Questions

Castos, answered

Is there a Castos MCP server?

APIANT's MCP server at https://mcp.apiant.ai works with Castos. 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 Castos actions on demand, or have APIANT build, test and run automations that use Castos. Nothing to install.

What can start an automation from Castos?

Any of Castos's 3 triggers in the catalog, including New Episode, New Podcast and New Private Subscriber. Describe the moment in plain language and your agent picks the right one.

What can your agent do in Castos?

Any of Castos's 18 actions, including Create Episode, Create Podcast, Create Private Subscriber and Update Episode. Your agent maps the data both ways and tests every scenario before it ships.

Can I use Castos directly from Claude, ChatGPT or Cursor?

Yes. Connect your AI client to APIANT once and it works with Castos two ways. Ask it to do something in Castos 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 Castos API?

No. APIANT connects to the Castos API for you, with your Castos API key. Describe what you want in plain language and your agent builds it on the Castos triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the Castos API documentation and adds it.

Which apps can Castos connect to?

Any app in the catalog; the list on this page pairs Castos 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.
