The Arcsecond.io MCP Server provides a unified natural language interface to the world's astronomical data. Connect your Arcsecond account to your AI agent to search for celestial objects, manage observatory data, and track observation night logs seamlessly.
Key Features
- Celestial Object Search — Search for stars, galaxies, planets, and more to retrieve official names, types, and precise coordinates (RA/Dec).
- Object Metadata — Access detailed astrophysical data, including visual magnitude and classifications for millions of objects.
- Observatory Management — List observing sites, telescopes, and instruments associated with your observatory subdomain.
- Data Tracking — Access datasets and night logs to monitor ongoing observations and historical data collections.
- Night Log Oversight — Retrieve detailed logs of observations and calibrations organized by local noon-to-noon cycles.
- Global Data Access — Interface with a vast network of astronomical databases through a single, consistent API.
Who is this for?
- Professional Astronomers — Quickly retrieve object coordinates and check observatory status without manual database queries.
- Amateur Stargazers — Search for interesting celestial targets and get detailed metadata for planning observation sessions.
- Data Scientists — Integrate astronomical data retrieval into automated research and analysis workflows.

Frequently asked questions
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.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
