PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 2 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 8 things (tools) check_inverter_c10_26, suggest_inverter_c10_26, get_inverter_datasheet, size_cable_arei …
  • The registry lists no key to fill in.

What it can do

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_26

    Checks 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_26

    Typeahead 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_datasheet

    Returns 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_arei

    Calculates 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_strip

    Calculates 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_guides

    Searches 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_regelwerk

    Searches 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_article

    Returns 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

Common questions

Is PlanElec Calculators safe?

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.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

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.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Zendesk
