What this MCP does

Supports searching, comparing, valuing, buying, selling, reserving, and messaging about used bicycles on a UK marketplace.

Capabilities

Tools

34 tools
check_stolen
Check if a UK bicycle is reported stolen by serial number. Cyclesite checks an international stolen-bike registry and theft reports filed by riders, the unique data we own. Per-serial rate-limited (3/hour) to prevent enumeration. Example: 'is the bike with serial WTU123456 reported stolen?'. Live data, cross-references multiple registries on every call.

compare_bikes
Side-by-side comparison of up to 3 bikes (each by brand+model[+year]). Returns spec sheets and valuations together so the user can pick. Reuses get_spec_sheet + get_valuation server-side. Example: 'compare a Trek Domane SL 6 against a Specialized Roubaix Comp'.

Output schema 
{'type': 'object'}
draft_listing
Sell-side helper: turn a seller's raw facts into a polished Cyclesite listing draft (title, description, suggested price, photo plan). Does NOT publish — for actual publication use publish_listing (requires OAuth). Useful for previewing what a listing would look like. Example: 'help me draft a listing for my 2021 Specialized Allez, very good condition, in Bristol'.

fetch
OpenAI deep-research / company-knowledge compatibility. Fetch the full document for a Cyclesite listing id (returned by the search tool). Returns { id, title, text, url, metadata } — text is a plain-prose summary of the listing's description and specs, suitable for direct quoting in deep-research answers.

find_similar_listings
Given a Cyclesite listing slug, return up to 5 similar active listings (same category, ±25% price, same brand or frame size weighted higher). Use when the user is interested in one bike and wants alternatives. Example: 'show me bikes like that one'.

get_listing_detail
Full details for a specific bike listing on Cyclesite — specs, condition, frame number presence, photos, delivery, seller's city. Provide the URL slug returned by search_bikes or get_recent_listings.

Read the buyer's own Cyclesite message threads and any seller replies. Call with no args to list your conversations; pass a threadId to read one thread's messages.

get_size_guide
Frame-size recommendation for a rider's height and bike category, the same chart Cyclesite publishes at /bike-size-calculator (height to inside leg to seat tube), refined by real UK listing data where riders' declared heights are available. Children are sized by wheel diameter instead and the tool says so. Example: 'I'm 178cm — what road-bike size do I need?'.

get_valuation
What a used UK bike is worth right now, Cyclesite's flagship tool. Returns median, range, a measured price-by-model-year curve, confidence level, and comparable active listings. Pass `year` when the user names one and the answer is resolved against that model year's own measured median and confidence interval, instead of the all-years median. Sourced from real UK market prices, the last-advertised asking prices bikes are listed for (not confirmed sale prices), refreshed nightly. Example: 'what's a 2022 Trek Domane SL 6 worth?'.

grade_listing_quality
Categorical quality grade for a Cyclesite listing (excellent / good / fair / weak) plus up to 2 wins and 2 flags. Helps a buyer assess trustworthiness; helps a seller self-audit. Example: 'is this listing trustworthy?' (provide the slug). Note: returns the *categorical* judgement only, not the underlying score (intentional to avoid gaming).

Paginated UK bike-brand catalogue from Cyclesite, ordered by stock level. Use to validate a brand name, surface options to a user, or paginate the catalogue. Stock counts are returned as bands (none / 1-5 / 6-25 / 26-100 / 100+) — Cyclesite doesn't expose precise per-brand inventory. Example: 'what brands of e-bike are available?'.

list_models_for_brand
Models for a brand on Cyclesite (paginated). Returns model names, year ranges, in-stock flag. Example: "what Trek road bikes are available?" → list_brands(q:"Trek") → list_models_for_brand(brandSlug:"trek", category:"road").

make_enquiry
Send an enquiry to a Cyclesite seller on the buyer's behalf. It's saved to the buyer's Cyclesite inbox and the seller is notified. Per-buyer-per-listing daily cap (2/day) prevents spam. Read the seller's reply with get_my_messages. Requires OAuth scope `enquiries:respond` (note: the scope name is shared with seller-side replies). Example: 'message the seller of that Trek and ask if they'd take £1,400 collection only in Manchester next Saturday'.

publish_listing
Publish a Cyclesite listing on the user's behalf. Multi-step: first call (no draftId) returns a phone-friendly photo upload URL; once 3+ photos are uploaded, the next call returns either step:'live' (listing is free, no payment needed) or step:'payment_required' with a Stripe Checkout URL. Idempotent — keep calling with the same draftId until step:'live'. Requires OAuth scope `listings:publish`. Example flow: user says 'sell my Trek Domane' → call publish_listing → assistant directs user to upload URL → user uploads → call again → step:'live' → seller receives a confirmation email with a 24h undo link.

reserve_listing
Hold a Cyclesite listing for 24 hours so other buyers can't claim it while the user decides. The hold is free and advisory (the seller isn't obligated to honour it — message the seller to confirm). Paid deposit-backed holds are coming soon; do not offer deposits today. The first UK marketplace where a buyer can COMMIT inside an AI conversation. Requires OAuth scope `listings:manage`. Example: 'put a hold on that Trek for me, I want to view it Saturday'.

save_search
Subscribe the user to alerts for new Cyclesite listings matching a filter — the AI assistant will then proactively notify them when a matching bike appears (price drop or fresh listing). Requires OAuth scope `listings:read` (read-only on data, but this is technically a write — it creates a SavedSearch row on the user's account). Examples: 'let me know when a Trek Domane SL 6 in Manchester under £2,000 appears', 'alert me to any e-MTB drops below £2,500 in Yorkshire'. Each user is capped at 50 active alerts.

suggest_listing_price
For a seller about to list: suggested ask, floor, and ceiling for their bike's brand+model[+year][+condition] on the UK market. Same measured UK used-price data as get_valuation but framed as seller guidance. Pass `year` when the seller names one — the ask is then anchored on that model year's own median rather than the all-years median. Example: 'I'm selling a 2021 Specialized Allez in good condition — what should I ask?'.
