A time tracking API and MCP server, free for everyone

How it works

1. Create a personal API token in Settings → API tokens. Copy it once; Hourtick only stores a hash.
2. Try the endpoints in the browser at /developers/playground, generated from the OpenAPI spec.
3. Call the REST API with Authorization: Bearer ht_… from a script, a Zap or a spreadsheet.
4. Connect an AI app to https://hourtick.com/api/mcp. Claude.ai and ChatGPT sign in with OAuth; coding agents take a token.
5. Ask it for something real: start a timer, fill your timesheet, summarize last month for a client.

A REST API that matches the app

• Tasks with subtasks, dependencies, comments, checklists and files
• Time entries, timers, projects, clients, task types and cost rates
• Reports, including agent outcomes, cost reconciliation and client AI work reports
• Notes and files on projects and clients, with Markdown for notes
• Chat, search, presence and usage
• An OpenAPI spec, generated from the same schemas the server checks, and a playground to try it

An MCP server your AI can sign in to

The Model Context Protocol is the open standard AI apps use to talk to tools. Hourtick's server runs over streamable HTTP and supports the current OAuth 2.1 authorization flow with PKCE and Client ID Metadata Documents, so Claude.ai, ChatGPT and other apps connect by signing in, with no copying of tokens. Connected apps are listed in Settings, and disconnecting one stops it immediately.

Hourtick is also packaged as a plugin for the ChatGPT and Codex directory and the Grok Build marketplace, and has a publisher presence for Cursor.

What an assistant can do

• Start and stop timers, log time and list your entries
• Read reports and answer "what can we bill Acme this month?"
• Create, update and comment on tasks, and read and post in chat
• Draft your timesheet from your day (see AI timesheet)
• Work with notes and files on projects and clients
• As an agent: take work, ask questions, hand parts to other agents and log billable time

Safe by default

A personal token acts as you, in your workspace, with your role, and nothing more. Agents are limited to what an ordinary member can do and can be scoped further (see Agent governance). Every tool declares whether it only reads, writes or reaches outside Hourtick, so apps can ask before they act. Revoke a token or disconnect an app and it stops working at once.

Setup guides for every AI app

There's a step-by-step guide for each app, sorted by where it runs: Claude Code, Codex, Cursor, Grok Build and Muse Code on your computer; Grok Team Bots, Muse agents, Cursor cloud agents and OpenAI dots in the cloud; and Claude.ai, ChatGPT and Microsoft 365 Copilot in a chat. Or paste the install prompt into your AI and let it set itself up.
