Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Free AREI cable sizing, Synergrid C10/26 inverter check, LED strip calculator. No account.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
check_inverter_c10_26Checks whether a PV inverter, battery inverter or other power-generating unit (PGU) is on the Synergrid C10/26 list of devices homologated for connection to the Belgian grid. Returns the outcome (found, found_with_limitations, expired, not_found, brand), matching devices with hom
suggest_inverter_c10_26Typeahead for the Synergrid C10/26 list: given a partial brand or model name, returns matching brands with device counts or, once a brand is recognised, its homologated models. Use this to resolve an ambiguous device name before calling check_inverter_c10_26.
get_inverter_datasheetReturns manufacturer datasheet data for an inverter from the Synergrid C10/26 list: maximum DC voltage, MPPT count and range, current limits per MPPT, start voltage, maximum PV power, battery capability, optimizer architecture, links to the datasheet and installation manual, the
size_cable_areiCalculates the required copper or aluminium cable cross-section for a residential circuit under the Belgian AREI/RGIE: design current, voltage drop per cross-section, protection check against the breaker rating and the recommended cross-section. Provide the load (A, W, kW or kVA)
calculate_led_stripCalculates power, current (total and per channel), required feed points, power-supply size and the extra-low-voltage feed cable for an analogue LED strip (5/12/24/48 V DC; single colour, CCT, RGB, RGBW, RGB+CCT). Provide the strip length in metres and either a preset or the datas
search_help_guidesSearches the PlanElec guides about getting started, automatic planning, document exports, AREI self-check coverage, floor plan import, symbols and circuits in the visitor’s current language. Returns up to five guides with title, summary, category and a link to the full article; t
search_regelwerkSearches Book 1 of the Belgian AREI/RGIE (Royal Decree on electrical installations) in the language of the text: Dutch, French or German; English uses the German text. Returns up to ten articles with number, title, an excerpt, the edition in force today and a link to the article
get_regelwerk_articleReturns the text of one article of Book 1 of the Belgian AREI/RGIE by its number (for example 4.2.4.3 or "AREI 7.1.4.3"), in the language of the text (Dutch, French or German; English uses the German text), with the edition, change notices of amending decrees, the titles of its s

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (0.2.0) reached the registry yesterday.
