Who it is for
Employees of an organisation already running Aerion who track time or approve entries from others.
Aerion
Project, time tracking, and approval records in chat
Overview
What Aerion does
Aerion is the ChatGPT connector for the project and time tracking system of the same name, published by CoffeeCup GmbH. Signed in users can look up records, read out what a given record contains, and ask about project, staffing, approval, and analytics data.
Writing is possible as well as reading. Records can be created or updated, personal time entries submitted, and approval steps carried out, but each of those is bounded by the permissions the account already holds in Aerion. The connector does not widen what a person is allowed to do.
The record gives no sample prompts and does not describe reporting output or exports.
What stands out
It can write as well as read, with every action limited by the permissions the account holds in Aerion.

Where Aerion is listed
Aerion ships this on both marketplaces: Aerion is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing
In the Claude connectors directory
Aerion publishes 12 tools to Claude. That is a mid-sized surface: 51.4% of the 1,253 Claude-listed connectors expose fewer.
That is exactly the median for Claude-listed connectors under Productivity, where 462 publish counts and 12 is the middle of the distribution.
It falls in the 11-20 tools band, which holds 22.5% of the Claude directory.
Aerion publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Aerion is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
In the publisher's words
How Aerion describes it
Aerion helps authenticated users inspect their project, time tracking, staffing, approval, and analytics data from Claude. Users can find and describe Aerion records, create or update permitted records, submit their own time entries, and perform approval workflows when their Aerion permissions allow it.
