What is the Arcsecond.io MCP Server?
The Arcsecond.io MCP Server gives AI agents like Claude, ChatGPT, and Cursor direct access to Arcsecond.io via 7 tools. Access astronomical data and manage observatories with Arcsecond.io — search objects and track night logs via AI. Powered by the Vinkius - no API keys, no infrastructure, connect in under 2 minutes.
Built-in capabilities (7)
Tools for your AI Agents to operate Arcsecond.io
Ask your AI agent "Search for the 'Andromeda Galaxy' and get its coordinates." and get the answer without opening a single dashboard. With 7 tools connected to real Arcsecond.io data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.
Why teams choose Vinkius
One subscription gives you access to thousands of MCP servers - and you can deploy your own to the Vinkius Edge. Your AI agents only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure and security, zero maintenance.

Frequently asked questions about the Arcsecond.io MCP Server
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 tool allows you to search across millions of objects in the SIMBAD, Gaia, and other astronomical databases integrated into Arcsecond.io.
