What create_item does
Creates a new item in the organization. Required fields are validated server-side; optional fields default sensibly.
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 create_item
Use when the AI needs to record something new — typically as the final step of a "set this up for me" workflow. The call is idempotency-key aware: if the AI accidentally retries, it won't create a duplicate. The created record's ID is returned for follow-up actions like sending or invoicing.
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
create_item accepts 7 parameters — 2 required, 5 optional. The AI fills these in from your natural-language prompt; you never write them by hand.
| Parameter | Type | Required | Description |
|---|---|---|---|
| name | string | required | Item name (required) |
| rate | number | required | Price/rate per unit (required) |
| type | enum | optional | Item typeServiceGoods |
| description | string | optional | Item description |
| tax | number | optional | Tax percentage |
| sku | string | optional | Stock keeping unit / catalog code |
| unit | string | optional | Unit of measure (e.g. "hour", "kg", "license") |
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 create_item call looks like:
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "create_item",
"arguments": {
"name": "Acme Corp",
"rate": 10,
"type": "Service",
"description": "Thanks for your business",
"tax": 10
}
}
}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 create_item automatically.

FAQ — create_item
What is create_item?▾
create_item is one of 102 tools in InvoiceCave's MCP server. Creates a new item in the organization. Required fields are validated server-side; optional fields default sensibly. 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 create_item?▾
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 create_item 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 create_item take?▾
create_item accepts 7 parameters — 2 required (name, rate) and 5 optional. The AI populates these from your plain-English prompt — see the parameter table and request example above.
Does create_item 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.
