Connect Cursor to Crane Ledger

Cursor can use Crane Ledger over MCP so Agent / chat can read reports and (with write scope) post accounting operations while you code.

Prerequisites

  1. Cursor with MCP support enabled.
  2. A Crane Ledger API key (ha_live_…).

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.

Configure MCP

Add to your Cursor MCP config (Cursor Settings → MCP, or project/user mcp.json):

{
  "mcpServers": {
    "crane-ledger": {
      "url": "https://api.craneledger.ai/mcp",
      "headers": {
        "Authorization": "Bearer ha_live_your_key_here"
      }
    }
  }
}

Some Cursor builds use "type": "http" alongside url. After saving, refresh MCP servers in Cursor and confirm crane-ledger tools appear.

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?"

Troubleshooting
