Look up invoices, allowances and number ranges, and check government upload status in amego. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the amego connector, then ask in plain words. The AI picks the tools.
For companies in Taiwan that issue e-invoices and allowances with amego.
Look up one invoice by its number or its order number. Get a PDF link for it, valid for 10 minutes.
List the invoices of a date range, then check up to 50 invoice numbers for government upload status.
List the number ranges for one period and see how many numbers remain in each.
List the allowances of a date range, then open one by its allowance number to read it.
List the company's invoices that won a prize in one two-month period.
The login page asks for your Company tax ID (統一編號, 8 digits) and amego App Key.
Ask amego customer service for the App Key of your company (amego). The App Key only signs requests and is never shown to anyone. Use the tax ID of the company that holds the App Key.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"amego": {
"url": "https://amego.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"amego": {
"type": "http",
"url": "https://amego.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Company tax ID (統一編號, 8 digits) and amego App Key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

No. usefulapi is an independent service. It is not affiliated with or endorsed by amego. The server calls the amego API with your own amego access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Company tax ID (統一編號, 8 digits) and amego App Key. See Before you connect for where to find them.
No. Add only the URL. Do not add an Authorization header or an API key to the client config.

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the amego API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in amego.
All 13 amego tools are marked read-only.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this amego server only. Cancel any time: Pro then runs to the end of the paid period. Run amego_usage_status to see how many calls you used.
Ask the AI to run amego_upgrade: it returns a Stripe Checkout link. To cancel, run amego_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with amego_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
