- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_timezone (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); validate_iban (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_holidays (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 388 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 388 tokens to load them all
- tool set hash: 553ab4aae2524c51d822d2edf3c81c52
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.freshfos/dropcoin-utility.svg)](https://protogrid.dev/servers/io.github.freshfos/dropcoin-utility)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `get_fx_rate`: ECB reference rates. Omit from/to for the full latest table, or pass from+to (+amount, default 1) to convert. 2 credits, requires an API key.
- `get_holidays`: Public holidays for an EU country and year (2026-2028), optionally narrowed to a German region (e.g. BY). 2 credits, requires an API key.

- `get_vat_rate`: Standard and reduced VAT rates for an EU country (EU TEDB). 1 credit, requires an API key.
- `validate_iban`: Free IBAN check (ISO 13616 check digits + country length), rate-limited per IP, no API key needed. For volume use the paid HTTP endpoint POST /v1/iban/validate (1 credit) — it has no IP limit.
