Questions

Tax ID Pro, answered

Is there a Tax ID Pro MCP server?

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

What can your agent do in Tax ID Pro?

Any of Tax ID Pro's 3 actions, including List formats, Validate tax ID and Validate tax IDs in batch. Your agent maps the data both ways and tests every scenario before it ships.

Can I use Tax ID Pro directly from Claude, ChatGPT or Cursor?

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

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

Which apps can Tax ID Pro connect to?

Any app in the catalog; the list on this page pairs Tax ID Pro 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.
