Questions

Attestwire, answered

Is there a Attestwire MCP server?

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

What can your agent do in Attestwire?

Any of Attestwire's 5 actions, including Generate invoice XML, Get usage, Get validation record and Parse invoice. Your agent maps the data both ways and tests every scenario before it ships.

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

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

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

Which apps can Attestwire connect to?

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