Perplexity

Run instant KYB checks with this MCP Server

Verify corporate identities using the `get_business` tool directly from your command line. Claude Code queries the Middesk database, pulls the registration status, and pipes the JSON output to your terminal tools for instant review. This MCP Server integration eliminates the need to open a browser or log into a web dashboard to check a merchant's status. You run one command, and the terminal agent returns the exact entity details.

Audit tax registrations via CLI

Inspect state tax accounts using the `get_tax_registration` tool during automated compliance checks. Claude Code fetches the active status of any business tax ID and prints the validation metrics to your shell. By running `list_tax_registrations`, your terminal agent can compile verification reports for batch processing jobs. This makes it easy to audit thousands of merchant tax records in a single cron run.

Fetch official Secretary of State files

Download official corporate filings using the `get_document` tool without leaving your terminal session. Claude Code extracts the document URL, verifies the filing date, and saves the metadata to your local workspace. The agent uses `list_documents` to verify that a business has submitted its annual reports. This gives you a fast, reliable way to audit corporate compliance status during high-volume reviews.
