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. ## Tools ### autocomplete_identity Suggests complete business identities based on partial information you provide. ### create_business Initiates a new, monitored request to verify an entire business entity using its legal name. ### get_business Retrieves all available public and official records for a specific, known company ID. ### get_document Fetches the content of one specific corporate filing or document by its unique identifier. ### get_tax_registration Retrieves all compliance details for a single state tax registration number. ### list_businesses Searches and returns lists of multiple businesses based on general criteria you specify. ### list_documents Returns a list of all available official documents associated with a specific business ID. ### list_tax_registrations Lists all state tax registrations linked to a particular corporate entity. ### prefill_business Quickly populates common business details when you provide an identifier, like a website or EIN. ## Prompt Examples **Prompt:** ``` Verify the business 'Acme Corp' located in Delaware. ``` **Response:** ``` Initiating verification for Acme Corp...

The M&A team needs to validate the target company's legal standing. They ask their agent to use `list_documents` and `get_document` on the primary business ID, instantly retrieving all articles of incorporation and annual reports needed for the pitchbook. ### Onboarding a new vendor from another state. The procurement officer needs to know if the vendor is compliant everywhere. They use `list_tax_registrations` to check all known states, ensuring tax compliance before signing any purchase order. ### Investigating a suspicious business name online. Instead of searching Google for conflicting addresses, the user asks their agent to use `autocomplete_identity`. The MCP provides live, accurate suggestions based on official Secretary of State records immediately. ### Validating a client's primary corporate identity. The sales team receives an EIN and needs basic facts. They ask the agent to run `prefill_business`, which quickly pulls verified legal names, addresses, and other core details, allowing the pitch to move forward immediately. ## Benefits - Instead of manually checking state websites for documents, this MCP lets your agent retrieve official Secretary of State filings instantly using the `get_document` tool. You get verified history in seconds. - When onboarding a client, you can use `prefill_business` to populate basic details from just one identifier. This saves hours of copy-pasting and initial data gathering. - Compliance checks are simpler. Use `list_tax_registrations` to see every state tax registration tied to an entity in one API call, instead of running multiple searches. - You can monitor the full lifecycle of a check. Start with `create_business`, which kicks off a request you then track until it's fully verified, providing clear status updates. - Need to find an unknown company? Use `autocomplete_identity` first. This provides live suggestions based on SOS data, guiding your investigation before you even know the full name. ## How It Works The bottom line is that you stop hopping between compliance tools and run all your KYC checks in one place. 1.
