Connect Le Chat (Mistral) to Aggregate

Last updated

Le Chat adds custom MCP servers as Connectors. Only an admin can add one; on Free, Pro and Student plans the account owner is the admin.

  1. In Le Chat, open Connectors and choose + Add Connector.
  2. On the Custom MCP Connector tab, enter Aggregate as the Connector name and https://app.aggregate.finance/mcp as the Server URL.
  3. Choose Connect. Le Chat detects that Aggregate uses sign-in (OAuth 2.1); sign in to Aggregate and choose what Le Chat can see.
  4. In a chat, turn the Aggregate connector on from the tools menu.
  5. Try: "Which customers are late paying us?"

Self-hosting? Use https://<your-server>/mcp instead; it must be reachable over HTTPS.

What it can do: read your cash, runway, transactions, invoices, payroll, cap table and reports, and (only if you allow it) add records, each one labeled and undoable for 30 days. It can never move money, pay bills or send anything.
