Read Invoiced customers, invoices, payments, subscriptions; create customers, draft invoices, notes. Hosted by usefulapi — connect from Claude, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"invoiced": {
"url": "https://invoiced.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"invoiced": {
"type": "http",
"url": "https://invoiced.usefulapi.io/mcp"
}
}
}Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your Invoiced API key and Environment.
In Invoiced go to Settings → Developers → API Keys and create a key (one key per application is recommended). Choose Production for your live account or Sandbox for sandbox.invoiced.com. Your key is used only to call the Invoiced API on your behalf and to derive a private account id; it is never shown to anyone.
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 Invoiced API key and Environment. 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.

Does not count against the meter. | |
invoiced_cancel_subscription | Cancel the Pro subscription Cancel the caller's Invoiced Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue until then, then the free tier applies). Requires confirm: true. Run invoiced_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 100 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited |
Pro covers this Invoiced server only. Subscribe with invoiced_upgrade (it returns a Stripe Checkout link). Cancel any time with invoiced_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running invoiced_upgrade before then undoes the cancel. Or write to [email protected].
No. usefulapi is an independent service. It is not affiliated with or endorsed by Invoiced. The server calls the Invoiced API with your own Invoiced access, so it sees only the data that your account can see.
The login page asks for your Invoiced API key and Environment. 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 server signs you in with OAuth: the login page asks for your Invoiced API key and Environment. 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Invoiced 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 Invoiced.
Yes, if you approve it. 4 of the 27 Invoiced tools can create or change data. The other 23 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Invoiced server only. Run invoiced_usage_status to see how many calls you used.
Ask the AI to run invoiced_upgrade: it returns a Stripe Checkout link. To cancel, run invoiced_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 invoiced_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, 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.
