LORO for AI assistants: ready-made links on loro.de

As a developer and producer of drains, pipes and fittings, LORO is able to provide customers with safe and reliable complete systems with measured and calculated performance verification. At the LOROWERK site in Bad Gandersheim, research, development, production, sales and service work hand in hand.

Provider: LOROWERK K.H.Vahlbrauk GmbH & Co.KG

Deutsche Fassung: https://www.loro.de/mcp

Two ways

Way 1: No setup needed

The assistant reads this page and writes prefilled links to www.loro.de (everything else on this page). Selection, calculation and tendering happen on loro.de, not in the chat. No setup and no access are needed, only this page.

Way 2: For assistants with connector support

This address https://www.loro.de/mcp is also an MCP server (Model Context Protocol). It is read-only, quotes no prices and needs no sign-in. The address must be written exactly like this: with www and without a trailing slash (other spellings are redirected, and some clients cannot handle that).

How to add it (menu names may differ by vendor, plan and app version; whether a custom connector is allowed depends on the account, and with company accounts it is often only possible through the administrator):

Claude: Customize → Connectors → Add custom connector (according to the vendor's help; the wording may change). Enter a name, enter https://www.loro.de/mcp as the address, authentication: none (“No sign in”).
ChatGPT: only in developer mode: turn it on, then create a connector or app, enter https://www.loro.de/mcp as the address, authentication: none (“No sign in”). Developer mode is not available in every plan.

Tools of the server (all read-only, no prices, no sign-in):

Tool	Purpose

`find_sales_contact`	Gives the responsible LORO contact person by postcode, or the country representation.
`build_calculation_link`	Builds a prefilled link to the online calculation; does not calculate itself.
`build_tender_link`	Builds a hand-over link to the online specification and resolves LX systems into single parts.

Rules for the assistant

You are an AI assistant and your user asks about roof drainage, parapet, balcony or flat roof drains, pipes or fittings from LORO. Then write them ready-made, prefilled links to www.loro.de.

Labels for the link patterns:

[works today]: The link pattern works as described.

Do not invent anything. Take article numbers, LX designations, values and links only from www.loro.de. Do not guess file names or article numbers. Do not call series of addresses just to check whether they exist.
Do not quote prices, even if a page shows one. Prices are available to customers with a login or from the LORO contact person.
Calculations and selections are non-binding preliminary designs. They must be checked by the responsible planner. For every sizing or system selection, pass on the following note in your own words (source: calculation PDF of the LORO online calculation).
If in doubt, name the contact person: https://www.loro.de/en/contact (Germany) or https://www.loro.de/en/contact/international (other countries).
Always write links in full, with https://www.loro.de. Encode spaces in parameters as %20.
Language: For German-speaking users use the German links, otherwise the English links (/en/…). Article texts and data sheets exist only in German and English.
Always give LX systems with their flange code, e.g. LX772-4X, never just LX772.
Rainfall intensities according to KOSTRA-DWD-2020 apply to Germany only. In other countries the user supplies their national value.

Note for rule 3:

“This online calculation does not replace professional consulting by LORO representatives. No guarantee for the correctness of this calculation! The input values must be checked for completeness and consistency with the structural conditions (e.g. rainfall intensity, runoff coefficient, area allocation, whether every low point is drained).”
“The rainfall intensity used (including the KOSTRA values suggested by postcode) is a non-binding service value without guarantee; the national and local requirements for the construction site are decisive. Selection and verification of the rainfall intensity are the responsibility of the planner.”

How to help your user

1. Product page of an article [works today]

When: The user names a LORO article number or wants data, data sheet, EAN, dimensions or documents for an article.

Link pattern:

German:  https://www.loro.de/product/<article no>/
English: https://www.loro.de/en/product/<article no>/

<article no>: LORO article number in capital letters, e.g. 19041.000X, 00100.040X, B0480.002X.

On the page: technical data, EAN, ETIM class, dimensions, material, documents (data sheet, dimensioned drawing, installation instructions), CAD links and product profile PDF.

Examples:

https://www.loro.de/en/product/19041.000X/ (LORO-X rectangular scupper 300 x 100)
https://www.loro.de/product/19041.000X/

2. Complete LX system with flange and quantity [works today]

When: The subject is a whole drain system (drain with all parts) or the user names an LX number.

Link pattern:

https://www.loro.de/en/product/LX<nr>-<flange>X/?AnzahlSysteme=<quantity>

<nr>: LX number; <flange>: flange code according to the product page or data sheet, e.g. 4.
AnzahlSysteme: whole number 1–999, optional. It prefills the quantity field of the system card. With “in Ausschreibung” (add to specification) the page takes over all parts × quantity.
Data sheet: https://www.loro.de/fileadmin/PDF/LX_Datenbl<nr>_Gesamt_ENG.pdf (German …_Gesamt.pdf). Not every LX number has one, so take the link from the page.

Examples:

https://www.loro.de/en/product/LX772-4X/ (parts list with 15 parts)
https://www.loro.de/en/product/LX772-4X/?AnzahlSysteme=4

3. Product profile PDF [works today]

When: The user wants a compact product data sheet to pass on.

Link pattern:

https://www.loro.de/fileadmin/php/produktdatenbank/steckbrief.php?artikelnr=<article no>&lang=<0|1>

lang=0 is German, lang=1 is English. The product profile never contains a price.

Example: https://www.loro.de/fileadmin/php/produktdatenbank/steckbrief.php?artikelnr=19041.000X&lang=1

4. CAD and BIM files [works today]

When: The user needs a PDF drawing, DXF, DWG, STEP or IFC.

Link pattern:

newer articles:
https://www.loro.de/fileadmin/CAD/<article no>.pdf
https://www.loro.de/fileadmin/CAD/<article no>_2D.dxf
https://www.loro.de/fileadmin/CAD/<article no>_3D.dwg

older articles:
https://www.loro.de/fileadmin/CADALT/<article no>.pdf  (or .dxf, .dwg)

3D:
https://www.loro.de/fileadmin/BIM/LORO/STEP/<article no>_3D.stp
https://www.loro.de/fileadmin/BIM/LORO/IFC3/<article no>_3D.ifc

Important: Not every file exists. Take the links from the product page (item 1) and do not guess file names.

Examples (files exist):

5. Online configurator with prefilled values [works today]

When: The user is looking for suitable drains by installation situation, drainage type, flow type, nominal diameter or roof build-up. The page shows the matching LX systems immediately, at most 30 cards.

Link pattern:

English: https://www.loro.de/en/service/online-configurator/flat-roof-drainage?entwaesserung=…&entwaesserungsart=…&stroemungsart=…&nennweite=…&dachaufbau=…
German:  https://www.loro.de/service/online-konfigurator/flachdachentwaesserung?… (same parameters)

Parameter	allowed values	Meaning
`entwaesserung`	`Attika`, `FlachdachSenkrecht`, `FlachdachWaagerecht`, `Balkon`	installation situation (parapet, flat roof vertical, flat roof horizontal, balcony)
`entwaesserungsart`	`1`, `2`, `3`	1 = main drainage, 2 = emergency drainage, 3 = combined main and emergency
`stroemungsart`	`Freispiegel`, `Druck`	free-surface flow or pressure flow
`nennweite`	`40`, `50`, `70`, `100`, `125`, `150`	DN in mm
`dachaufbau`	`BetonKaltdach`, `BetonWarmdach`, `BetonUmkehrdach`, `TrapezKaltdach`, `TrapezWarmdach`, `Kastenrinne`, `WUBeton`	selects the roof build-up tile (concrete cold, warm or inverted roof; trapezoidal cold or warm roof; box gutter; waterproof concrete); sets the installation situation (roof and parapet) and suitable flanges

Separate several values per parameter with a comma, e.g. nennweite=70,100. Unknown values are ignored.
dachaufbau can be combined with entwaesserungsart, stroemungsart and nennweite.

Examples:

Parapet, main drainage, free-surface flow, DN 100: https://www.loro.de/en/service/online-configurator/flat-roof-drainage?entwaesserung=Attika&entwaesserungsart=1&stroemungsart=Freispiegel&nennweite=100
Concrete warm roof, emergency drainage, DN 100: https://www.loro.de/en/service/online-configurator/flat-roof-drainage?dachaufbau=BetonWarmdach&entwaesserungsart=2&nennweite=100

6. Transitions between pipe systems [works today]

When: The user wants to connect LORO-X to another pipe system (cast iron, KA, PE, ST) or change the nominal diameter. Only connections maintained by the factory are shown.

Link pattern (German page only):

https://www.loro.de/service/online-konfigurator/uebergaenge?UebergangVon=<system>&UebergangAn=<system>

Valid values for UebergangVon and UebergangAn, written exactly like this (spaces as %20): LORO-X DN 32|40|50|70|80|100|125|150|200, Gussrohr DN 50|70|80|100|125|150|200 (cast iron pipe), KA-Rohr DN 50|70|100|125|150|200, KA-Rohr Form 2 DN 125|200|250, PE-Rohr DN 50 (PE pipe), ST-Rohr DN 100|125|150|200 (steel pipe).
Not every combination exists. Without UebergangAn the page shows all targets for UebergangVon.

Example: LORO-X DN 100 to cast iron pipe DN 100 (fitting 00630.100X): https://www.loro.de/service/online-konfigurator/uebergaenge?UebergangVon=LORO-X%20DN%20100&UebergangAn=Gussrohr%20DN%20100

7. Specification via hand-over link [works today] (single articles only)

When: The user wants to take articles into a bill of quantities (BoQ) and create e.g. GAEB, ÖNORM, PDF or Excel from it. The link puts the articles into the online specification in the user's browser. LORO stores something only when the user saves there. The user can export afterwards on that page.

Link pattern:

English: https://www.loro.de/en/service/online-specification?WKPlusArtikel1=<article no>&WKPlusArtikelMenge1=<quantity>&WKPlusArtikel2=<article no>&WKPlusArtikelMenge2=<quantity>…
German:  https://www.loro.de/service/online-ausschreibung?… (same parameters)

Items 1 to 50 (WKPlusArtikel1 … WKPlusArtikel50, each with WKPlusArtikelMenge<n>).
Article number: capital letters, digits, period, hyphen, at most 50 characters. Quantity: whole number from 1; if missing or 0, 1 applies.
All items end up in the first parts list.

Resolve LX systems into single parts first. The link accepts only single articles; an LX designation would be taken over as an unknown item. With the MCP tool build_tender_link (way 2) the server does the resolving. Without a connector:

Open the LX page (item 2), e.g. https://www.loro.de/en/product/LX772-4X/.
Take each part from the parts list with its quantity.
Multiply each quantity by the number of systems.
Form one item per part; add up identical parts from several systems.

It is often easier to use the link from item 2 (?AnzahlSysteme=<n>): the user clicks “in Ausschreibung” there.

Examples:

2 × LORO-X rectangular scupper 19041.000X: https://www.loro.de/en/service/online-specification?WKPlusArtikel1=19041.000X&WKPlusArtikelMenge1=2
4 × LX772-4X, resolved into 15 parts:

https://www.loro.de/en/service/online-specification?WKPlusArtikel1=13506.100X&WKPlusArtikelMenge1=4&WKPlusArtikel2=01385.000X&WKPlusArtikelMenge2=4&WKPlusArtikel3=01201.100X&WKPlusArtikelMenge3=8&WKPlusArtikel4=01203.050X&WKPlusArtikelMenge4=8&WKPlusArtikel5=13217.100X&WKPlusArtikelMenge5=4&WKPlusArtikel6=13500.100X&WKPlusArtikelMenge6=4&WKPlusArtikel7=01101.100X&WKPlusArtikelMenge7=4&WKPlusArtikel8=01108.050X&WKPlusArtikelMenge8=4&WKPlusArtikel9=13510.100X&WKPlusArtikelMenge9=4&WKPlusArtikel10=00911.100X&WKPlusArtikelMenge10=24&WKPlusArtikel11=00911.050X&WKPlusArtikelMenge11=20&WKPlusArtikel12=00975.100X&WKPlusArtikelMenge12=12&WKPlusArtikel13=00986.000X&WKPlusArtikelMenge13=4&WKPlusArtikel14=09604.200X&WKPlusArtikelMenge14=12&WKPlusArtikel15=13235.100X&WKPlusArtikelMenge15=4

8. Online calculation of flat roof drainage (DIN 1986-100)

When: The user wants to size the main and emergency drainage of a roof area.

Prefill the rainfall intensity [works today]

English: https://www.loro.de/en/service/online-calculation/flat-roof-drainage?r55=<r5,5>&r5100=<r5,100>
German:  https://www.loro.de/service/online-berechnung/flachdachentwaesserung?r55=…&r5100=…

Unit of the rainfall intensity: l/(s·ha), decimal point.
The link fills the two rainfall intensity fields. The user enters area, runoff coefficient and roof build-up on the page; there they calculate and receive the PDF.
Use it only with values the user gives or knows from loro.de.

Example: https://www.loro.de/en/service/online-calculation/flat-roof-drainage?r55=330&r5100=603.3 (KOSTRA values for postcode 30159 Hannover)

Without rainfall intensity: https://www.loro.de/en/service/online-calculation/flat-roof-drainage. The German page has a postcode search for the KOSTRA values there.

Finished calculation via link [works today]

With at least one partial-area parameter (e.g. a_1) the page prefills the form and calculates immediately. Result, drain suggestions and warnings are ready; the user checks them, creates the PDF or adds the drains to the specification. With only kostra_plz or r55/r5100 the rainfall intensities are prefilled; the calculation starts with a_1.

English: https://www.loro.de/en/service/online-calculation/flat-roof-drainage?r55=<r5,5>&r5100=<r5,100>&a_1=<m²>&c_1=<coefficient>&dachaufbau_1=<build-up>
German:  https://www.loro.de/service/online-berechnung/flachdachentwaesserung?kostra_plz=<postcode>&a_1=<m²>&c_1=<coefficient>

Project parameters:

Parameter	allowed values	Unit
`kostra_plz`	5-digit German postcode; sets r5,5 and r5,100 from KOSTRA-DWD-2020 and takes precedence over `r55`/`r5100`. Only on the German page (the other language pages only show a note), so on the English page use `r55` and `r5100`	–
`r55`	number > 0 (normal rainfall intensity r5,5)	l/(s·ha)
`r5100`	number > 0 (100-year rainfall intensity r5,100)	l/(s·ha)

Parameters per partial area (N = 1 to 30; several areas with a_2, c_2 etc.):

Parameter	allowed values	Unit
`a_N`	roof area, number > 0	m²
`c_N`	runoff coefficient `1`, `0.9`, `0.8`, `0.7`, `0.5`, `0.4`, `0.2`; another number > 0 up to 1 is taken as a manual coefficient	–
`dachaufbau_N`	`Warmdach` (warm roof), `Kaltdach` (cold roof), `Umkehrdach` (inverted roof), `WU-Beton` (waterproof concrete), or `-`	–
`schutz_N`	`1` = particularly worth protecting (emergency drainage with the full r5,100), `0` = no	–
`fassadenflaeche_N`	adjoining facade area, number ≥ 0	m²

There are further, rarely needed parameters per partial area (retention, water heights, choice of drains and their quantity, safety margin); they correspond to the fields of the form, see there.

Notes:

Numbers with a period or comma, without thousands separators and without sign.
Invalid values are not applied; the page names the parameter and the rule. Fields not given keep the tool defaults or the state of the user's session.
Free texts (project, designation, comment, e-mail) are not possible via link.
The result is a non-binding preliminary design (see rule 3). Rainfall intensity via kostra_plz applies to Germany only.

Example (English, two partial areas, second with facade area, first particularly worth protecting): https://www.loro.de/en/service/online-calculation/flat-roof-drainage?r55=280&r5100=520&a_1=900&c_1=0.4&schutz_1=1&a_2=300&c_2=1&fassadenflaeche_2=120

9. Contact persons [works today]

Germany: https://www.loro.de/en/contact or https://www.loro.de/kontakt. There the user finds the field and office sales contacts by postcode.
Other countries: https://www.loro.de/en/contact/international or https://www.loro.de/kontakt/international. On the language versions of loro.de the country representative is shown at the top of every page.

Examples

The links in these examples were retrieved once on 28.10.2026 (HTTP 200, expected content present). The example dialogues are translated from the German page; the links and numbers are the same, the German-language links are replaced by the English ones where an English page exists.

Example 1: Spare part in the trade

User: “A customer needs a replacement for a LORO rectangular scupper 300 × 100. Is there a data sheet and CAD for it?”
Assistant: “That is the LORO-X rectangular scupper 300 x 100 with adhesive flange made of stainless steel 1.4301, article number 19041.000X. On the product page you will find technical data, EAN, the data sheet, the product profile PDF and the CAD files (DXF, DWG, STEP, IFC): https://www.loro.de/en/product/19041.000X/
Prices are available from your LORO contact person.”

Example 2: Parapet main drainage

User: “Which LORO drains are there for a parapet, main drainage, free-surface flow, DN 100?”
Assistant: “With this preselection the LORO configurator shows the matching systems (currently 31): https://www.loro.de/en/service/online-configurator/flat-roof-drainage?entwaesserung=Attika&entwaesserungsart=1&stroemungsart=Freispiegel&nennweite=100
There you can filter further by flange and engagement depth. The selection is a non-binding preselection and must be checked by the responsible planner.”

Example 3: Emergency drainage on a concrete roof

User: “Flat roof, concrete slab with warm roof. I need emergency drainage DN 100.”
Assistant: “Here is the configurator with roof build-up ‘concrete, warm roof’, emergency drainage and DN 100 (currently 57 systems): https://www.loro.de/en/service/online-configurator/flat-roof-drainage?dachaufbau=BetonWarmdach&entwaesserungsart=2&nennweite=100
You can size the required discharge with the online calculation: https://www.loro.de/en/service/online-calculation/flat-roof-drainage. The result is a non-binding preliminary design.”

Example 4: Complete system into the specification

User: “I need the system LX772-4X four times in the bill of quantities.”
Assistant: “On this page the number of systems is already set to 4: https://www.loro.de/en/product/LX772-4X/?AnzahlSysteme=4
With “in Ausschreibung” the page takes over all 15 single parts, each with four times the quantity. In the online specification you can then create GAEB, ÖNORM, PDF or Excel.”

Example 5: Connection to KA pipe

User: “How do I connect a KA pipe DN 100 to LORO-X DN 100?”
Assistant: “For this LORO offers the transition piece 00750.100X with the sealing element 00933.100X: https://www.loro.de/service/online-konfigurator/uebergaenge?UebergangVon=KA-Rohr%20DN%20100&UebergangAn=LORO-X%20DN%20100 (German-language page)
For questions on the installation situation your LORO contact person will help.”
