## MCP tools (9)

### `calculate_car_tax` (~544 tokens)

Calculate UK car tax (VED)

Calculate annual UK vehicle tax (VED / road tax) for a car. Handles all three UK systems: cars first registered before 1 March 2001 (taxed on engine size, so engine_size_cc is required), 1 March 2001 to 31 March 2017 (CO2 bands £20–£790, so co2 is required), and from 1 April 2017 (flat standard rate). Also works out the Expensive Car Supplement: over £40,000 list price when new for petrol, diesel and alternative fuel; over £50,000 for a zero-emission car first registered on or after 1 April 2025; and none for a zero-emission car first registered before 1 April 2025, whatever it listed for. The boundaries are dates, so registration_date gives an exact answer where the year alone is ambiguous. If an input the car's tax system needs is missing, the tool returns an error naming it rather than a figure. Use for questions about UK car tax, road tax or VED.

Input parameters:

- `co2` (number): CO2 emissions in g/km, from the V5C. Required for cars first registered 1 March 2001 – 31 March 2017. For cars registered from 1 April 2017 it only sets the one-off first-year rate. Ignored for pre-2…
- `engine_size_cc` (number): Engine size in cc. Required for cars first registered before 1 March 2001; not used otherwise.
- `fuel` (string, required): Fuel type. Use "alternative" for hybrid/LPG, "diesel-rde2" only for diesels meeting RDE2.
- `list_price_when_new` (number): Original list price in GBP when the car was new. Needed only to work out the Expensive Car Supplement — based on the price when NEW, not what you pay for it used.
- `registration_date` (string): Full date of FIRST registration as YYYY-MM-DD, from the V5C. Optional but preferred: every UK VED boundary is a date (1 March 2001, 1 April 2017, 1 April 2025), so the year alone cannot tell a zero-e…
- `registration_year` (integer, required): Year the car was FIRST registered (not the year it was bought). This decides which tax system applies.

### `check_clean_air_zone` (~191 tokens)

Check ULEZ / Clean Air Zone charges

Check whether a car is compliant with UK clean air zones (London ULEZ, Bristol, Birmingham) and what it would cost to drive into them. Returns compliance, the daily charge per zone, and estimated annual cost. Only 3 of the 8 English charging zones charge private cars; Scotland uses Low Emission Zones, which issue penalties rather than a daily charge. Needs the registration year and fuel (the year is not needed for an electric car); a missing input returns an error naming it. Use for ULEZ, CAZ, clean air zone or emissions-charge questions.

Input parameters:

- `days_per_year` (integer): Days per year the driver would enter a charging zone, 0–366. Defaults to 250 (a daily commute).
- `fuel` (string, required): Fuel type.
- `registration_year` (integer): Year the car was first registered. Required unless fuel is "electric".

### `check_mot_due_date` (~202 tokens)

Work out MOT due date

Work out when a car's MOT test is due, and the earliest date it can be tested without losing its renewal date. These are Great Britain (DVSA) rules: a car's first MOT falls on its third anniversary of registration, then annually. Northern Ireland is tested by the DVA, where the first test is not due until four years old. Testing earlier than one calendar month minus a day before expiry resets the renewal date. Pass first_registered for a car that has never had an MOT, or mot_expires for one that has. Use for questions about MOT due dates, MOT timing, or when a car needs testing.

Input parameters:

- `first_registered` (string): Date the car was first registered, ISO format YYYY-MM-DD. Use this for a car that has never had an MOT.
- `mot_expires` (string): Date the current MOT expires, ISO format YYYY-MM-DD. Use this for a car that already has an MOT.

### `mot_outlook` (~289 tokens)

Estimate MOT pass odds by age and mileage

Odds that a used car passes its next MOT first time, for its age and mileage, counted from DVSA's own MOT test records with odometer readings (Great Britain) — and how those odds move one mileage band lower or higher for a car of the same age. Pass make and model as well: for the models we cover it adds that model's pass rate at the same mileage, compared fairly against cars of the same ages, and it says plainly when a model is not covered rather than guessing. It is a rate across the tested fleet, not a prediction for one car. Use when someone asks whether a high-mileage car will pass its MOT, how much mileage matters for an MOT, or whether a particular used car is likely to need MOT work.

Input parameters:

- `age_years` (integer): Age in whole years, only if the registration year is not known.
- `make` (string): Manufacturer, e.g. "Ford". Optional, but needed (with model) for the model-level comparison.
- `mileage` (integer, required): Current odometer reading in miles.
- `model` (string): Model, e.g. "Focus". Optional; see make.
- `registration_year` (integer): Year the car was FIRST registered (V5C), e.g. 2016. Age is counted from it the way the DVSA figures were. Preferred over age_years.

### `get_model_reliability` (~140 tokens)

Get model reliability and MOT pass rates

Get known common faults, best and worst model years, and real DVSA MOT first-time pass rates for a specific used car model in the UK. The MOT pass rates are counted from millions of real UK test records and are age-matched against the national average. Call with no model_slug to list the models covered. Use when someone asks whether a specific model is reliable, what goes wrong with it, which year to buy or avoid, or what to check before buying one.

Input parameters:

- `model_slug` (string): Model identifier, e.g. "ford-focus-common-faults-uk". Call with no argument to list every available model.

### `search_used_cars` (~345 tokens)

Search used cars for sale

Search live used cars for sale from UK dealers on Autoza, with current asking prices in GBP and mileage in miles. Returns a canonical autoza.co.uk URL, the town or area, and the vehicle type for each result. Searches cars unless vehicle_type asks for vans, motorcycles or other stock. If nothing matches every filter, optional filters are relaxed one at a time and the response lists which ones. Use when someone wants to find, browse or compare actual vehicles currently for sale in the UK.

Input parameters:

- `body_type` (string): e.g. "hatchback", "estate", "suv", "saloon".
- `fuel_type` (string): e.g. "petrol", "diesel", "electric", "hybrid".
- `limit` (integer): Max results, 1–25. Defaults to 10.
- `location` (string): UK city or region, e.g. "Manchester", "Belfast".
- `make` (string): Manufacturer, e.g. "BMW", "Ford".
- `max_price` (number): Maximum price in GBP.
- `max_year` (integer)
- `min_price` (number): Minimum price in GBP.
- `min_year` (integer)
- `model` (string): Model name, e.g. "Focus", "3 Series".
- `transmission` (string): e.g. "manual", "automatic".
- `vehicle_type` (string): Vehicle type. Defaults to "car". Results are filtered on the vehicle type each listing is recorded under. Pass "van", "motorcycle", "motorhome", "truck" or "caravan" for other stock.

### `estimate_running_costs` (~144 tokens)

Estimate a listed car's running costs

Estimate what a specific car on Autoza costs to own for a year — road tax, fuel, servicing, MOT and insurance, plus three-year depreciation where it can be worked out. Pass the listing URL or id returned by search_used_cars. Components that cannot be worked out from the listing are omitted rather than guessed, and the response says which. A car that has sold or been withdrawn comes back as status no_longer_for_sale rather than an estimate.

Input parameters:

- `listing_id` (string): Listing id, if you have it instead of the URL.
- `listing_url` (string): Full autoza.co.uk listing URL as returned by search_used_cars.

### `get_uk_price_guide` (~177 tokens)

Get UK asking-price guide

Get current UK used-car asking-price guidance from live dealer listings on Autoza — typical, lowest and highest asking price, optionally narrowed to a make or model. Cars unless vehicle_type asks for vans, motorcycles or other stock. Prices are GBP and reflect what dealers are asking right now, not trade or valuation estimates. Use to answer "what do X cost used in the UK" or to sanity-check whether an advertised price is reasonable.

Input parameters:

- `make` (string): Optional: narrow to a manufacturer.
- `model` (string): Optional: narrow to a model.
- `vehicle_type` (string): Vehicle type. Defaults to "car". Results are filtered on the vehicle type each listing is recorded under. Pass "van", "motorcycle", "motorhome", "truck" or "caravan" for other stock.

### `ask_about_car` (~223 tokens)

Ask about a listed car

Answer a buyer's specific questions about ONE car listed on Autoza — previous owners, service history, warranty, number of keys, previous use, and the core specification. Every answer comes from the dealer's own listing and says so: it is what the dealer states, not an independent inspection. A question the listing does not answer comes back as unknown, which does not mean no. Pass the listing URL or id returned by search_used_cars. If the car has sold or been withdrawn, the response is status no_longer_for_sale with no answers. When the selling dealer has opted in to showing MOT history, the response also carries mot_history: that car's official DVSA MOT test record.

Input parameters:

- `include_unanswered` (boolean): Default true. Keep the questions we cannot answer in the response so the buyer can be told what is unknown.
- `listing_id` (string): The listing id, if you have it instead of the URL.
- `listing_url` (string): The autoza.co.uk/listing/... URL returned by search_used_cars.
