## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 628 tokens (~78/item across 8 items; 8 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (8)

### `search_products` (~82 tokens)

Search products for a buyer intent. Returns ranked candidates with price, availability and product_id.
    Call get_product(product_id) before quoting a specific variant. Prices in major units (USD).

Input parameters:

- `agent` (string)
- `country` (string)
- `limit` (integer)
- `max_price_usd`
- `query` (string, required)

Output parameters:

- `result` (string)

### `get_product` (~46 tokens)

Live details for one product: variants, price, stock status, checkout links.

Input parameters:

- `agent` (string)
- `country` (string)
- `product_id` (string, required)

Output parameters:

- `result` (string)

### `create_checkout` (~81 tokens)

Start a purchase. v0 returns the merchant's checkout link for the chosen variant plus a Kaupia
    checkout_id. Keep the checkout_id and call report_outcome later so the order is covered and ranked.

Input parameters:

- `agent` (string)
- `product_id` (string, required)
- `quantity` (integer)
- `variant_id` (string, required)

Output parameters:

- `result` (string)

### `report_outcome` (~51 tokens)

Report what happened to a checkout: placed | delivered | wrong_item | late | refunded | failed.

Input parameters:

- `checkout_id` (string, required)
- `note` (string)
- `outcome` (string, required)

Output parameters:

- `result` (string)

### `get_quote` (~91 tokens)

Delivered price for one variant to a US zip code: item + the store's own shipping rate for that address +
    estimated sales tax, plus the delivery estimate. Nothing is bought. Use it to compare real totals across stores.

Input parameters:

- `product_id` (string, required)
- `quantity` (integer)
- `state` (string)
- `variant_id` (string, required)
- `zip` (string, required)

### `place_order` (~126 tokens)

Order through Kaupia. customer = {name, email, address1, address2?, city, state, zip, phone?} (US only).
    The user pays Kaupia the delivered price at pay_url (Stripe); Kaupia buys from the store and it ships to the
    user; late, wrong or missing = refund. Confirm item, address and total with the user before calling.

## Common questions

### What is the Kaupia MCP server?

Kaupia is an MCP server listed in the public MCP registry as com.kaupia/kaupia. Where AI agents buy things for people: real US stores, delivered price and date, one order. This page covers its hosted endpoint (https://api.kaupia.com/mcp).

### Is the Kaupia MCP server safe to use?

Kaupia scores 62 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Kaupia MCP server expose?

Kaupia exposes 8 tools: search_products, get_product, create_checkout, report_outcome, get_quote, and 3 more. Their descriptions and schemas cost roughly 538 tokens of context every time the server is loaded.

### Does the Kaupia MCP server require authentication?

No. We connected to Kaupia without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Kaupia MCP server still maintained?

Kaupia is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
