One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Questions

Quadratic, answered

Is there a Quadratic MCP server?

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

What can your agent do in Quadratic?

Any of Quadratic's 8 actions, including Update cells, Update code cell, Add file and Get cells. Your agent maps the data both ways and tests every scenario before it ships.

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

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

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

Which apps can Quadratic connect to?

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