Read Zenbooker jobs, customers, invoices and timeslots; add customers and job notes. Hosted by usefulapi — connect from Claude, ChatGPT, 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": {
"zenbooker": {
"url": "https://zenbooker.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"zenbooker": {
"type": "http",
"url": "https://zenbooker.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
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 Zenbooker API key.
Create it in Zenbooker → Settings → Developers → API → Create API Key. A Zenbooker key has full access to the account. Your key is used only to call the Zenbooker API on your behalf; 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 Zenbooker 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.
Turn on the Zenbooker connector, then ask in plain words. The AI picks the tools.

zenbooker_request_feature | Request a missing feature Tell usefulapi that the user needs something the Zenbooker tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
zenbooker_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Zenbooker tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
zenbooker_cancel_subscription | Cancel the Pro subscription Cancel the caller's Zenbooker 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 zenbooker_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper API key | $9/mo · $90/yr | Unlimited |
Pro covers this Zenbooker server only. Subscribe with zenbooker_upgrade (it returns a Stripe Checkout link). Cancel any time with zenbooker_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running zenbooker_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 Zenbooker. The server calls the Zenbooker API with your own Zenbooker 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 Zenbooker API key. See Before you connect for where to find it.
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 Zenbooker 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 Zenbooker 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 Zenbooker.
Yes, if you approve it. 2 of the 21 Zenbooker tools can create or change data. The other 19 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 unlimited tool calls, for this Zenbooker server only. Run zenbooker_usage_status to see how many calls you used.
Ask the AI to run zenbooker_upgrade: it returns a Stripe Checkout link. To cancel, run zenbooker_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 zenbooker_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.
