The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
add_document ~245

Uploads a file to a draft order: an energy bill or Heizkostenabrechnung (rechnung) or a photo (street side, heating, type plate). JPG, PNG, WebP or PDF as base64, at most 10 MB, 20 files per order. Bills are read and compared with the entered consumption after the customer has ordered; the Energieberater checks the photos. Usually the customer takes the photos on our page after the confirmation email. Orders nothing.

check_eligibility ~245

Checks whether Energieausweis Express can issue a Verbrauchsausweis (consumption-based energy certificate) for a residential building in Germany, before any order exists. Returns yes or no with the reason in German (including the rule for houses with a Bauantrag before 1 November 1977 and the change on 1 January 2027), the all-inclusive price, the delivery time and what is needed. Changes nothing.

find_building ~138

Finds the building at a German address in our 3D building data. Returns the building at the address first, then nearby buildings, each with a building_ref for start_order and a short German description (type, storeys, footprint). If several addresses match, returns them instead: ask the user which one is meant. Where the address may be one of several buildings (semi-detached or terraced houses, several buildings on one plot), ask the user which is theirs. Changes nothing.

request_confirmation ~327

Sends the customer one email with a link to their prepared order on our website. This does NOT order or charge anything: the customer checks the data there, adds what is missing (usually photos of the street side and the heating) and orders and pays on our page themselves. Before calling it, ask the user for permission and tell them the price review_order returned and that they will get an email, e.g. 'Soll ich das für <Preis> bei Energieausweis Express vorbereiten? Sie bekommen dann eine E-Mail, prüfen alles und bestellen selbst.' Needs the customer's name, the email address they gave for this order, and who orders. One email per order plus one resend (e.g. to a corrected address); the link is valid for 7 days. Afterwards tell the user to look for the email with the subject 'Ihr Energieausweis ist vorbereitet – bitte prüfen und bestellen', also in the spam folder.

start_order ~114

Starts a draft order for the building the user confirmed (building_ref from find_building). Orders and charges nothing. Returns order_id and order_token, which every later tool needs; the token opens only this order, so keep it private and never show it to anyone. Also returns what our 3D building model and the cadastre already say about the building (estimates the customer can correct) and the open points.

update_order ~247

Enters or corrects data of a draft order: facts about the building, the heating, and the consumption periods as printed on the bills, in the bill's unit (kWh; m3 of gas, with the bill's Brennwert and Zustandszahl; litres of oil; kg of pellets; we convert). The consumption is always the whole building's, also when the customer owns one flat: from a Heizkostenabrechnung take the Gesamtverbrauch der Liegenschaft, never the customer's own share. Send only what you know: fields left out stay as they are, and consumption.periods replaces all periods. Synonyms such as 'Gas' or 'heat pump' are accepted. Values are marked as entered by an assistant; the customer sees and confirms them before ordering. Returns the order as it is now and the open points. Orders nothing.

Install

How do I install the Energieausweis Express MCP server?

Energieausweis Express is a hosted endpoint at https://energieausweis-express.de/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.

Common questions

What is the Energieausweis Express MCP server?

Energieausweis Express is an MCP server listed in the public MCP registry as de.energieausweis-express/energieausweis. Prepare a German Energieausweis (energy certificate); an Energieberater checks and signs it. This page covers its hosted endpoint (https://energieausweis-express.de/mcp).

Is the Energieausweis Express MCP server safe to use?

Energieausweis Express scores 74 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 Energieausweis Express MCP server expose?

Energieausweis Express exposes 11 tools: add_document, answer_inquiry, check_eligibility, find_building, get_certificate, and 6 more. Their descriptions and schemas cost roughly 1,912 tokens of context every time the server is loaded.

Does the Energieausweis Express MCP server require authentication?

No. We connected to Energieausweis Express without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Energieausweis Express MCP server still maintained?
