CycleCalcs computes astronomical event data for a given location and date. Callers can retrieve sunrise, sunset and twilight times, moonrise and moonset times, the current moon phase and illumination, planetary positions and visibility, upcoming solar and lunar eclipses, and the dates of equinoxes and solstices for a year. Results are returned as interpreted values rather than raw ephemeris tables. No credentials required. No account needed [cyclecalcs.com](https://cyclecalcs.com/) **8** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want to automate with CycleCalcs? Give your AI client this address. `https://mcp.apiant.ai` One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser. ### Set it up in your client ### Claude Code Run this in the directory you want to work in. `claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai` Start Claude Code there, approve the server, and sign in in the browser page it opens. [Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code) ### Claude, web and desktop Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Cursor Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Zed Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Codex and the ChatGPT desktop app Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in. [Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp) ### Any other MCP client Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

Action **Get planet positions** Returns all eight planets in one request: place, brightness, apparent size, retrograde state, next station, and whether each is worth observing tonight. - Action **Get rise and set times** Returns rise, transit, set, and lower-transit times for a named celestial object at a location/date, with explicit circumpolar/never-rises status. -

APIANT's MCP server at https://mcp.apiant.ai works with CycleCalcs. Add that address to any AI client that takes a remote MCP server and sign in once in your browser. Your client can then run CycleCalcs actions on demand, or have APIANT build, test and run automations that use CycleCalcs. Nothing to install. ### ### What can your agent do in CycleCalcs? Any of CycleCalcs's 8 actions, including Find places, Get angular separation, Get body positions and Get dark observing window. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can I use CycleCalcs directly from Claude, ChatGPT or Cursor? Yes. Connect your AI client to APIANT once and it works with CycleCalcs two ways. Ask it to do something in CycleCalcs once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running on its own. A one-off action uses your plan's tasks the same way an automation step does. ### ### Do I need to write code against the CycleCalcs API? No. APIANT connects to the CycleCalcs API for you. Describe what you want in plain language and your agent builds it on the CycleCalcs triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the CycleCalcs API documentation and adds it. ### ### Which apps can CycleCalcs connect to? Any app in the catalog; the list on this page pairs CycleCalcs with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
