Install

How do I install the HemmaBo Host Booking Engine MCP server?

HemmaBo Host Booking Engine is a hosted endpoint at https://www.hemmabo.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Tool Tokens
get_verified_stay_offer ~511

Fetch, verify, and render a live host-domain signed VRP stay offer for exact dates and guest count. Verifies Ed25519 JWS against domain JWKS. Call after hemmabo_search_properties returns a host domain, or after verify_vacation_rental_node confirms a domain from outside search, always before quoting final price or a booking link. Read-only: must not lock a quote, create a booking, collect guest details, or start checkout. Route booking only to the signed direct_booking_url; fall back to hemmabo_booking_negotiate/hemmabo_booking_checkout only when this call returns no signed offer, for a configured non-VRP deployment, after explicit user confirmation. The parameters work as a set: pass the same domain, checkIn, checkOut and guests the guest used at search; checkIn must be strictly before checkOut, and the resulting night count — not the dates themselves — drives the signed price and the host capacity check, so changing either date re-prices the offer. Always pass language as the guest's actual conversation language so the rendered widget matches the guest; it never affects the signed price or availability, only formatting.

NameTypeReqDescription
checkInstringyesRequested arrival date in YYYY-MM-DD format (e.g. '2026-11-14'). Must be strictly before checkOut. Use the same dates the guest requested in search.
checkOutstringyesRequested departure date in YYYY-MM-DD format (e.g. '2026-11-17'). Must be strictly after checkIn. Guest does not stay the departure night.
domainstringyesHost-owned domain without protocol or path (e.g. 'villaakerlyckan.se', 'myvilla.it'). Invalid: 'https://...', paths, ports, or booking URLs.
guestsintegeryesTotal guest count as positive integer (e.g. 2, 4). Used by the host node for capacity validation and guest-tier pricing on the signed offer.
languagestringThe guest's conversation language, as a BCP-47 tag (e.g. 'en', 'sv', 'de', 'sv-SE') — ALWAYS pass this, matching the language the guest is chatting in, so the rendered widget's labels, dates and curr…

No examples provided.

hemmabo_booking_cancel ~380

Cancel a confirmed booking and process the Stripe refund per host cancellation policy. Use when the guest explicitly requests cancellation — if the guest wants new dates instead of ending the stay, use hemmabo_booking_reschedule instead. Do not use for pending/unpaid bookings — those expire automatically. To preview the applicable policy first, read cancellationPolicy from hemmabo_booking_status. Requires Authorization: Bearer token (MCP_API_KEY or OAuth); rate-limited per token. Destructive and idempotent in effect: a repeat cancel is refused as already cancelled and never triggers a second refund. reservationId is the booking UUID from hemmabo_booking_checkout or hemmabo_booking_create — never a propertyId — and must be paired with the guestToken issued for that same booking. reason is optional free text shown to the host; when omitted the host sees 'Cancelled via MCP'.

NameTypeReqDescription
guestTokenstringyesPer-booking secret returned by hemmabo_booking_create / hemmabo_booking_checkout (the booking's guest_token, a UUID). Required to view or modify this specific booking — a valid Bearer token alone is…
reasonstringHuman-readable cancellation reason for the host (e.g. 'Travel plans changed', 'Flight cancelled'). Optional; omit when the guest did not give a reason.
reservationIdstringyesBooking or reservation UUID from hemmabo_booking_checkout or hemmabo_booking_create (e.g. '7c9e6679-7425-40de-944b-e07fc1f90ae7'). Required to look up, cancel, or reschedule the same booking record.
NameTypeReqDescription
errorstringPresent only when isError=true.
refundobjectRefund payload returned by cancel-booking edge function, when present.
reservationIdstringyes
statusstringyesFinal booking status after cancellation.

No examples provided.

hemmabo_booking_checkout ~695

Create a fallback non-VRP booking and return a host-configured Stripe checkout URL. Use only after explicit user confirmation when no signed VRP direct_booking_url is available; when get_verified_stay_offer returns one, route the guest there instead. Use hemmabo_booking_create to record a pending booking without collecting payment yet. Behavior: existing bookings are never modified — availability is checked and dates briefly locked first; conflicts fail before anything is created or charged. Success creates exactly one pending booking and one Stripe Checkout Session on the host's connected account, returning paymentUrl, reservationId, and a one-time guestToken (required for status/cancel/reschedule). Only the Stripe webhook confirms the booking; unpaid pending bookings expire automatically. Not idempotent — check hemmabo_booking_status before retrying. Params: pass quoteId only for the exact propertyId/dates/guests locked by hemmabo_booking_negotiate (valid 15 min); omit to price fresh. channel selects which locked total is used; paymentMode changes only the handoff form, never the price. Requires Authorization: Bearer token (MCP_API_KEY or OAuth); rate-limited per token.

NameTypeReqDescription
channelstringPricing channel selector. 'federation' (default for agent flows): direct host-source total. 'public': standard website rate without agent channel pricing. Omit to use federation.

checkOutstringyesDeparture date in ISO 8601 calendar format YYYY-MM-DD (e.g. '2026-07-22'). Must be strictly after checkIn on the same calendar. The guest does not stay the departure night.
guestEmailstringyesPrimary guest email in RFC 5322 format (e.g. 'anna@example.com'). Used for booking confirmation and host contact; must be deliverable.
guestNamestringyesPrimary guest full name as plain text (e.g. 'Anna Svensson'). Stored on the booking for host confirmation; use the name the guest provided.
guestPhonestringPrimary guest phone in E.164 format with country code (e.g. '+46701234567'). Optional; omit when unknown. Recommended for check-in coordination.
guestsintegeryesTotal number of guests as integer >= 1 (e.g. 4).
paymentModestringStripe payment flow. 'checkout_session' (default): returns a browser redirect URL. 'payment_intent': returns client_secret for embedded/agentic payment integrations. Omit to use checkout_session.
propertyIdstringyesStable property UUID from hemmabo_search_properties (e.g. '550e8400-e29b-41d4-a716-446655440000'). Pass the exact UUID string — never a property name, host domain, or booking URL.

hemmabo_booking_create ~539

Create a pending direct booking without online payment for configured non-VRP fallback deployments. Use only after explicit user confirmation, with a propertyId from search, and only when no signed VRP direct_booking_url is available. For signed VRP offers, route to the signed host-domain URL instead. Requires Authorization: Bearer token (MCP_API_KEY or OAuth); rate-limited per token. Writes exactly one pending booking awaiting the host's decision; availability is checked first — conflicts or a stale calendar fail the call before anything is written. Not idempotent — check hemmabo_booking_status before retrying on timeout. There is no price or quoteId parameter — the node prices the stay itself at creation (gap-night pricing applies automatically). The booking is identified by propertyId + the checkIn/checkOut range + guests; guestName and guestEmail are required for host confirmation, guestPhone is optional. Returns bookingId and a one-time guestToken for later status/cancel/reschedule.

NameTypeReqDescription

hemmabo_booking_negotiate ~455

PRICE LOCK, not negotiation: the host's price is fixed — this tool never bargains, discounts, or alters it; it only freezes the current host-source price for 15 minutes so it cannot change during checkout. It refuses to lock dates the property's calendar cannot deliver and returns alternative bookable windows instead. Use it only in the non-VRP fallback checkout flow, when no signed direct_booking_url is available and the user explicitly asks to lock a price. Never use this for search, availability, VRP offers, rendering a stay-offer widget, or verified-offer display — use get_verified_stay_offer instead. Requires Authorization: Bearer token (MCP_API_KEY or OAuth); rate-limited per token. Not idempotent: each call writes a new snapshot; validUntil is fixed at creation and never extended — re-locking returns a new quoteId. The lock freezes both the public and the direct host-source total; hemmabo_booking_checkout's channel picks which one is redeemed. Redeem the quoteId only for the identical propertyId + checkIn/checkOut + guests, and only until validUntil — changing any of them requires a new quote. Night count and guest count together select the locked price tier.

NameTypeReqDescription

hemmabo_booking_quote ~348

Get a detailed pricing quote for a specific property, dates, and guest count. Use this tool after confirming availability to show the user exact pricing before booking. Do NOT use before checking availability — the quote may be invalid if dates are unavailable. Returns the final host-source total for the booking flow, per-night breakdown, and package pricing context. All prices are integers in the property's local currency (e.g. SEK). The quote is the propertyId priced for the exact checkIn/checkOut range and guests; the night count and party size together select the price tier, so changing any of them re-quotes.

NameTypeReqDescription

hemmabo_booking_reschedule ~474

Reschedule a confirmed or pending booking to new dates with automatic repricing and Stripe charge/refund. Use when the guest wants to change dates on an existing booking — if the guest wants to end the stay entirely rather than move it, use hemmabo_booking_cancel instead. Do not use if cancelled or if a protocol compatibility client reports completed — check hemmabo_booking_status first. Requires Authorization: Bearer token (MCP_API_KEY or OAuth). Destructive write: the original dates are released back to the host calendar and the original price no longer applies — the booking keeps the same reservationId (updated in place, never recreated), and the price difference is charged or refunded via Stripe. Rate-limited per token. Identify the existing booking by reservationId, then give the new stay as newCheckIn/newCheckOut (newCheckIn strictly before newCheckOut); the new night count re-prices the stay exactly like a fresh quote.

NameTypeReqDescription

hemmabo_booking_status ~341

Retrieve current status and full details of an existing booking by reservationId. Use to confirm checkout/create succeeded or before cancel/reschedule. Do NOT use for property discovery, availability, or pricing — use hemmabo_search_properties, hemmabo_search_availability, or hemmabo_booking_quote for those. Requires Authorization: Bearer token (MCP_API_KEY or OAuth); rate-limited per token. Read-only against the database — never writes, so it is safe to poll after a checkout timeout — but returns guest PII (name, email). reservationId is the booking UUID returned by hemmabo_booking_checkout or hemmabo_booking_create — never a propertyId — and guestToken is the secret issued with that same booking: a mismatched pair reveals nothing, not even that the booking exists. Without a reservationId there is no booking to look up yet.

hemmabo_host_onboarding_link ~432

Return a safe HemmaBo onboarding handoff URL for a vacation-rental host who wants their own booking website or booking engine. Not for guests — guests should use hemmabo_search_properties instead. Use after explaining the fit or when the host asks to start; if the host is still evaluating whether HemmaBo fits, run hemmabo_host_readiness_check first — it already returns the same prefilled URL in its next_step. This tool is read-only and does not create a HemmaBo account, buy a domain, configure Stripe, write to Supabase, or provision a booking site. It returns the URL, what the host gets, and what the host should prepare. All parameters are optional prefill: they never change where the host lands — the URL always opens the same onboarding page with the passed details filled in; blank values are simply left out, and nothing is stored server-side.

NameTypeReqDescription
citystringCity or municipality (e.g. 'Kävlinge', 'Florence'). Optional; used in onboarding URL prefill when provided.
countrystringCountry where the property operates (e.g. 'Sweden', 'Italy', 'Morocco'). Optional; improves onboarding URL locale and fit assessment.
domainstringHost-owned domain without protocol or path (e.g. 'villaakerlyckan.se', 'myvilla.it'). Optional; omit when the host has not chosen a domain yet. Invalid: 'https://...', paths, ports, or booking URLs.
languagestringISO 639-1 language hint for onboarding copy (e.g. 'sv', 'en', 'de', 'fr'). Optional; omit to default to English.
propertyNamestringProperty or business display name (e.g. 'Villa Åkerlyckan'). Optional; carried into onboarding URL when provided.
regionstringRegion or area (e.g. 'Skåne', 'Toscana', 'Marrakech-Safi'). Optional; narrows onboarding handoff and proof examples.

hemmabo_host_readiness_check ~643

Read-only fit check for a vacation-rental host evaluating HemmaBo for their own booking website or booking engine. Use when the user is a host or property owner, not a guest booking a stay; guests should use hemmabo_search_properties instead. Returns a fit verdict, what the host gets, the setup inputs to prepare, and a safe onboarding next step. Does not create an account, buy a domain, configure Stripe, store host data, or provision a website. When the host is ready to start, follow up with hemmabo_host_onboarding_link. Only five inputs sharpen the fit verdict: a domain (hasOwnDomain or domain), currentChannels, one location signal (city/region/country), and the wants* booleans, which count unless explicitly false — omitting them never lowers the verdict; propertyName and preferredLanguage only prefill the onboarding URL, and with no inputs the summary is generic.

NameTypeReqDescription
citystringCity or municipality (e.g. 'Kävlinge', 'Florence'). Optional; used in onboarding URL prefill when provided.
countrystringCountry where the property operates (e.g. 'Sweden', 'Italy', 'Morocco'). Optional; improves onboarding URL locale and fit assessment.
currentChannelsarrayOptional list of channels the host uses today. Omit when unknown. Helps assess migration fit from OTAs to their own booking website.
domainstringHost-owned domain without protocol or path (e.g. 'villaakerlyckan.se', 'myvilla.it'). Optional; omit when the host has not chosen a domain yet. Invalid: 'https://...', paths, ports, or booking URLs.
hasOwnDomainbooleanTrue if the host already owns a domain or explicitly wants one (e.g. true for 'I have villaakerlyckan.se'). False or omit when still undecided.
preferredLanguagestringISO 639-1 language hint for onboarding copy (e.g. 'sv', 'en', 'de', 'fr'). Optional; omit to default to English.
propertyNamestringProperty or business display name (e.g. 'Villa Åkerlyckan'). Optional; carried into onboarding URL when provided.
propertyTypestringProperty category enum. Optional; omit when unknown. 'villa'/'holiday_home' fit best; 'hotel' may indicate a poor HemmaBo fit for large chains.
regionstringRegion or area (e.g. 'Skåne', 'Toscana', 'Marrakech-Safi'). Optional; narrows onboarding handoff and proof examples.
wantsAiAgentBookingbooleanTrue if the host wants AI agents (ChatGPT, Claude, Cursor) to discover and book via their own official website. False or omit when they only want a guest website.
wantsDirectPaymentsbooleanTrue if the host wants Stripe Connect payouts direct to their account. False or omit when they expect HemmaBo to be merchant of record (not supported).

hemmabo_search_availability ~456

Check whether a specific property is available for the requested dates. Use this tool after the user has selected a property from hemmabo_search_properties and wants to confirm availability before getting a quote. Do NOT use for general browsing — use hemmabo_search_properties instead. Read-only, open to anonymous callers (no Bearer token), and rate-limited: checking availability never places a hold or reserves dates. Returns available=true/false with conflict details and, when unavailable, the host node's own next available window (alternativeDates, at most one entry — the same window the node's /api/availability reports, never a platform-invented date); a stale inbound calendar sync blocks an available answer (fails closed with calendar_freshness) instead of guessing. Omit guests to check dates only; pass it to price the alternative windows and to gate capacity — counts above the property's maximum return available=false (guests_exceed_max) with no alternatives. Stays shorter than the host's effective minimum nights return available=false with reasonCode min_nights_violation — extend the stay rather than shifting dates. The verdict always matches the host node's own availability API.

NameTypeReqDescription
checkInstringyesArrival date in ISO 8601 calendar format YYYY-MM-DD (e.g. '2026-07-15'). Must be today or later in the property's timezone. Must be strictly before checkOut; together they define the stay length used…
checkOutstringyesDeparture date in ISO 8601 calendar format YYYY-MM-DD (e.g. '2026-07-22'). Must be strictly after checkIn on the same calendar. The guest does not stay the departure night.
guestsintegerOptional guest count (e.g. 4). Omit when only checking date availability without pricing. When provided, alternative date windows in the response include live host-source totals for that guest count.
propertyIdstringyesStable property UUID from hemmabo_search_properties (e.g. '550e8400-e29b-41d4-a716-446655440000'). Pass the exact UUID string — never a property name, host domain, or booking URL.
NameTypeReqDescription
alternativeDatesarrayThe host node's own next available window (at most one) to offer when the requested dates are unavailable — identical to the node's /api/availability nextAvailable. Empty when the node offers none.
availablebooleanyesTrue if the property is bookable for the entire range.

hemmabo_search_properties ~453

Search available vacation rental properties by location and travel dates. Use when the user wants to find or browse places to stay. Discovery only — call get_verified_stay_offer with the host domain and same dates before the final answer so the client can render the verified stay offer widget; never quote a final price or booking link from search alone. Do NOT use when the user already has a propertyId or host domain. Returns propertyId, host domain, live availability, host-source pricing, and capacity. Parameters combine as one filter with guests and the checkIn/checkOut range (checkIn strictly before checkOut): region matches broadly against region, city, and country names, while country matches the country field alone — omit both and the search spans every published property. Capacity misses are excluded; date-unavailable matches return separately in unavailableMatches with up to three alternative windows.

NameTypeReqDescription
checkInstringyesArrival date in ISO 8601 calendar format YYYY-MM-DD (e.g. '2026-07-15'). Must be today or later in the property's timezone. Must be strictly before checkOut; together they define the stay length used…
checkOutstringyesDeparture date in ISO 8601 calendar format YYYY-MM-DD (e.g. '2026-07-22'). Must be strictly after checkIn on the same calendar. The guest does not stay the departure night.
countrystringCountry name to filter by (e.g. 'Sweden', 'Italy', 'Morocco'). Partial case-insensitive match. Provide at least one of region or country; omit when region already narrows the destination.
guestsintegeryesTotal guest count as a positive integer (e.g. 2, 4, 6). Used for capacity filtering and staircase pricing tiers. Properties with maxGuests below this value are excluded from search results.
regionstringRegion, area, or destination to search within (e.g. 'Skåne', 'Kävlinge', 'Toscana', 'Bavaria'). Partial case-insensitive match. Provide at least one of region or country; omit only when country alone…

checkOutstringEchoed check-out date (YYYY-MM-DD).
errorstringPresent only when isError=true.
guestsintegerEchoed guest count.
propertiesarrayAvailable properties matching the search criteria, with live host-source pricing.

No examples provided.

verify_vacation_rental_node ~265

Verify that a vacation-rental host domain is a valid Vacation Rental Protocol (VRP) node before trusting it. Reads the domain's .well-known/vacation-rental.json and JWKS. Read-only trust check: no availability, pricing, booking, or payment — do NOT use it to answer those questions. Use when a host domain arrives from outside search (user-typed or third-party); domains returned by hemmabo_search_properties can go straight to get_verified_stay_offer. On success, call get_verified_stay_offer with the same domain and stay dates. The single input is the host domain as a bare hostname (no scheme or path); public domains only — IPs, ports, and local/private hostnames are refused. Pass the node's canonical domain exactly — www and apex are distinct identities, and verification fails when the domain's declared canonical_domain differs from the one you passed. Verification reads that domain's own .well-known and JWKS, so the result is only as trustworthy as the exact domain you pass.

NameTypeReqDescription
domainstringyesHost-owned domain without protocol or path (e.g. 'villaakerlyckan.se', 'myvilla.it'). Invalid: 'https://...', paths, ports, or booking URLs.
NameTypeReqDescription
discovery_urlstringThe .well-known vacation-rental discovery URL read from the host domain.
domainstringyesEchoed canonical host domain that was checked.
errorstringPresent when verified=false or the node cannot be checked.
jwks_urlstringHost-domain JWKS URL containing the Ed25519 public keys used to verify signed offers.
protocolstringProtocol identifier discovered on the host domain. A valid node declares exactly 'vacation-rental-protocol' in its .well-known/vacation-rental.json protocol field, and that is the value returned here.
protocol_versionstringVRP version declared by the host discovery document.
signingobjectSummary of accepted signing algorithms, key ids, and signing-key checks.
verifiedbooleanyesTrue only when discovery, JWKS, signing metadata, and verified-offer endpoint checks pass.
verified_stay_offer_urlstringHost-domain endpoint template or URL used to request signed verified stay offers.
