Connect Mistral Le Chat to Crane Ledger

Mistral’s Le Chat supports custom MCP connectors (including on free plans in many regions). Use it as another generative UI on top of Crane Ledger.

Prerequisites

  1. A Mistral Le Chat account.
  2. A Crane Ledger account — API key or OAuth if the connector UI supports it.

MCP endpoint

SettingValue
URLhttps://api.craneledger.ai/mcp
TransportStreamable HTTP
Auth (OAuth)Sign in at consent UI — no key in the client
Auth (API key)Authorization: Bearer ha_live_…
Consenthttps://craneledger.ai/oauth/consent

Organization scope comes from your OAuth token or API key — you do not pass organization_id separately.

Scopes: ledger:read, ledger:write, and optionally ledger:admin.

See Authentication and MCP tools.

Add a custom connector

  1. In Le Chat, open Intelligence → Connectors (wording may vary).
  2. Add connector → Custom MCP Connector.
  3. Name: Crane Ledger.
  4. URL: https://api.craneledger.ai/mcp.
  5. Configure authentication (API key / Bearer, or OAuth if offered).
  6. Create the connector and enable it in the conversation.

Example prompts

Once connected, try:

  • "Set up a basic chart of accounts for a small service business"
  • "Create an invoice for $2,500 to Acme Corp for consulting"
  • "What's our cash position right now?"
  • "Show me profit and loss for last quarter"
  • "How many credits do I have left?"
