TimeTac and AI: Is there an MCP server for TimeTac?

TimeTac by TimeTac GmbH from Graz, Austria, is software for time tracking, absences and project times. If you want an AI assistant such as Claude, ChatGPT or Microsoft Copilot to work with TimeTac data, the first question is: is there an MCP server for it?

In short

We found no official MCP server from TimeTac. There is a REST API, and an open-source connector and a commercial service from third parties build on it.

What TimeTac offers itself

A REST API. The API v6 reads and writes time tracking, absences, projects and people. It uses OAuth 2.0 with client credentials. According to TimeTac, every account is isolated, and the credentials reach only your own company’s data. According to the help centre, admins create API keys, each with a client ID and a client secret, and the secret appears only once. According to the documentation, the paths of versions 1 to 5 belong to an older API. On the plan: according to the API documentation, the feature for API credentials (api_users) is by default in Standard and Advanced and is not marked as included in Essential. The documentation calls the table a guide, and it can differ per customer. TimeTac’s pricing page says nothing on this that we found.

Suggested time entries. On its AI time tracking page, TimeTac describes how the desktop app for Windows and Mac combines calendar events and detected apps, documents and browser pages into suggested time entries. Your team reviews and confirms the suggestions. According to TimeTac, each employee switches the feature on individually. According to TimeTac, the feature takes no screenshots, logs no keystrokes and does not train AI models on detected activity. TimeTac explicitly does not call this AI but automated tracking. We found no AI assistant in the product.

Data location. According to TimeTac’s home page, the server location is in the EU. We found no country, host or sub-processors there.

What third parties offer

Neither offer comes from TimeTac. We tested neither. The pages do not prove that TimeTac supports them.

usefulapi (commercial). According to the README, the vendor runs a hosted MCP server at https://timetac.usefulapi.io/mcp. According to its README, it reads users, time entries, absences, projects, tasks, departments and teams. It starts and stops timers, creates time entries and absence requests, and approves or rejects absences. The README names no delete tools for time entries. You sign in with OAuth and enter the account name, client ID and client secret. According to the README, the free plan covers 50 calls per month, and Pro costs 9 US dollars per user and month. The repository holds documentation only, and the server itself is not public.

AnythingMCP (open source). AnythingMCP is an open-source toolkit (AGPL-3.0) with a hosted cloud. According to its pricing page, the cloud starts with a 7-day trial and then costs from 19 euros per month. According to its guide, you can also self-host the toolkit with Docker. The definition of the TimeTac connector sits in the public repository at packages/backend/src/adapters/de/timetac.json. According to its catalogue page, the TimeTac connector has seven tools, all read-only: users, time entries, projects, tasks, absences, departments and the live attendance status. According to the page, the cloud runs in Frankfurt. The connector definition names the REST API v4 at api.timetac.com, while some AnythingMCP guides name v3. We did not check which version runs now.

What this means for your company

A third-party server sees the data that the API key reaches. Therefore:

• The API key covers the whole TimeTac account, not one user. Create a separate key for each connection, so you can delete it on its own.
• Times, absences and people are personnel data. Clarify with data protection and the works council which AI tools may see them, and sign a data processing agreement with the third party if needed.
• Write tools change times and approve absences. If you only want to read, choose a read-only connector or run your own server on the API.
• What reaches the AI assistant falls under its terms, no longer under those of TimeTac.
