阅读 https://sourceweft.com/mcp/io.usefulapi%2Ftimetac/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}Use your TimeTac account from Claude, Cursor, or any MCP client. Read employees, time entries, absences, projects and tasks, and start timers, add time entries or handle leave requests. Hosted, no local install: connect with your own credentials.
Live endpoint: https://timetac.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://timetac.usefulapi.io/mcp.claude mcp add --transport http timetac https://timetac.usefulapi.io/mcp, then run /mcp to log in.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, and the login page asks for your TimeTac credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/timetac/
On first connect you provide your TimeTac account name, and the client id and client secret of an API client (TimeTac → Account settings → API Credentials; ask [email protected] to enable the API if it is missing). The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with timetac_upgrade (it returns a Stripe Checkout link). Cancel any time with timetac_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running timetac_upgrade before then undoes the cancel. Or write to [email protected].
