Questions

UK Companies House, answered

Is there a UK Companies House MCP server?

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

What can your agent do in UK Companies House?

Any of UK Companies House's 12 actions, including Find companies by name, Find companies with advanced search, Find officers by name and Get company insolvency. Your agent maps the data both ways and tests every scenario before it ships.

Can I use UK Companies House directly from Claude, ChatGPT or Cursor?

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

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

Which apps can UK Companies House connect to?

Any app in the catalog; the list on this page pairs UK Companies House 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.
