Questions

Invoice Ninja, answered

Is there a Invoice Ninja MCP server?

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

What can start an automation from Invoice Ninja?

Any of Invoice Ninja's 1 trigger in the catalog, including New expense. Describe the moment in plain language and your agent picks the right one.

What can your agent do in Invoice Ninja?

Any of Invoice Ninja's 10 actions, including Email Invoice, Email Quote, Find Client and Find Credit. Your agent maps the data both ways and tests every scenario before it ships.

Can I use Invoice Ninja directly from Claude, ChatGPT or Cursor?

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

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

Which apps can Invoice Ninja connect to?

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