What you can do with Zenbooker in Claude and ChatGPT
For home service businesses who schedule jobs and customers in Zenbooker.
See scheduled jobs and who is assigned
The AI lists jobs in a start-time window, filtered by status, territory or team member. It opens one for the address, services, providers and notes.
Find a customer and their jobs
The AI searches customers by name, email or phone, or by distance from a place, and opens one for addresses, notes, job ids and recurring bookings.
Find unpaid invoices and failed payments
The AI lists invoices by status such as unpaid or partial_paid, with amount due, and payment transactions by status such as failed.
Find open time slots for a service area
The AI checks if a location is in a service area, then gets available time slots of a territory by day for a service duration in minutes.
Review incoming booking and quote requests
The AI lists service requests with status, customer, requested dates, services and pricing. You see what needs an answer.
Add a customer or a note on a job
The AI creates a customer record, after a search to avoid duplicates, or adds an internal note to a job. Notes cannot be deleted through this server.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"zenbooker": {
"url": "https://zenbooker.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"zenbooker": {
"type": "http",
"url": "https://zenbooker.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
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 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.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper API key | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per API key | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Zenbooker server only. Ask your AI to run zenbooker_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 zenbooker_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 zenbooker_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4
- Usage status (free-tier meter)
zenbooker_usage_statusReport the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. - Request a missing feature
zenbooker_request_featureTell 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. - Upgrade to Pro or Pro+
zenbooker_upgradeGet a paid plan for Zenbooker (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
zenbooker_cancel_subscriptionCancel the caller's Zenbooker Pro subscription at the end of the paid period (no refund for the current period; Pro continues 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.
FAQ
What can I do with Zenbooker in Claude or ChatGPT?
See scheduled jobs and who is assigned. Find a customer and their jobs. Find unpaid invoices and failed payments. Find open time slots for a service area. Review incoming booking and quote requests. Add a customer or a note on a job. See what you can do for the details.
Is this an official Zenbooker product?
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.
Can I connect Zenbooker to Claude or ChatGPT?
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.
What do I need to connect?
The login page asks for your Zenbooker API key. See Before you connect for where to find it.
Do I put my Zenbooker key or an Authorization header in the client config?
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.
How do you keep my Zenbooker credentials?
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.
Can the AI change my Zenbooker data?
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.
What does it cost?
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 Zenbooker server only. Cancel any time: your paid plan then runs to the end of the paid period. Run zenbooker_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run zenbooker_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 zenbooker_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Zenbooker tool that I need is missing?
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.
Which AI clients can I use?
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.
