Compliance checks shouldn't feel like detective work.

Today, verifying a company’s identity is a mess. You start with the corporate website, which gives you a name. Then you have to open State A's Secretary of State portal and manually search for filings. If that doesn't work, you move to State B, then maybe the IRS site to check tax status. It's hours of clicking through different portals and copy-pasting IDs into forms just to establish basic legitimacy.

With this MCP, that entire sequence vanishes. You give your agent a simple prompt. The system handles the routing: it checks the corporate records, pulls necessary filings from multiple states, and compiles everything for you in one clean response. You get verified, actionable data instantly.

Middesk MCP Provides Verified Business Identity Data

You no longer have to copy-paste a name into three different state websites just to confirm incorporation status. The agent can use the `get_business` tool, which pulls verified data from multiple sources simultaneously.

The result is immediate confirmation of legitimacy and compliance across jurisdictions. You stop wasting time on redundant manual checks and start making decisions with certainty.

What Middesk MCP does for your AI

This MCP gives your agent the ability to handle complex identity checks for businesses. You can start by asking it to populate core business data just from an EIN or a website address. Need to know if a company is properly registered? It retrieves official Secretary of State filings and documents, so you don't have to check multiple state websites.

The system also lets you manage tax registrations and track payroll compliance across states. When the information is complex, linking up through Vinkius makes it easy; your agent gets access to all these tools in one place. You can monitor verification requests live or search for businesses using suggestions based on existing SOS records.

Frequently asked questions about Middesk MCP

Does the Middesk MCP verify private business information? +

No, this MCP only accesses official public records like those maintained by Secretary of State offices. It won't provide internal financial data or non-public employee info.

How do I use the `autocomplete_identity` tool with Middesk MCP? +

To use it, just ask your agent to autocomplete an identity using a partial detail like a website. The tool returns live suggestions based on existing Secretary of State records.

Can I check tax compliance for multiple states using the Middesk MCP? +

Yes. You can use list_tax_registrations to find all known state registrations, then confirm specific statuses with get_tax_registration.

What if I don't know the company ID for a business? +

You can start by using prefill_business. Providing an EIN or website will often allow the system to look up and confirm core details without needing the specific internal ID.
