## 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 2026-09-20.

- **Endpoint Security**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 86/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1376 tokens (~114/item across 12 items; 10 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 97/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 90% 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 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 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 (10)

### `rates_latest` (~138 tokens)

Latest ECB reference rates

Call this tool for the latest ECB daily reference rates against any base: 1.0812 for USD means 1 base = 1.0812 USD. Crosses go through the euro. Returns the ECB rate date and the cache age.

Input parameters:

- `base` (string): Base currency; defaults to the shared business profile's default_currency, else EUR. A rate of 1.0812 for USD means 1 base = 1.0812 USD. Cross rates go through the euro, the only pair the ECB publish…
- `quotes` (array): Only these currencies, at most 200. Omit for all of them

### `convert` (~244 tokens)

Convert an amount

Call this tool to convert an amount between any two ECB-quoted currencies, today or on a past date. Returns the converted amount, the cross rate to 6 decimals, the rounding applied and the rate date used.

Input parameters:

- `amount` (number, required): Amount in major units of the from currency, e.g. 100 or 12.34
- `date` (string): ISO date YYYY-MM-DD. Omit for the latest published rate. A weekend or TARGET holiday falls back to the last rate published on or before it, and the answer says so. A date older than the free 90-day w…
- `from` (string, required): Currency the amount is in. Cross rates go through the euro, the only pair the ECB publishes
- `to` (string): Currency to convert into; defaults to the shared business profile's default_currency, so you are never asked what currency you invoice in. The result is rounded once, at the end, to this currency's o…

### `convert_many` (~86 tokens)

Convert one amount into several currencies

Convert one amount into many currencies off the SAME ECB rate date, each rounded to its own minor units. For several lines at once (mixed-currency invoice lines), call it once per line: every line then shares one rate date. Unknown targets are listed, never failed.

Input parameters:

- `amount` (number, required)
- `from` (string, required)
- `to` (array, required): Target currencies

### `fx_rates_for` (~160 tokens)

FX rates in the shape expense-tracker wants

Call this tool when a rebill or an invoice spans more than one currency, instead of asking the user for rates. Returns the fx_rates object expense_to_invoice takes, plus the rate date to write on the invoice.

Input parameters:

- `currencies` (array, required): The other currencies present, e.g. ["EUR", "GBP"]. Direction: each returned rate means 1 unit of that key = X units of the target, so {"EUR": 1.08} is 1 EUR = 1.08 of the target. The target needs no…
- `target` (string): The currency the invoice will be issued in; defaults to the shared business profile's default_currency. Pass it on as target_currency alongside the fx_rates object

### `rate_history` (~213 tokens)

Rate history for a pair

Call this tool for the ECB rate of one currency pair across a window. Returns one row per published day plus the min, max, average and the change. A window wider than the free 90 days is shortened, not refused.

Input parameters:

- `days` (integer): Trailing window in calendar days, default 30. Only TARGET business days carry a rate, so 30 days holds about 21 rows. Free reads up to 90 days back; Pro reads the whole series back to 1999-01-04
- `from` (string, required): Base currency of the pair
- `from_date` (string): ISO date, inclusive. Overrides days. Free is limited to the last 90 days
- `max_rows` (integer): Cap the table, default 200. min/max/avg still cover the whole window
- `to` (string, required): Quote currency of the pair. Each row is 1 from = X to
- `to_date` (string): ISO date, inclusive, default today

### `rate_on` (~231 tokens)

Rate on a given date

Call this tool for the ECB rate of one pair on one date. Returns both directions and the rate date, so a reciprocal is never reported as the published figure. A date beyond the free window is shortened, never refused.

Input parameters:

- `date` (string, required): ISO date YYYY-MM-DD. If the ECB published nothing that day - every weekend, 1 January, Good Friday, Easter Monday, 1 May, 25 and 26 December - the last rate published on or before it is returned and…
- `from` (string, required): Base currency. The ECB quotes every currency per 1 euro, so "the ECB rate for USD" is from EUR to USD, not the other way round; invert only if the user asked for the inverse
- `to` (string, required): Quote currency. The rate returned is 1 from = X to

### `currencies_list` (~48 tokens)

Currencies the ECB quotes

Every currency in the ECB daily set with its rate against the euro and its decimal places. This is the whole domain: a code not on this list cannot be converted, quoted or historised here.

### `cache_status` (~54 tokens)

Rate cache status

Report the ECB rate cache here: which dates are held, how old they are and when they refresh. Reads only. Check it before trusting a rate after time offline; a cache that no longer parses is quarantined and named.

### `license_status` (~55 tokens)

License status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

### `license_activate` (~76 tokens)

Activate license

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

Input parameters:

- `key` (string, required): License key from checkout, MCPL1.<payload>.<signature>
