Reviews ## What our customers say Questions ## Quaderno, answered ### ### Is there a Quaderno MCP server? APIANT's MCP server at https://mcp.apiant.ai works with Quaderno. 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 Quaderno actions on demand, or have APIANT build, test and run automations that use Quaderno. Nothing to install. ### ### What can start an automation from Quaderno? Any of Quaderno's 3 triggers in the catalog, including New Contact, New Invoice and New Sale. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Quaderno? Any of Quaderno's 24 actions, including Create Contact, Create Estimate, Create Expense and Create Invoice. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can I use Quaderno directly from Claude, ChatGPT or Cursor? Yes. Connect your AI client to APIANT once and it works with Quaderno two ways. Ask it to do something in Quaderno 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 Quaderno API? No. APIANT connects to the Quaderno API for you, with your Quaderno API key. Describe what you want in plain language and your agent builds it on the Quaderno triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the Quaderno API documentation and adds it. ### ### Which apps can Quaderno connect to? Any app in the catalog; the list on this page pairs Quaderno 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.
