AI Agent n8n Workflow: Answer French Company Registry Questions

Instant answers on French & European company registry questions—powered by an AI Agent in n8n

This n8n workflow builds a chat-based AI agent that answers questions about French (and multiple European) companies by querying Sirenic’s MCP tools over official registries. It understands your question, pulls only the needed registry data, and returns source-cited results—while maintaining conversation context across messages.

What this workflow does

• Receives your question via the n8n Chat trigger.
• Uses an OpenAI chat model to interpret intent and determine which Sirenic MCP registry tools to call.
• Queries Sirenic’s MCP server for up-to-date company information from sources such as INSEE Sirene, INPI, BODACC, sanctions lists, and multiple European company registers.
• Handles paid lookups safely: if a paid tool responds with a payment-required quote, the workflow returns the exact price and what the tool would provide—without attempting the paid call.
• Maintains context with memory so follow-up questions work naturally, while replying in your language using only tool-returned, source-cited results.

Use cases

• Ask: “What is the registration status and identifiers of a French company?” and get registry-backed answers.
• Verify a company against sanctions or official records for compliance workflows.
• Support sales/ops teams with quick, cited facts on French/EU entities—without manual registry searching.
• Reduce research time in SaaS onboarding, KYB, or due diligence prep (with citations).
