Overview

AI-generated overview

Remote MCP server that lets an assistant draft, validate and issue Chinese electronic invoices (数电票) from order details, then query invoice records.

What you can do
  • Draft invoices from order text or structured line items, with automatic validation of buyer tax ID format, tax rates and amount limits, plus tax and total calculation
  • Confirm a draft and formally issue the invoice, returning invoice number and delivery information
  • Query drafts and issued invoices under the current App Key, filtered by draft, issued or all
  • Read service description, pricing and contact details without an App Key
When to use it
Useful when you want to turn order or purchase details into a Chinese electronic invoice through conversation, with a free draft step to check tax ID, rates and totals before paying to issue. Also handy for looking up which invoices were drafted or issued under your key.
Requirements
Remote streamable HTTP endpoint; no local install. A purchased App Key sent in the X-App-Key header is required for issuing and querying; the service info tool and draft creation work without it. Network access to the provider's endpoint.
Before you install
Issuing an invoice is a paid, per-invoice action that consumes your purchased quota, so confirm drafts before issuing. The App Key is a secret tied to your billing account and should be kept private. Invoice data, including buyer tax IDs and amounts, is sent to the third-party provider.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.imoldyoung%2Fe-invoice/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
