How do I connect Schedule it?

Before you connect

The login page asks for your Account number, Login name and Password.

Schedule It's API signs in with a normal account login: the user name is <account number>_<login name> (shown in your Schedule It account settings) and its password. A dedicated login for the AI assistant keeps its activity easy to track and limits what it can see. Your login is used only to call the Schedule It API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Schedule it and this URL, then click Add:
https://schedule-it.usefulapi.io/mcp
Claude opens the login page: enter your Account number, Login name and Password.
In a chat, click + → Connectors and turn on Schedule it.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name Schedule it and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://schedule-it.usefulapi.io/mcp
ChatGPT opens the login page: enter your Account number, Login name and Password.
In Plugins, install Schedule it, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http schedule-it https://schedule-it.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "schedule-it": {
      "url": "https://schedule-it.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "schedule-it": {
      "type": "http",
      "url": "https://schedule-it.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add schedule-it --url https://schedule-it.usefulapi.io/mcp

codex mcp login schedule-it

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.

https://schedule-it.usefulapi.io/mcp

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 Account number, Login name and Password. 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 user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Schedule it server only. Ask your AI to run scheduleit_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 scheduleit_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 scheduleit_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

List eventsscheduleit_list_events
List scheduled events and tasks (bookings, shifts, jobs). Without date_from/date_to Schedule It uses its default date range. Schedule It returns only a short summary of each event unless you name the fields you want: pass `fields` such as id,title,date_start,date_end,owner,notes,completed,priority,custom1 (get_event returns ALL fields of one event). `owner` holds the ids of the resources (people, rooms, equipment) the event is linked to. There is no paging: the reply holds up to `limit` events (default 100), so narrow with the filters instead. Do not call this repeatedly to watch for changes (use modified_after to fetch only what changed).
Get eventscheduleit_get_event
One event or task by id with ALL its fields (title, dates, linked resources, notes, completion, priority, custom fields).
List resourcesscheduleit_list_resources
List resources: the people, rooms, equipment or vehicles that events are scheduled against. Schedule It returns only a short summary unless you pass `fields` (for example id,name,email,data1; get_resource returns ALL fields of one). Resources belong to groups (`owner` = group ids). There is no paging; the reply holds up to `limit` resources (default 100).
Get resourcescheduleit_get_resource
One resource by id with ALL its fields (name, email, groups, details 1-10, colours, skills).
List groupsscheduleit_list_groups
List resource groups (the categories resources are organised in, e.g. Staff, Rooms, Vehicles). Pass `fields` (e.g. id,name) for more than the short summary.
Get groupscheduleit_get_group
One resource group by id with ALL its fields.
List labelsscheduleit_list_labels
List the labels that can be put on events (for example Confirmed, Urgent). Pass `fields` (e.g. id,name) for more than the short summary.
List label groupsscheduleit_list_label_groups
List label groups (the categories that labels are organised in). Pass `fields` (e.g. id,name) for more than the short summary.

Changes data · 7

Create eventscheduleit_create_event
WRITE: create a new event (booking, shift, job or task) in the Schedule It account, optionally linked to resources. It becomes visible to everyone with access to the schedule, and Schedule It may notify the linked resources according to the account's own notification settings. Confirm the title, dates and resources with the user first.
Update eventscheduleit_update_event
WRITE: change fields of an existing event; only the fields you pass are changed, the rest stay as they are. Passing resource_ids replaces the whole list of linked resources; an empty string clears notes or a custom field. Changing dates or resources may notify people per the account's notification settings.
Delete eventscheduleit_delete_event
WRITE, DESTRUCTIVE: permanently delete one event or task. It cannot be undone through the API. Only call this when the user clearly asked for this event to be deleted.
Create resourcescheduleit_create_resource
WRITE: add a new resource (a person, room, piece of equipment) to the Schedule It account. It may count toward the account's licensed resources or users. Confirm the details with the user first.
Update resourcescheduleit_update_resource
WRITE: change fields of an existing resource; only the fields you pass are changed. Passing group_ids replaces the whole list of groups; an empty string clears email or a detail field.
Create groupscheduleit_create_group
WRITE: add a new resource group to the Schedule It account.
Update groupscheduleit_update_group
WRITE: change fields of an existing resource group; only the fields you pass are changed.

Your usefulapi plan · 4

Usage status (free-tier meter)scheduleit_usage_status
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.
Request a missing featurescheduleit_request_feature
Tell usefulapi that the user needs something the Schedule It 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+scheduleit_upgrade
Get a paid plan for Schedule It (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 subscriptionscheduleit_cancel_subscription
Cancel the caller's Schedule It 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 scheduleit_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Schedule it in Claude or ChatGPT?

See what is on the schedule and who it is assigned to. Find events that changed since a given time. List the resources of a group with their details. Create an event for a resource. Change or delete an event. Add or change a resource or a resource group. See what you can do for the details.

Is this an official Schedule it product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Schedule it. The server calls the Schedule it API with your own Schedule it access, so it sees only the data that your account can see.

Can I connect Schedule it 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 Account number, Login name and Password. See Before you connect for where to find them.

Do I put my Schedule it 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 Account number, Login name and Password. 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 Schedule it credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Schedule it 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 Schedule it.

Can the AI change my Schedule it data?

Yes, if you approve it. 7 of the 15 Schedule it tools can create or change data. The other 8 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 Schedule it server only. Cancel any time: your paid plan then runs to the end of the paid period. Run scheduleit_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run scheduleit_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 scheduleit_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Schedule it tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with scheduleit_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.
