What you can do with Kayako in Claude and ChatGPT

For customer support agents and team leads who work cases in Kayako.

List open cases and who is assigned to them

The AI lists cases filtered by status type, tags, priority level or requester, so you see what is open. It can expand the assignee and team of each case.

Read a case timeline and summarize it

The AI opens a case and reads its posts, with customer messages, agent replies and internal notes, and tells you what happened so far.

Find all cases of a customer organization

The AI searches for an organization and lists the cases raised by its members, so you see how many there are and what they are about.

Find help-center articles for an answer

The AI searches the help center and opens articles with their localized title, content, section and tags, so you can answer a customer from them.

Create a customer user, or create or update a case

The AI creates a customer user, opens a case for a requester, or changes a case's status, priority, assignee, tags or custom fields.

Changes data

Add an internal note or reply, and set status

The AI adds an internal note that only agents see, or sends a public reply on a channel such as MAIL, and can set status, priority or assignee in the same step.

How do I connect Kayako?

Before you connect

The login page asks for your Kayako instance, Agent email and Password.

Your email and password are stored encrypted in this connection's authorization grant and used only to sign in to your Kayako instance and call the Kayako API on your behalf. They are never shown to anyone; the instance and email are also hashed into a private account id for usage metering.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Kayako and this URL, then click Add:
https://kayako.usefulapi.io/mcp
Claude opens the login page: enter your Kayako instance, Agent email and Password.
In a chat, click + → Connectors and turn on Kayako.

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 Kayako and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://kayako.usefulapi.io/mcp
ChatGPT opens the login page: enter your Kayako instance, Agent email and Password.
In Plugins, install Kayako, 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 kayako https://kayako.usefulapi.io/mcp

Cursor

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

{
  "mcpServers": {
    "kayako": {
      "url": "https://kayako.usefulapi.io/mcp"
    }
  }
}

VS Code

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

{
  "servers": {
    "kayako": {
      "type": "http",
      "url": "https://kayako.usefulapi.io/mcp"
    }
  }
}

Codex

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

codex mcp add kayako --url https://kayako.usefulapi.io/mcp

codex mcp login kayako

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://kayako.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 Kayako instance, Agent email 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 Kayako server only. Ask your AI to run kayako_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 kayako_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 kayako_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Create a casekayako_create_case
WRITE: open a new case (conversation) for a requester. channel MAIL sends the first message to the customer by email from the mailbox given as channel_id; channel NOTE creates it with an internal note and emails nobody. Get channel ids from kayako_list_channels and status/priority/type ids from kayako_list_case_options.
Update a casekayako_update_case
WRITE: change a case's subject, requester, assignee (team/agent), status, priority, type, brand, form, tags or custom fields. Sends nothing to the customer. `tags` sets the case's tag list (use kayako_add_case_tags to append). Trashing is deliberately not exposed.
Reply to a case or add an internal notekayako_reply_to_case
WRITE: add a post to a case. channel NOTE adds an INTERNAL note visible only to agents (no channel_id needed). channel MAIL/TWITTER/FACEBOOK sends a PUBLIC reply to the customer — get channel_id from kayako_list_channels with case_id. Can also set status/priority/assignee in the same call.
Add tags to a casekayako_add_case_tags
WRITE: add tags to a case, keeping its existing tags.
Create a userkayako_create_user
WRITE: create a user — typically a CUSTOMER to use as requester_id on a new case. role_id comes from kayako_list_roles. Collaborator/agent/admin roles also require email and team_ids. No password is set by this tool.

Your usefulapi plan · 4

Usage status (free-tier meter)kayako_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 featurekayako_request_feature
Tell usefulapi that the user needs something the Kayako 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+kayako_upgrade
Get a paid plan for Kayako (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 subscriptionkayako_cancel_subscription
Cancel the caller's Kayako 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 kayako_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Kayako in Claude or ChatGPT?

List open cases and who is assigned to them. Read a case timeline and summarize it. Find all cases of a customer organization. Find help-center articles for an answer. Create a customer user, or create or update a case. Add an internal note or reply, and set status. See what you can do for the details.

Is this an official Kayako product?

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

Can I connect Kayako 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 Kayako instance, Agent email and Password. See Before you connect for where to find them.

Do I put my Kayako 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 Kayako instance, Agent email 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 Kayako credentials?

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

Can the AI change my Kayako data?

Yes, if you approve it. 5 of the 21 Kayako tools can create or change data. The other 16 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 Kayako server only. Cancel any time: your paid plan then runs to the end of the paid period. Run kayako_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run kayako_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 kayako_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Kayako tool that I need is missing?

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