## 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**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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 (good).
  - Context-footprint check failed: tool/resource definitions use about 2317 tokens (~210/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability check failed: schema churn in the 14 days we've observed: 11 tool removals, 0 breaking changes, 0 auth/transport breaks, 7 additions.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the Lumi Trades: x402 seller checks and test-buys MCP server?

### 2026-10-22 (score 65)

First indexed and scored.

## MCP tools (11)

### `lumi_trust_check` (~249 tokens)

Lumi: should I pay this x402 URL? (free, rate-limited)

Free (rate-limited per client and per day). Should I pay this x402 URL? Start here before any paid tool. One label (checks_passed / check_first / checks_failed / no_data) plus the allow / warn / block verdict with coded reasons, from Lumi's daily CDP Bazaar index, free 402-quote checks and Lumi's own test-buys (Base USDC for Bazaar listings; XRPL only for a small curated vendor list, counted separately). Pass url, and optionally the payTo and USD amount you were quoted, to catch address or price mismatches. Links the free lookup and, for curated vendors, the paid full report. Observations, not a guarantee. Near the top of the result, paid_option names the paid high-value check (lumi_high_value_check; its price is in its own description), which returns the same verdict and score.

Input parameters:

- `amount` (string): Optional: the quoted price in USD, e.g. 0.01
- `payTo` (string): Optional: the payTo address in its 402 quote
- `url` (string, required): The x402 resource URL you are about to pay

### `lumi_wallet_check` (~190 tokens)

Lumi: which x402 sellers did this wallet pay? (free, rate-limited)

Free (rate-limited, 100 a day). Pass a public wallet address (Base 0x..., XRP Ledger r... or Stellar G...) to list the x402 sellers that wallet paid in the last 90 days, each with the same plain summary line as lumi_trust_check (how many times Lumi test-bought it and how many delivered, or that Lumi has not test-bought it yet) and simple flags (listing looks dead, no longer listed, recent checks failed, repeat or possible duplicate payments). Base reads Lumi's index of public USDC transfers into CDP Bazaar payTos; XRPL and Stellar read the latest 200 ledger entries. Public data only; Lumi does not store the address. No price comparisons. Observations, not a guarantee.

Input parameters:

- `address` (string, required): A public wallet address: Base 0x..., XRP Ledger r... or Stellar G...

### `lumi_catalog` (~53 tokens)

Lumi: endpoints and live prices (free)

Free. Lists Lumi API endpoints, live prices (XRP / RLUSD / USDC on the XRP Ledger, USDC on Base, USDC on Stellar), payment settings of this MCP server and the caller wallet address.

### `lumi_samples` (~89 tokens)

Lumi: free samples of every paid product

Free. A truncated, clearly labelled SAMPLE of each paid product (high_value_check, vendor report) with its USD price and full URL, so you can see the shape and quality before paying. Lists are cut to 2 entries; up to 10 minutes old. Pass route to get one product.

Input parameters:

- `route` (string): Optional product route, e.g. high_value_check or vendor_report

### `lumi_quote` (~130 tokens)

Lumi: price check without paying (free)

Free. Shows the x402 price quote (XRP / RLUSD / USDC on the XRP Ledger, USDC on Base, USDC on Stellar) for any Lumi paid path, e.g. /v1/trust/check/high-value?url=...&amount=10, without paying. A 503 means the data is not fresh right now and the call would not be sold.

Input parameters:

- `path` (string, required): Paid API path, e.g. /v1/trust/check/high-value?url=...&amount=10 or /v1/trust/vendors/printmoneylab/report

### `lumi_vendor_scores` (~299 tokens)

Lumi: x402 vendor observations (free)

Free. Check an x402 seller before you pay it: pass url (the resource you are about to buy), domain, or payTo (the address in its 402 quote, case-insensitive). Lumi ingests the full CDP x402 Bazaar catalog daily and runs free, unpaid 402-quote checks of listings on a rotating schedule (valid quote, price and payTo vs the listing, latency, domain age; live coverage counts in the response), labelled 'quote-checked, low confidence', plus Lumi's own test-buys confirmed on-chain, labelled 'test-bought' and counted per chain (Base USDC buys of Bazaar listings; XRPL buys of a small curated list, separately). Answer-only: the full coded verdict is in the free lumi_trust_check. Observations, not ratings; no match is not a negative finding. With no arguments: the curated XRPL vendor scores and catalog counts; vendor_id gives one curated vendor's summary (tx evidence is in the paid vendor report).

Input parameters:

- `domain` (string): Seller host or domain, e.g. example.com
- `payTo` (string): payTo address from the seller's 402 quote (0x... or r...)
- `url` (string): Resource URL you are about to pay, e.g. https://example.com/api/data
- `vendor_id` (string): Optional curated vendor id, e.g. printmoneylab

### `lumi_verdict` (~230 tokens)

Lumi: one-label pre-payment check (paid)

Paid: $0.01 per call over x402 at GET /v1/verdict (this tool returns the price terms; the free lumi_trust_check and the free signed /v1/check have the same data, so try them first). Before paying an x402 URL or seller domain: one label from the same data and signing key as /v1/check: checks_passed (Delivered in recent checks), check_first (Check first), checks_failed (Recent checks failed) or no_data (Not enough data), with as-of date, evidence window, conclusive test-buy count, last delivered/failed dates, reason codes, evidence and appeal links, and observed on-chain payments as ranges only. Paying Lumi never changes a result. Observations, not a guarantee.

Input parameters:

- `amount` (string): Optional: the quoted price in USD, e.g. 0.01
- `payTo` (string): Optional: the payTo address in its 402 quote
- `url` (string, required): The x402 resource URL (or the seller's domain) you are about to pay

### `lumi_seller_monitoring` (~139 tokens)

Lumi: seller monitoring plans and monitored sellers (free)

Free. Seller monitoring for x402 sellers: Watch and Watch Pro plans per endpoint per 30 days, a one-off audit, test-buy packs, a free Watch tier and a 14-day Watch trial (prices are returned by this tool and in each 402). No auto-renew; payTo proven by signature; paying never changes a score. No args: plans, enrolment steps and safeguards. enrollment_id: that seller's public entry (disclosure, findings, replies) and live badge status. Plans are paid over x402 at the REST URL.

Input parameters:

- `enrollment_id` (string): Optional enrollment id (men_...)

### `lumi_trust_feed` (~70 tokens)

Lumi: trust data feed plans and licence (free)

Free. Licensed trust data feed for facilitators, wallets and frameworks: a free key with a monthly lookup allowance (wallet signature), metered extra lookups, and Feed and Feed Pro plans (snapshot export, webhooks). Returns plans, prices, endpoints and licence terms (no resale, attribution).

### `lumi_high_value_check` (~210 tokens)

Lumi: high value check (paid)

Paid: 0.5% of the stated amount, min $0.005, max $0.25 (e.g. $0.05 for amount=10), per call over x402. Before a larger x402 payment: the same label, allow / warn / block verdict and score as the free lumi_trust_check (paying never changes them), plus a live re-check of the seller at call time and a Lumi-signed receipt bound to the stated amount. Pass url and the USD amount you are about to pay (and optionally the payTo in its quote). The exact price for your amount is in the x402 quote (see lumi_quote).

Input parameters:

- `amount` (string, required): The USD amount you are about to pay, e.g. 10 (sets the price of this check)
- `payTo` (string): Optional: the payTo address in its 402 quote
- `url` (string, required): The x402 resource URL you are about to pay

### `lumi_vendor_report` (~172 tokens)

Lumi: vendor report (paid)

Detailed report on one x402 vendor from Lumi's trust list: full observation history (every free 402-quote check over 90 days, every paid test-buy with tx hash and delivered yes/no), latency stats and 7-day trend, uptime % (24h/7d/30d/90d) and daily series, quoted-price history, agent reports, vendor replies, sample sizes and confidence labels. Automated observations, not a rating. Paid: $0.02 per call over x402 (USDC on Base, XRP / RLUSD / USDC on the XRP Ledger, or USDC on Stellar; the live quote is in lumi_quote). The free summary is lumi_vendor_scores.

Input parameters:

- `vendor_id` (string, required): Vendor id from lumi_vendor_scores, e.g. printmoneylab
