What you can do with Clockify in Claude and ChatGPT

For freelancers, agencies and teams who track time on projects and clients in Clockify.

Summarize tracked hours by project, user or client

The AI runs a summary report for a date range, grouped for example by user then project, with tracked time and amounts, so you see where hours went.

List every time entry in a period

The AI reads a detailed report of all time entries, with user, project, client, task, tags, description and duration, or one user's entries with filters.

Check if a timer is running and on what

The AI reads the running timer of a user and tells you the project and description, or that no timer is running.

Review projects, clients, tasks and tags

The AI lists projects with client, billable flag and tracked duration, and the clients, tasks and tags of your workspace.

Log time, start a timer or stop it

The AI adds a finished time entry for you, or starts a running timer on a project, and stops the running timer at a time you choose.

Changes data

Correct or delete a time entry

The AI changes a time entry's start, end, description, project, task, tags or billable flag, or permanently deletes it.

How do I connect Clockify?

Before you connect

The login page asks for your Clockify API key and Data region.

Optional: Workspace subdomain (only for a regional workspace on its own subdomain).

Create the key in Clockify → Profile settings → Advanced → Manage API keys → Generate new. The key acts with your permissions in each workspace. The data region is shown in Workspace settings; most workspaces are Global. A workspace on its own subdomain (acme.clockify.me) needs a key generated while you are in that workspace. Your key is used only to call the Clockify 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 Clockify and this URL, then click Add:
https://clockify.usefulapi.io/mcp
Claude opens the login page: enter your Clockify API key and Data region.
In a chat, click + → Connectors and turn on Clockify.

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 Clockify and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://clockify.usefulapi.io/mcp
ChatGPT opens the login page: enter your Clockify API key and Data region.
In Plugins, install Clockify, 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 clockify https://clockify.usefulapi.io/mcp

Cursor

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

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

VS Code

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

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

Codex

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

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

codex mcp login clockify

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://clockify.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 Clockify API key and Data region. 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 Clockify server only. Ask your AI to run clockify_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 clockify_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 clockify_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Log time or start a timerclockify_create_time_entry
WRITE: add a time entry for yourself. With end = a finished entry (log time); without end = a running timer that starts at start (default now). A workspace with required custom fields may refuse it.
Stop running timerclockify_stop_timer
WRITE: stop the running timer of a user (default: you) at end (default now). Clockify answers 404 if no timer is running.
Update a time entryclockify_update_time_entry
WRITE: change a time entry's start, end, description, project, task, tags or billable. Only the fields you pass change: the entry is read first and every other field (custom fields included) is sent back as it was. The entry is rewritten (PUT) from a fresh read, so an edit made to the same entry in between (e.g. in the Clockify app) can be lost. A new project without task_id clears the task. GET then PUT /v1/workspaces/{workspaceId}/time-entries/{id}.
Delete a time entryclockify_delete_time_entry
WRITE (destructive): permanently delete one time entry. It cannot be undone.
Create a projectclockify_create_project
WRITE: create a project in a workspace (needs an admin or project-manager role, depending on workspace settings).
Create a taskclockify_create_task
WRITE: add a task to a project.

Your usefulapi plan · 4

Usage status (free-tier meter)clockify_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 featureclockify_request_feature
Tell usefulapi that the user needs something the Clockify 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+clockify_upgrade
Get a paid plan for Clockify (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 subscriptionclockify_cancel_subscription
Cancel the caller's Clockify 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 clockify_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Clockify in Claude or ChatGPT?

Summarize tracked hours by project, user or client. List every time entry in a period. Check if a timer is running and on what. Review projects, clients, tasks and tags. Log time, start a timer or stop it. Correct or delete a time entry. See what you can do for the details.

Is this an official Clockify product?

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

Can I connect Clockify 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 Clockify API key and Data region. See Before you connect for where to find them.

Do I put my Clockify 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 Clockify API key and Data region. 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 Clockify credentials?

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

Can the AI change my Clockify data?

Yes, if you approve it. 8 of the 21 Clockify tools can create or change data. The other 13 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 Clockify server only. Cancel any time: your paid plan then runs to the end of the paid period. Run clockify_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run clockify_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 clockify_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Clockify tool that I need is missing?

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