## 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 2026-10-18.

- **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 406, 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**: 76/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 391 tokens (~97/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
  - 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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.

## MCP tools (4)

### `catalog` (~27 tokens)

Catalog: tools, prices and limits

List the tools of this server with prices, data sources, licensing, daily limits and data freshness.

Output parameters:

- `daily_limits` (object): Daily limits of paid calls (calls, usd, timezone) or a misconfiguration notice.
- `fetch_status_values` (object)
- `legal` (object)
- `paused` (object): Operator pause flags (true = paused).
- `payment` (object)
- `provenance` (array): Freshness receipts for every upstream source used.
- `server` (object)
- `terms` (string): URL of the terms of service.
- `tools` (array): Every tool of this server with its price.

### `x402_parse_payment_request` (~207 tokens)

Parse an x402 payment request

Free. Decode one x402 v2 payment request (base64 PAYMENT-REQUIRED header, PaymentRequired JSON or MCP tool result) and list every accepts option with exact atomic and decimal amounts. Token addresses are compared with a limited reference list. status: parsed, ambiguous (options differ in recipient, network or amount; none is chosen), malformed or unsupported. Does not verify the merchant, authorize a transfer, assess fraud risk, or guarantee any payment. URLs in the input are never fetched.

Input parameters:

- `raw` (required): The payment request. A string: the base64 PAYMENT-REQUIRED header value (a leading 'PAYMENT-REQUIRED:' is allowed) or JSON text. An object: the PaymentRequired JSON, or for transport mcp the tool res…
- `transport` (string): Where the request came from: http (402 response) or mcp (paid tool result). Default http.

Output parameters:

- `checked_scope` (object)
- `comparisons` (array)
- `decoded_from` (string|null)
- `errors` (array)
- `evidence` (array)
- `mismatches` (array)
- `mode` (string)
- `note` (string)
- `parsed`: The decoded request with every accepts option (null unless status is parsed or ambiguous).
- `payment_required_location`
- `provenance` (object): Version and sources of the bundled asset table.
- `status` (string): parsed = the checked x402 v2 structure had no defects (not a statement about the merchant or whether to pay). ambiguous = options differ in recipient, network or amount; none was chosen. malformed /…
- `terms` (string): URL of the terms of service.
- `unsupported` (array)
- `warnings` (array)

### `x402_known_assets` (~74 tokens)

x402 known assets and networks table

Free. The limited reference list this server compares token addresses with: known assets (network, contract, symbol, decimals) with sources and check dates, known CAIP-2 networks, scheme names from the x402 specs, and payment flows. A table match is not proof that an asset or a merchant is genuine.

Output parameters:

- `assets` (array): Known assets per CAIP-2 network.
- `networks` (object)
- `payment_flows` (object)
- `provenance` (object): Version and sources of the bundled asset table.

- `terms` (string): URL of the terms of service.

### `get_receipt` (~83 tokens)
