Reviews ## What our customers say Questions ## Stax, answered ### ### Is there a Stax MCP server? APIANT's MCP server at https://mcp.apiant.ai works with Stax. 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 Stax actions on demand, or have APIANT build, test and run automations that use Stax. Nothing to install. ### ### What can start an automation from Stax? Any of Stax's 1 trigger in the catalog, including List Payment. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Stax? Any of Stax's 17 actions, including Create Customer, Create Item, Create Scheduled Invoice and Update customer. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can I use Stax directly from Claude, ChatGPT or Cursor? Yes. Connect your AI client to APIANT once and it works with Stax two ways. Ask it to do something in Stax 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 Stax API? No. APIANT connects to the Stax API for you, with your Stax API key. Describe what you want in plain language and your agent builds it on the Stax triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the Stax API documentation and adds it. ### ### Which apps can Stax connect to? Any app in the catalog; the list on this page pairs Stax 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.
