delete_expense
Delete an expense. If it had a bankAccountId, the deducted amount is added back to the balance.
What delete_expense does
Permanently deletes the specified expense. Most domains soft-delete (the record stays in the audit log) so this is reversible by an admin.
This tool is part of InvoiceCave's open MCP server — the most MCP-complete invoicing platform on the market with 102 tools covering invoices, customers, quotes, expenses, payments, recurring schedules, accounting, and reports. Every tool is callable from any MCP-compatible AI client without writing a single line of integration code.
How an AI uses delete_expense
The AI should always confirm with the user before calling a delete_* tool. InvoiceCave's audit log records the source as 'mcp' so you can always trace which AI client and which tool call removed the record.
You don't call this tool directly — you ask the AI in plain English and the MCP client decides which tool to invoke based on your request. The example prompts below were lifted from real Claude Desktop sessions, so you can use them verbatim or adapt them to your data.
Parameters
delete_expense accepts 1 parameter — 1 required, 0 optional. The AI fills these in from your natural-language prompt; you never write them by hand.
| Parameter | Type | Required | Description |
|---|---|---|---|
| expenseId | string | required | Expense ID |
Request example
Under the hood, your AI client sends a JSON-RPC 2.0 tools/call request to InvoiceCave's MCP endpoint at https://www.invoicecave.com/api/mcp/mcp. Here's what a delete_expense call looks like:
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "delete_expense",
"arguments": {
"expenseId": "exp_a1b2c3d4"
}
}
}You won't write this yourself — it's shown so developers can see exactly what the MCP client generates. The arguments object maps 1:1 to the parameters above. Authentication is handled by the Authorization: Bearer header with your API key.
Example AI prompts
Type any of these into Claude Desktop, Claude Code, or Cursor — InvoiceCave's MCP server will route them to delete_expense automatically.
“Delete this expense (I'll confirm first).”

FAQ — delete_expense
What is delete_expense?▾
delete_expense is one of 102 tools in InvoiceCave's MCP server. Permanently deletes the specified expense. Most domains soft-delete (the record stays in the audit log) so this is reversible by an admin. It's invoked automatically when an AI client like Claude or Cursor decides the user's request maps to this action.
Which AI clients can call delete_expense?▾
Any MCP-compatible client. We've tested it with Claude Desktop, Claude Code, Cursor, Windsurf, and Codex. The MCP protocol is open, so any AI tool that speaks MCP can call this endpoint with a valid InvoiceCave API key.
Is calling delete_expense secure?▾
Yes. Every call is authenticated by the API key you mint in the dashboard, scoped to a single organization, rate-limited per key, and recorded in the audit log with source='mcp'. Sensitive fields (SMTP passwords, encryption keys) are never returned to the AI client.
What parameters does delete_expense take?▾
delete_expense accepts 1 parameter — 1 required (expenseId). The AI populates these from your plain-English prompt — see the parameter table and request example above.
Does delete_expense count against any quota?▾
MCP tool calls are unmetered on the free plan up to a generous monthly limit. Once you connect Stripe and start charging your customers, every call still counts against the same per-key rate limit but doesn't add to your bill.
