Reviews ## What our customers say Questions ## CLOSUM, answered ### ### Is there a CLOSUM MCP server? APIANT's MCP server at https://mcp.apiant.ai works with CLOSUM. 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 CLOSUM actions on demand, or have APIANT build, test and run automations that use CLOSUM. Nothing to install. ### ### What can start an automation from CLOSUM? Any of CLOSUM's 1 trigger in the catalog, including New Lead. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in CLOSUM? Any of CLOSUM's 3 actions, including Add Lead, Get lead and List leads. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can I use CLOSUM directly from Claude, ChatGPT or Cursor? Yes. Connect your AI client to APIANT once and it works with CLOSUM two ways. Ask it to do something in CLOSUM 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 CLOSUM API? No. APIANT connects to the CLOSUM API for you, with your CLOSUM API key. Describe what you want in plain language and your agent builds it on the CLOSUM triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the CLOSUM API documentation and adds it. ### ### Which apps can CLOSUM connect to? Any app in the catalog; the list on this page pairs CLOSUM 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.
