Why people use Arcsecond.io
Arcsecond.io for Managing Observatory Data
This Connector puts all that data into your AI client. You can just ask for the last night's logs or a list of all your observing sites, and the agent pulls it instantly. You get a unified view of your observatory without the tab-switching.
What Vinkius changes
You get instant access to astronomical data without leaving your chat interface.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about Arcsecond.io.
The practical details behind the request, access and result.
What can I do with the Arcsecond.io MCP?
You can use it to search for celestial objects, get precise coordinates, and manage your observatory's data. It lets your AI agent act as a research assistant for astronomical data.
Can I use Arcsecond.io MCP to find star coordinates?
Yes. You can ask your agent to find specific stars, planets, or galaxies, and it will return their RA and Dec coordinates instantly.
How does Arcsecond.io MCP help with observatory management?
It lets you list your observing sites, telescopes, and instruments. You can also check your datasets and historical logs to keep your operations organized.
Does Arcsecond.io MCP work for amateur stargazers?
Absolutely. It's great for planning observation sessions by retrieving metadata like visual magnitude and object types for any target in the sky.
Can I see my past observation logs with Arcsecond.io MCP?
Yes. The Connector can retrieve detailed logs of your observations and calibrations, organized by your local noon-to-noon cycles.
How do I connect Arcsecond.io MCP to my AI client?
You can connect it through the Vinkius catalog. Once connected, your AI client can access all the astronomical capabilities in one place.
How do I get my Arcsecond.io API Key?
Log in to your Arcsecond.io account and go to your Profile page. You will find your Personal API Key there.
What is an observatory subdomain?
If you are part of a specific observatory or organization on Arcsecond.io, your data is hosted on a subdomain (e.g., myobs.arcsecond.io). You can use this subdomain to access site-specific data.
Can I search for any astronomical object?
Yes, the search_objects capability allows you to search across millions of objects in the SIMBAD, Gaia, and other astronomical databases integrated into Arcsecond.io.
