Connect your AI to Crane Ledger

Crane Ledger is the ledger of record. Your AI tool of choice is the generative UI — you ask in natural language; the model calls Crane Ledger over MCP or REST.

You → ChatGPT / Claude / Copilot / … → MCP or REST → Crane Ledger → books

Building an agent or MCP integration? Start with Crane Ledger for AI builders — what the ledger is, why real books beat a QBO wrapper, pricing, and the first prompt to run.

The future of accounting is agent-run: Agent-run accounting — why you should not sign into QuickBooks every day.

REST vs MCP is a client choice. Same organizations, credits, and double-entry rules either way.

1. Create a Crane Ledger account

Browser: Sign up at craneledger.ai with GitHub, Google, Apple, or an email magic link. New orgs get 500 free credits. GitHub is optional.

Agent / API (no browser):

curl -s https://api.craneledger.ai/accounts/master \
  -H "Content-Type: application/json" \
  -d '{"name":"My Business","base_currency_code":"USD"}'

Save the one-time api_key (ha_live_…) and organization_id.

2. Pick how to connect

MCP endpoint

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.

3. Choose your client

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?"
