Manage Hiveage clients, invoices, estimates and payments; send invoices and record payments. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Hiveage connector, then ask in plain words. The AI picks the tools.
For freelancers and small businesses who send invoices and estimates with Hiveage.
The AI lists invoices by state (draft, sent, viewed, partial or paid) with totals and dates, and adds up what is still outstanding.
The AI finds a client in your network and lists their invoices, estimates and recurring invoices.
The AI lists recurring invoice profiles with interval and next billing date, the invoices one profile made, and your saved line items with price and unit.
The AI creates an invoice or estimate with a unique statement number for a client. It starts as a draft and nothing is emailed. It can add the client first.
Changes dataThe AI enters a payment received on an invoice, and marks an offline payment such as a bank transfer as realized so it counts as received.
Changes dataThe AI emails an invoice or estimate to the client, or a payment reminder for an invoice, with the default template or your own text. It cannot be undone.
Changes dataThe login page asks for your Hiveage subdomain and Hiveage API key.
Your subdomain is the part before .hiveage.com in your account address. Find the API key in Hiveage Launchpad > Your Global Profile; it acts with your own permissions. Your key is used only to call the Hiveage API on your behalf; it is never shown to anyone.
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": {
"hiveage": {
"url": "https://hiveage.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"hiveage": {
"type": "http",
"url": "https://hiveage.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 Hiveage subdomain and Hiveage API 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.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper account | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per account | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Hiveage server only. Ask your AI to run hiveage_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with hiveage_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with hiveage_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 Hiveage. The server calls the Hiveage API with your own Hiveage 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 Hiveage subdomain and Hiveage API 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 server signs you in with OAuth: the login page asks for your Hiveage subdomain and Hiveage API 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Hiveage 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 Hiveage.
Yes, if you approve it. 11 of the 28 Hiveage tools can create or change data. The other 17 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Hiveage server only. Cancel any time: your paid plan then runs to the end of the paid period. Run hiveage_usage_status to see how many calls you used.
Ask the AI to run hiveage_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run hiveage_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with hiveage_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.
