUIT/CUIL/CBU validators, format_ars, split_iva, to_afip_date, build_afip_qr, describe_invoice_type, consultar_comprobante, consultar_padron) that are not actually registered as MCP tools anywhere in the codebase — they exist only on the marketing page. This demo mirrors the ~49 tools that are actually real and registered, not the marketing count.

Demo endpoint — sample data only. The real Velora product lives at somosvelora.com; this repo is a portfolio/demo piece, not the production system.
