Overview

Description from the maker (original English)

Read refrigeration units, service history, F-gas logs and alarms in Maci. Read only.

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: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

The server asks you to sign in before it lists its tools.

Compared with others in Otheri

  • More stars than 0% of the other 32718 servers in this category
  • Published to the registry more recently than 82% of the other 32718 servers in this category
  • Basic checks equal to or better than 100% of the other 32718 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Maci safe?

It passed 3 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 (1.0.0) reached the registry 7 days ago.

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?

Maci for AI assistants (MCP)

Connect Maci to an assistant that speaks the Model Context Protocol and ask about your refrigeration units in your own words:

  • Which of our units are due a leak check in November?
  • Are there open alarms at the Vesterbro store, and has anyone taken them?
  • When was MC-0482 last serviced, and what was done?
https://mcp.maci.energy/mcp

The server is read only. It reads through Maci's API, so the assistant sees what your organisation may see in Maci and nothing more, and every tool call counts as an API call. The full guide is at api.maci.energy/docs/ai-assistants.

Connect

Claude (claude.ai and the desktop app): Settings → Connectors → Add custom connector. Name it Maci, paste the address above and choose Connect.

ChatGPT: Settings → Connectors, add a custom connector with the address above. (ChatGPT may ask you to turn on developer mode for custom connectors.)

Claude Code:

claude mcp add --transport http maci https://mcp.maci.energy/mcp

Then run /mcp in Claude Code and choose Maci to log in.

Cursor, VS Code and others: see clients.md.

In each case the assistant sends you to Maci. Log in as always, choose the organisation and say yes with your passkey. Only an organisation's admin can connect it.

Skills

Instructions that walk the assistant through a task, step by step. Give one to the assistant (in Claude: add it as a skill, or paste it into the conversation) and ask for the task.

SkillWhat it does
Leak check planThe units due a leak check in a period, by site, with the overdue ones first
F-gas overviewRefrigerant, charge and CO2 equivalent by site, and the units without a leak check status
Alarm reportA period's alarms: how many, how fast they were taken, how many were false
Before a visitWhat a technician should know before going to a unit

More examples of questions: prompts.md.

Your data

The assistant reads only, and only what your organisation may see. What it reads goes to the assistant you chose and its provider, so connect only an assistant your organisation is allowed to use. Each connection is listed in the app under Konto → API-nøgler, "Forbundne AI-assistenter", with who made it and when it was last used. Removing it stops it at once, and a connection that is not used for 30 days ends by itself.

For developers

The server follows the MCP specification of 2026-07-28: Streamable HTTP, OAuth 2.1 with PKCE (S256), Client ID Metadata Documents and dynamic client registration, with app.maci.energy as the authorization server. Details in the guide.
