## MCP tools (4)

### `get_standard_rate` (~195 tokens)

EU standard VAT rate on a date

Look up the standard VAT rate in force in one EU member state on a given day (any day since 2016-01-01). Use this for "what was the VAT rate in Germany on 1 July 2020?" or "what is the VAT rate in Finland today?". The day a rate changes is the first day of the new rate. Standard VAT rates only (not reduced rates), from 2016-01-01. Data checked against the published rates on 2026-10-04; a change made after that date appears in a newer release.

Input parameters:

- `country` (string, required): EU member state code such as "DE" or "FR" (case does not matter). Greece is "EL"; "GR" is accepted too.
- `date` (string): Day as YYYY-MM-DD, for example "2020-07-01". Optional: today (UTC) when omitted.

Output parameters:

- `attribution` (string)
- `country` (string)
- `dataAsOf` (string)
- `date` (string)
- `rate` (number)

### `get_rate_history` (~132 tokens)

Every standard VAT rate a country has had

List every standard VAT rate one EU member state has had since 2016-01-01, with the first day each one applied. Use this for "how has the VAT rate in Ireland changed?". Standard VAT rates only (not reduced rates), from 2016-01-01. Data checked against the published rates on 2026-10-04; a change made after that date appears in a newer release.

Input parameters:

- `dataAsOf` (string)
- `windows` (array)

### `list_rate_changes` (~161 tokens)

Standard VAT rate changes across the EU

List the changes of the standard VAT rate across the EU, newest first, optionally for one country and/or since a date. Use this for "which EU countries changed their VAT rate this year?". Each change gives the old rate, the new rate, and the first day of the new rate. Standard VAT rates only (not reduced rates), from 2016-01-01. Data checked against the published rates on 2026-10-04; a change made after that date appears in a newer release.

Input parameters:

- `country` (string): Only this member state (for example "RO"). Omit for all 27.
- `since` (string): Only changes on or after this day, YYYY-MM-DD. Omit for all of them.

- `changes` (array)
- `dataAsOf` (string)

### `list_countries` (~62 tokens)

The 27 EU member states and their codes

## Common questions

### What is the EU VAT rates MCP server?

EU VAT rates is an MCP server listed in the public MCP registry as io.github.duty27/eu-vat. Standard VAT rate in any EU member state on any date since 2016. Offline, no API key. This page covers its npm package (@duty27/eu-vat-mcp).

### Is the EU VAT rates MCP server safe to use?

EU VAT rates scores 87 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 6 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the EU VAT rates MCP server expose?

EU VAT rates exposes 4 tools: get_standard_rate, get_rate_history, list_rate_changes, list_countries. Their descriptions and schemas cost roughly 550 tokens of context every time the server is loaded.

### Is the EU VAT rates MCP server still maintained?

EU VAT rates is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the EU VAT rates MCP server under?

EU VAT rates declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the EU VAT rates MCP server?

VerifyMCP ran 16 checks on EU VAT rates, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
