Questions

Payaca, answered

Is there a Payaca MCP server?

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

What can your agent do in Payaca?

Any of Payaca's 14 actions, including Update project, Update scheduled event, Add invoice and Add payment. Your agent maps the data both ways and tests every scenario before it ships.

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

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

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

Which apps can Payaca connect to?

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