- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 61/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 5586 tokens (~253/item across 22 items; 22 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 99/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 97% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 22 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 23 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `plan_roof` (~826 tokens)

Plan a roof (solar roof check)

Plan solar modules on a house's roof from the Bavarian 3D building model, the aerial photo and the laser scan, exactly as Sky Solar's solar roof check page does: modules, kWp, kWh a year with measured weather, shade loss and self-use with and without a battery, each roof face with tilt and direction, the obstacles found, money a year at public rates (own use and feed-in) for a choice of battery sizes (none, or 4 to 20 kWh; any whole kWh in between on request), the municipal subsidy and, with an offer price, the payback, kWh month by month and per face, the worst shade casters, questions about unsure spots for the person and what else to ask them, notes on likely model errors, and a solar roof check link that opens this plan in 3D for the person to check, change and send an enquiry from. On a new plan (house) where the aerial photo speaks against the roof's outline, the AI outline check runs by itself, as on the page: "applied" says what it changed. A link is read as it is; "notes" says when the outline may still be wrong. Give house (from find_house) for a new plan, or link to read and explain a plan the person already has. Pass the person's answers to the questions with answers. Works outside Sky Solar's service area too and says so. An example, not a quote; no prices.

Input parameters:

- `ev` (boolean): An electric car is (or will be) charged at home: by default 15,000 km a year, about 2,955 kWh, charged in the evening (edit_roof device sets km, when and how fast).
- `geometry` (boolean): true: add a complete geometry snapshot to the answer (the default stays short): for every face and dormer roof its outline, size, usable box and the eave and slope axes (with compass bearings), every…
- `heat_pump` (boolean): A heat pump heats the house: by default about 4,500 kWh a year, mostly in winter (edit_roof device sets the person's own figure).
- `house` (string): The house id from find_house ("musterhaus" is the example house).
- `link` (string): A solar roof check link (https://pv.skysolar.de/dachcheck/#d=…), as plan_roof, edit_roof or the solar roof check page gave it.
- `offer_eur` (number): The total price on an offer the person already has, euros before any subsidy (0 clears it): the solar roof check link then shows the payback. Never a price of Sky Solar's.

### `edit_roof` (~855 tokens)

Improve a roof plan (solar roof check)

Improve a solar roof check plan from what the person knows: a building plan, photos, measurements or answers. Read the numbers yourself (tilt, overhang, sizes, where a chimney is) and pass them as edits: slope (tilt and direction of a face), overhang (move an eave or end in or out), split a face, remove or restore a face, add_face (an extension or garage against a wall), add, remove or confirm obstacles (with height_m), change_kind (e.g. a found dormer to a flat-roofed or hipped one, or a chimney to a vent), colour (sheet metal, window frames, …), covering (tiles, Falzblech, Trapezblech, rack tilt 5/10/15°, flat-roof racks; on a flat dormer roof it decides racks or flush), dormer_modules, fill_dormer and clear_dormer (one dormer's roof full of modules, or none), modules (arrangement as the page names it: „Ästhetisch“ design, „Ordentlich“ tidy, „Maximal“ most; orientation incl. mixed; module type), add_part or remove_part (an attached building part from "building_parts", e.g. the other half of a semi-detached house), remove_tree, restore_tree or tree_height (trees from "shade", the worst shade casters first), edit_obstacle (move, resize, raise, turn or give a free four-cornered outline to any obstacle, found or own), face_outline (any outline by corners, as the editor drags them), reset_face („Wie gemessen“), unsplit, add_face also with corners_m (any shape), drawn_face (eave height) and delete_face, turn_racks (flat roofs and racked dormer roofs), find_similar („Ähnliche finden“ on the aerial photo), check_outline (the AI outline check), search_again, module fields by hand (lay_by_hand, add_modules as a block of rows and columns, remove_modules, move_field, turn_field; also on dormer roofs from "dormer_roofs"; on flat roofs the modules keep standing on their racks), the modules in an area together as the page selects them (move_modules, turn_modules, set_module_type for a module type of their own; remove_modules takes an area too) and household (incl. offer_eur, th…

### `compare_plans` (~474 tokens)

Compare roof plan variants (solar roof check)

Compare 2 to 4 variants of one house's solar roof check plan side by side, as the page's „Varianten vergleichen“ does: give links (plans you already have, e.g. from edit_roof), or link and variants, each the plan with a few edit_roof edits (a battery size or none, a roof face off or on, an e-car or a heat pump, an offer price). Answers a table with, per plan: modules, kWp, kWh a year with measured weather, own use (share of the roof's power used in the house), autarky, self-used, fed-in and grid kWh, days without the grid, euros a year at public rates, kWh by month, the payback only with the price of the person's own offer, its link, and the difference to the first plan; plus the first plan's battery curve: what each further kWh of battery adds a year, and from about which size each kWh adds little; and `day_views`: the same three real days of the person's weather (sunny, cloudy, winter) for every plan, hour by hour (solar, consumption, from the sun, to and from the battery, to and from the grid), the page's day view. Appliances and a heating rod are variants too (edit_roof device). One weather fetch for all. Nothing is stored; each variant comes back as its own link. An example, not a quote; no prices.

Input parameters:

- `link` (string): One plan to compare variants of (with variants).
- `links` (array): 2 to 4 solar roof check links of the same house; the first is the one the others are compared with (usually the person's plan).
- `variants` (array): 1 to 3 variants of the plan in link, each the plan with a few edits: a battery size (household battery_kwh, 0 for none) or type (household battery_type), a face off or on (remove_face, restore_face),…

### `roof_report_pdf` (~234 tokens)

Roof plan as a PDF (solar roof check)

The plan behind a solar roof check link as the one-page PDF report the solar roof check page prints, in German, for the person to keep or print: the 3D picture, key figures, the roof from above with its modules, the faces, kWh month by month, self-use with and without battery, the worst shade casters, and a QR code that opens the plan. The PDF comes back inside this answer as an embedded resource (application/pdf, base64); save it as a file. Nothing is stored on the server and no download link is made. This one-shot call waits at most 55 seconds for the page's own report and otherwise answers with a drawn version (same modules; the answer's page_report says why and where the time went); for the page's own report with more time use roof_report_pdf_start. An example, not a quote; no prices.

Input parameters:

- `link` (string, required): A solar roof check link (https://pv.skysolar.de/dachcheck/#d=…), as plan_roof, edit_roof or the solar roof check page gave it.

### `roof_report_pdf_start` (~187 tokens)

Start the roof plan PDF as a job (solar roof check)

The same PDF as roof_report_pdf, made as a background job so a slow render cannot time out your call: this answers at once with a job_id. The page's own report with its 3D picture takes 30 to 150 seconds to draw on the server. Then call roof_report_pdf_status with the job_id every 10 seconds until it says done (or failed, with the reason), and roof_report_pdf_file to get the file. If the page's report cannot be made in time you get the drawn version, and the status says so. The finished PDF is kept for 15 minutes under the random job_id; nothing else is stored.

Input parameters:

- `link` (string, required): A solar roof check link (https://pv.skysolar.de/dachcheck/#d=…), as plan_roof, edit_roof or the solar roof check page gave it.

### `roof_report_pdf_status` (~93 tokens)

Status of a roof plan PDF job (solar roof check)

Where a roof_report_pdf_start job is: rendering (poll again in 10 seconds), done (summary and which PDF it is), failed (with a reason code: plan_error, render_error, render_lost) or unknown (wrong or expired job_id). A tool error here means the call itself failed, not the job.

Input parameters:

- `job_id` (string, required): The job_id roof_report_pdf_start gave.

### `roof_report_pdf_file` (~64 tokens)

Get the finished roof plan PDF (solar roof check)

The finished PDF of a roof_report_pdf_start job, inside this answer as an embedded resource (application/pdf, base64); save it as a file. Only when the status says done.

Input parameters:

- `job_id` (string, required): The job_id roof_report_pdf_start gave.

### `roof_picture_start` (~532 tokens)

Start a 3D picture of the plan (solar roof check)

An image (PNG, or JPEG when large) of the plan behind a solar roof check link, drawn by the solar roof check page itself in 3D, from a fixed, named view: front (the start view the page opens with, three-quarters from above), above (straight down, north up), north, east, south or west (from that side, 35° up, about square on to a roof face), or sun (the roof's sun map, "Sonnendach", from above). The same plan and view give the same picture (within a calendar year, while the map data stays the same): the camera follows the house, the sun stands at 21 June, 13:00, nothing moves, no cat and no editing marks, the plan's fine print as on the page. So variants of a plan compare side by side, which screenshots of the page do not (its view moves). Size up to 1600 × 1000 pixels (default). Answers at once with a job_id: the server draws the 3D in software, which takes 30 to 150 seconds. Then call roof_picture_status every 10 seconds until done, and roof_picture_file to get the picture (a JPEG instead of a PNG when the PNG would be over about 1.4 MB). The picture is kept for 15 minutes under the random job_id; nothing else is stored.

Input parameters:

- `height` (integer): Height in pixels, 400 to 1000 (default 1000).
- `link` (string, required): A solar roof check link (https://pv.skysolar.de/dachcheck/#d=…), as plan_roof, edit_roof or the solar roof check page gave it.

- `width` (integer): Width in pixels, 640 to 1600 (default 1600).

### `roof_picture_status` (~92 tokens)

Status of a 3D picture job (solar roof check)

Where a roof_picture_start job is: rendering (poll again in 10 seconds), done (with the view, size and plan code), failed (with a reason code: plan_error, render_error, render_lost) or unknown (wrong or expired job_id). A tool error here means the call itself failed, not the job.

Input parameters:

- `job_id` (string, required): The job_id roof_picture_start gave.

### `roof_picture_file` (~136 tokens)

Get the finished 3D picture (solar roof check)

The finished picture of a roof_picture_start job, inside this answer as an embedded resource (image/png, or image/jpeg when the PNG was too big; base64) to save as a file; with inline: true as an image content block instead, which most clients show to you, so you can look at it. Only when the status says done.

Input parameters:

- `inline` (boolean): true: the picture as an image content block (image/png or image/jpeg), which most clients show to you, instead of an embedded resource to save as a file.
- `job_id` (string, required): The job_id roof_picture_start gave.

### `sun_tomorrow` (~164 tokens)

Tomorrow's sun on the roof (solar roof check)

What the plan behind a solar roof check link will make tomorrow, from the German Weather Service forecast (Bright Sky): expected kWh and the peak, hour by hour, against what a clear sky would give, sunrise and sunset, and the best stretch of the day to run the dishwasher or charge the car slowly from the roof's own power (with how much of the job the roof covers then). A forecast, cached ten minutes; the plan is read from the link, nothing is stored. Takes the link from plan_roof or edit_roof.

Input parameters:

- `link` (string, required): A solar roof check link (https://pv.skysolar.de/dachcheck/#d=…), as plan_roof, edit_roof or the solar roof check page gave it.

### `consultation_link` (~54 tokens)

How to request a consultation

The form and phone numbers for a free first consultation. The person sends the enquiry themselves; this server cannot book or send anything.

Input parameters:

- `locale` (string): Language of the answer: de (German) or en (English).
