Key Capabilities
Stream French Corporate Lookups to React
Stop making your users stare at static loading spinners while fetching foreign corporate registries. Let your Vercel AI SDK application call `search_french_companies` and stream live matching results directly into your React components. When an analyst types a partial name, the UI renders live suggestions via `get_search_suggestions` on the fly. This keeps the interaction fast and interactive, running entirely within your Edge Functions without blocking the main thread.
Live Financial Data Rendering
Pulling raw balance sheets is usually a slow, clunky process that hurts user retention. This setup lets your Vercel AI SDK UI stream structured financial metrics using `get_company_financials` directly into your custom tailwind tables as the data arrives. You don't have to wait for the entire JSON payload to download before showing the numbers. Your users watch their dashboard build itself in real-time as the Pappers MCP Server pumps balance sheets and income statements straight to the client.
Instant PDF Fetching via Pappers MCP Server
Accessing official corporate articles of association shouldn't require a manual download flow. Your Vercel AI SDK agent can trigger `get_company_document` to pull the raw PDF bytes of French corporate filings directly into an inline viewer. This integration bypasses slow backend queues by letting your edge-rendered UI request legal files on demand. The Pappers MCP Server handles the raw registry handshakes, handing the documents straight to your client-side download handler.
