Questions

Hjarni, answered

Is there a Hjarni MCP server?

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

What can start an automation from Hjarni?

Any of Hjarni's 1 trigger in the catalog, including New Note. Describe the moment in plain language and your agent picks the right one.

What can your agent do in Hjarni?

Any of Hjarni's 14 actions, including Create Folder, Create Note, Update folder and Update note. Your agent maps the data both ways and tests every scenario before it ships.

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

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

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

Which apps can Hjarni connect to?

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