Tool

What post_journal_entry does

Performs the post journal entry operation against the organization's data.

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 post_journal_entry

Called by an MCP-compatible AI client (Claude Desktop, Claude Code, Cursor, Windsurf, Codex) when the user's prompt maps to this action.

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

post_journal_entry accepts 1 parameter — 1 required, 0 optional. The AI fills these in from your natural-language prompt; you never write them by hand.

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 post_journal_entry call looks like:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "post_journal_entry",
    "arguments": {
      "id": "id_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 post_journal_entry automatically.

What is post_journal_entry?▾

post_journal_entry is one of 102 tools in InvoiceCave's MCP server. Performs the post journal entry operation against the organization's data. 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 post_journal_entry?▾

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 post_journal_entry 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 post_journal_entry take?▾

Does post_journal_entry 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.
