Perplexity

Instant Business Identity Verification

Run `autocomplete_identity` to pull legal business data into your chat. Stop guessing entity names and get the exact state records you need for compliance. Your AI client processes these records in seconds. It pulls details directly from Secretary of State databases so you don't have to navigate public portals.

Automated Tax and Document Retrieval

Use `list_tax_registrations` to check if a business is compliant without leaving your workspace. This MCP Server maps out the full tax profile for any entity. Need specific filings? Call `get_document` to pull the actual PDF or record data. You get the evidence you need inside your Claude Desktop session.

Streamlined Onboarding Flows

Execute `prefill_business` to populate your internal forms with validated company data. This removes the manual entry step that causes most onboarding drop-offs. Your agent handles the `create_business` calls to initiate new verification workflows. It keeps your pipeline moving without manual oversight.
