Connect ChatGPT and Claude.ai by signing in
Hourtick's MCP server now supports OAuth 2.1, so Claude.ai, Claude Desktop, ChatGPT and other apps connect by signing in to Hourtick instead of pasting a token.
What's new
- Add Hourtick as a custom connector in Claude, or as an app in ChatGPT developer mode
- Sign in on hourtick.com and approve; no token to copy
- See and disconnect connected apps in Settings; they stop at once
- Tokens only work on Hourtick's MCP server and refresh on their own
- Built on the MCP 2026-07-28 authorization spec: PKCE, Client ID Metadata Documents, Dynamic Client Registration
Coding agents like Claude Code, Codex, Grok Build and Muse Code take a token in a config file. The apps most people use can't: Claude.ai and ChatGPT expect to sign in to the services they connect to. Now they can. Paste https://hourtick.com/api/mcp, sign in to Hourtick, approve, and the app can track time, work with tasks and chat as you.
Connected apps are listed in Settings, where you can disconnect one with a click; its access stops immediately. In ChatGPT, OpenAI allows write actions from custom apps on Business, Enterprise and Edu plans.
