## 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 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - The endpoint enforces authorisation, but returns a challenge with no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http.
- **Schema Quality & AI Usability**: 0/100
  - Schema blocked by authentication: the endpoint requires auth we don't have to read it.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Tool Safety**: 0/100
  - Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Capabilities**: 0/100
  - Capabilities blocked by authentication: the endpoint requires auth we don't have to read them.

**Unverified: 6 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the io.github.physics-star-cat/databutler-uk-vehicle-rules MCP server?

## MCP tools (1)

### `uk_vehicle_rules_lookup` (~294 tokens)

UK vehicle tax (VED) & MOT rules

UK vehicle tax (VED) and MOT rules for 2026-27, verified against gov.uk, by category: ved-first-year (first-year rate by CO2 band for cars registered on or after 1 April 2017, petrol/RDE2-diesel and other-diesel columns), ved-standard (the flat rate from the second year and the Direct Debit surcharges), ved-expensive-car (list price threshold, annual supplement, years applied), ved-2001-2017 (bands A–M), ved-pre-2001 (engine size), ved-electric (zero-emission cars taxable since 1 April 2025), historic (40-year MOT exemption and the vehicle-tax exemption build date), mot (first MOT at 3 years, maximum fees by class, early renewal, retests, exemptions) and penalties (no MOT, dangerous vehicle, untaxed vehicle). Each figure carries its value, unit, the quoted line from the page, its source URL, effectiveFrom and the previous year's value; the answer carries verifiedDate, freshness and a citation permalink. No category returns the listing; an unknown category answers covered:false with the nearest keys.

Input parameters:

- `category` (string): one of: ved-first-year, ved-standard, ved-expensive-car, ved-2001-2017, ved-pre-2001, ved-electric, historic, mot, penalties (omit to list all)

## Common questions

### What is the io.github.physics-star-cat/databutler-uk-vehicle-rules MCP server?

io.github.physics-star-cat/databutler-uk-vehicle-rules is an MCP server listed in the public MCP registry as io.github.physics-star-cat/databutler-uk-vehicle-rules. UK vehicle tax (VED) bands, expensive-car supplement, EV rules and MOT fees, sourced. This page covers its hosted endpoint (https://databutler.dev/api/mcp/uk-vehicle-rules).

### Is the io.github.physics-star-cat/databutler-uk-vehicle-rules MCP server safe to use?

io.github.physics-star-cat/databutler-uk-vehicle-rules scores 33 out of 100 on VerifyMCP. 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 io.github.physics-star-cat/databutler-uk-vehicle-rules MCP server expose?

io.github.physics-star-cat/databutler-uk-vehicle-rules exposes 1 tool: uk_vehicle_rules_lookup. Their descriptions and schemas cost roughly 294 tokens of context every time the server is loaded.

### Does the io.github.physics-star-cat/databutler-uk-vehicle-rules MCP server require authentication?

Yes. io.github.physics-star-cat/databutler-uk-vehicle-rules asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the io.github.physics-star-cat/databutler-uk-vehicle-rules MCP server still maintained?

io.github.physics-star-cat/databutler-uk-vehicle-rules is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the io.github.physics-star-cat/databutler-uk-vehicle-rules MCP server?

VerifyMCP ran 5 checks on io.github.physics-star-cat/databutler-uk-vehicle-rules, covering TLS certificate, Authorization, HTTPS, HSTS header and 1 more. 6 items could not be completed, a gap on our side rather than a finding about io.github.physics-star-cat/databutler-uk-vehicle-rules: Transport, Schema quality, Stability, Tool coverage and 2 more. 6 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
