Perplexity

Search the entire sky from your chat

The `search_objects` tool connects Claude to the Arcsecond.io catalog. Ask a direct question like, "find all planetary nebulae in the constellation Orion," and you'll get a list back, right in your chat. It's faster than digging through a web UI. Once you have an object's ID, use `get_object` to pull its full profile. You get coordinates, object type, apparent magnitude—all the key details. This is the quickest way to get specific astronomical data for research or curiosity.

Check your observatory's status

If you run an observatory on Arcsecond.io, you can now manage it with your AI client. Use tools like `list_telescopes` and `list_observing_sites` to get a quick inventory of your equipment. It's a simple way to confirm what you have registered. For daily operations, the `list_night_logs` tool gives you a summary of recent observation sessions. You can even check on available image collections with `list_datasets`. This MCP server lets you ask your agent for a status report instead of logging into another dashboard.

Works with your Claude Desktop setup

This Arcsecond.io integration works the way you do. If you're using the native Claude Desktop app, you can run the MCP server locally for the lowest possible latency. It's ideal for developers who want to keep everything on their own machine. Using Claude on the web? Just paste the server URL into your custom connectors. You get the same tools for querying astronomical data, with zero installation. As long as your agent can reach the server, you're good to go.

Common questions about Arcsecond.io MCP in Claude Desktop

Just ask Claude directly. For example, type: "@tools search_objects name='Andromeda Galaxy'". The agent will use the Arcsecond.io tool and return the search results right in your conversation.

Yes. After you've configured the server, just ask your agent, "@tools list_night_logs for my main observatory." It will pull the recent log entries from your Arcsecond.io account.

The desktop app lets you run the MCP server locally for maximum speed and privacy. The web UI connects to a remote server URL, which requires no local setup but means your data transits the web.

You can use the `get_account_check` tool. It's a simple command to confirm that your agent can successfully communicate with the Arcsecond.io API through the server.

This server only accesses the Arcsecond.io data needed to run the specific tool you invoke. It handles authentication tokens but doesn't store your observatory data or search history. All operations are ephemeral.
