## 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 2026-09-28.

- **Endpoint Security**: 69/100
  - 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.
  - 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**: 82/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 598 tokens (~99/item across 6 items; 6 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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 (6)

### `catalog` (~79 tokens)

Get the scope, allowed tool names, source IDs, endpoint and access policy for this thematic MCP. Call with no arguments when setting up this connection; skip it when the desired data tool and inputs are known. Use the listed domain directories only to resolve missing identifiers or coverage. This static catalog does not guarantee current availability; inspect the data response status and freshness.

Output parameters:

- `available_records` (integer)
- `capabilities` (array)
- `independently_verified` (boolean): Official-source checks are not independent factual corroboration.
- `name` (string)
- `profile` (string)
- `title` (string)
- `tools` (array)
- `version` (string)

### `get_exchange_rates` (~70 tokens)

ECB indicative daily currency reference rates against EUR. Not real-time or executable prices; inspect observation_date. Original rates freely available at the cited ECB source.

Input parameters:

- `currency` (string): Optional uppercase currency code, for example USD; omit for all available ECB reference currencies. Values are currency units per one EUR.

Output parameters:

- `available_currencies` (array)
- `directory` (string)
- `independently_verified` (boolean): Official-source checks are not independent factual corroboration.
- `items` (array)
- `notice` (string)
- `returned` (integer): Domain-specific result count, not necessarily the number of stored records in items.
- `selected_rate`
- `status` (string): Read this before using values; a successful transport does not establish data availability.

### `list_exchange_rate_history` (~47 tokens)

List available currencies, annual snapshots since 1999 and explicit gaps in ECB daily reference FX history. Some currencies have been discontinued. Units per EUR; original data freely available at ECB.

Output parameters:

- `base_currency` (string)
- `currencies` (array)
- `endpoint` (string)
- `frequency` (string)
- `independently_verified` (boolean): Official-source checks are not independent factual corroboration.
- `missing_or_expired_years` (array)
- `numeric_values` (integer)
- `original_data_free` (boolean)
- `query` (string)
- `refresh` (string)
- `source` (string)
- `years` (array)

### `get_exchange_rate_history` (~168 tokens)

ECB historical daily reference rates for one currency against EUR. Provide year (1999 onward) or an exact date, not both. Default: current year. Returns one year at most, original decimals, missing values and evidence. No weekend carry-forward, interpolation, current quote for discontinued currencies, cross rates or executable prices.

Input parameters:

- `currency` (string, required): Uppercase non-EUR currency code from list_exchange_rate_history, for example USD. Values are currency units per one EUR.
- `date` (string): Exact source date YYYY-MM-DD, for example 2008-09-15; cannot be combined with year. No filling of weekends or gaps.
- `year` (integer): One source calendar year since 1999; defaults to the current year. Cannot be combined with date.

Output parameters:

- `currency` (string)
- `directory` (string)
- `independently_verified` (boolean): Official-source checks are not independent factual corroboration.
- `interpretation` (object)
- `items` (array)
- `notice` (string)
- `requested_date` (string|null)
- `returned` (integer): Domain-specific result count, not necessarily the number of stored records in items.
- `status` (string): Read this before using values; a successful transport does not establish data availability.
- `year` (integer)

### `get_record` (~60 tokens)

Get an unexpired record with provenance and its explicit verification level. Source/schema validation is not independent factual verification.

Input parameters:

- `id` (string, required): Opaque record id returned by a DatoQA data response. Reuse it exactly; do not invent an id.

Output parameters:

- `citation` (object)
- `data` (object): Source-specific payload; inspect units, observation dates, nulls and source notes.

- `freshness` (object)
- `id` (string)

### `get_evidence` (~61 tokens)

Retrieve the source JSON snapshot and SHA-256 digest for a currently available record. The digest proves snapshot integrity, not factual truth.

Input parameters:

- `id` (string, required): Record id returned by a DatoQA data response; returns the retained source snapshot for that record.

Output parameters:

- `first_observed_at` (string)
- `hash_scope` (string)
- `notice` (string)
- `record_id` (string)
- `sha256` (string)
