What you can do with HappyFox in Claude and ChatGPT

For support agents and help desk managers who work tickets in HappyFox.

Find open tickets by status, priority or assignee

The AI lists or searches tickets with filters such as status, priority and assignee, newest activity first. You see what needs work.

Read a ticket with its full conversation

The AI opens a ticket with its status, priority, assignee, SLA breaches and every update, including messages and private notes. It can sum up the thread.

Check saved reports

The AI lists saved reports, reads their summary counts and shows the ticket rows of a report. You get numbers without opening the Reports module.

Look up a customer and their company

The AI finds contacts by name or email, reads one with phones, groups and ticket counts, and opens a contact group with its member contacts.

Reply, add a private note or update a ticket

The AI adds an agent reply or an internal note to a ticket, and can change its status, priority, assignee, due date or tags. The customer is emailed only on a reply when you ask for it.

How do I connect HappyFox?

Before you connect

The login page asks for your Help-desk subdomain, Region, API key and Auth code.

Your subdomain is the first part of your help-desk address, e.g. acme for acme.happyfox.com (EU accounts use .happyfox.net). Create the key in HappyFox under Manage → Integrations → API → Create API key (older accounts: Apps → Goodies → API), then use its see auth code action to copy the auth code.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name HappyFox and this URL, then click Add:
https://happyfox.usefulapi.io/mcp
Claude opens the login page: enter your Help-desk subdomain, Region, API key and Auth code.
In a chat, click + → Connectors and turn on HappyFox.

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 HappyFox and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://happyfox.usefulapi.io/mcp
ChatGPT opens the login page: enter your Help-desk subdomain, Region, API key and Auth code.
In Plugins, install HappyFox, 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 happyfox https://happyfox.usefulapi.io/mcp

Cursor

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

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

VS Code

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

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

Codex

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

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

codex mcp login happyfox

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://happyfox.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 Help-desk subdomain, Region, API key and Auth code. 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 HappyFox server only. Ask your AI to run happyfox_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 happyfox_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 happyfox_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

Usage status (free-tier meter)happyfox_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 featurehappyfox_request_feature
Tell usefulapi that the user needs something the HappyFox 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+happyfox_upgrade
Get a paid plan for HappyFox (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 subscriptionhappyfox_cancel_subscription
Cancel the caller's HappyFox 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 happyfox_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with HappyFox in Claude or ChatGPT?

Find open tickets by status, priority or assignee. Read a ticket with its full conversation. Check saved reports. Look up a customer and their company. Reply, add a private note or update a ticket. See what you can do for the details.

Is this an official HappyFox product?

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

Can I connect HappyFox 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 Help-desk subdomain, Region, API key and Auth code. See Before you connect for where to find them.

Do I put my HappyFox 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 Help-desk subdomain, Region, API key and Auth code. 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 HappyFox credentials?

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

Can the AI change my HappyFox data?

Yes, if you approve it. 7 of the 23 HappyFox 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 HappyFox server only. Cancel any time: your paid plan then runs to the end of the paid period. Run happyfox_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run happyfox_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 happyfox_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a HappyFox tool that I need is missing?

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