List shifts and groups, and filter for open shifts in Inzetrooster. For volunteer and staff coordinators who fill shifts in Inzetrooster. 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": {
"inzetrooster": {
"url": "https://inzetrooster.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"inzetrooster": {
"type": "http",
"url": "https://inzetrooster.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.
List the shifts of the coming weeks and keep only the open ones. The open filter applies to the returned page only.
inzetrooster_list_shifts
List the groups that have shifts in a date window, with the shift count of each. Counts come from the first 500 shifts only, so use a narrow window. Then list the shifts of one group.
inzetrooster_list_groups inzetrooster_list_shifts
List the shifts of one month, filtered by group, location or weekday, to see which shifts are covered.
inzetrooster_list_shifts
List the shifts of one group in a week. The result includes the names of the assigned volunteers, for a reminder list.

The login page asks for your Inzetrooster account name and Inzetrooster API token.
Your account name is the part after inzetrooster.nl/ in your address. Ask Inzetrooster support for an API token (premium accounts only). Your token is used only to read your shifts 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 Inzetrooster account name and Inzetrooster API token. 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 Inzetrooster connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
inzetrooster_list_shifts | read | List shifts List shifts (diensten) of the Inzetrooster account, with group, location, time and the assigned person. Without filters the API returns the next 12 months of published shifts. Includes private groups and volunteer names. Set open_only to keep only shifts with no person assigned (applies to the returned page only). Inzetrooster API: GET /<account>/api/v1/shifts. |
inzetrooster_list_groups | read | List groups List the groups (ploegen) that have shifts in a date window, with the number of shifts per group. Derived from the shifts on the first page (up to 500 shifts): a group with no shifts in the window does not appear. Includes private groups. Use the ids with inzetrooster_list_shifts. |
inzetrooster_usage_status | Usage status (free-tier meter) Report 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. | |
inzetrooster_request_feature | Request a missing feature Tell usefulapi that the user needs something the Inzetrooster 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. | |
inzetrooster_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Inzetrooster (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
inzetrooster_cancel_subscription | Cancel the Pro subscription Cancel the caller's Inzetrooster 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 inzetrooster_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 user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Inzetrooster server only. Subscribe with inzetrooster_upgrade (it returns a Stripe Checkout link). Cancel any time with inzetrooster_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running inzetrooster_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 Inzetrooster. The server calls the Inzetrooster API with your own Inzetrooster 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 Inzetrooster account name and Inzetrooster API token. 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 Inzetrooster account name and Inzetrooster API token. 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 Inzetrooster 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 Inzetrooster.
All 2 Inzetrooster 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 Inzetrooster server only. Cancel any time: Pro then runs to the end of the paid period. Run inzetrooster_usage_status to see how many calls you used.
Ask the AI to run inzetrooster_upgrade: it returns a Stripe Checkout link. To cancel, run inzetrooster_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 inzetrooster_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.
