Timetastic API and MCP server

The Timetastic API gives a token only to admin users and has no report endpoints. Sign in to Timetastic once in your own Cloud Browser, and your AI agent does the work there for you. The same tools work over MCP for agents and as a REST API for scripts.

Timetastic has no API for this. So we run one for you.

How do I connect Timetastic to Claude, ChatGPT or my code?

AI agents connect over MCP, scripts call the REST API. Both reach the same 9 tools with one API key.

For AI agents: MCP

Add Cotlet to your agent once. Timetastic and every other app you connect show up as its tools.

  • ChatGPT
  • OpenClaw
  • Hermes

    Add Cotlet to your agent

    Claude Code
    claude mcp add --transport http cotlet \
  https://cotlet.dev/mcp/v1 \
  --header "Authorization: Bearer $COTLET_API_KEY"
    Cursor
    {

      "url": "https://cotlet.dev/mcp/v1",
      "headers": {
        "Authorization": "Bearer ${COTLET_API_KEY}"
      }
    }
  }
}
    Codex
    # ~/.codex/config.toml
[mcp_servers.cotlet]
url = "https://cotlet.dev/mcp/v1"
bearer_token_env_var = "COTLET_API_KEY"

    Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.

For scripts: REST API

Every tool is an endpoint under /api/v1/timetastic with its own method and path, such as POST /api/v1/timetastic/time-offs, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the Timetastic API and MCP server do?

9 tools on your own Timetastic account. Agents call them as operations of the MCP tools timetastic_read and timetastic_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Security overview

How much do the Timetastic API and MCP server cost?

One price for both: a tool call costs the same over MCP or REST. Free 7-day trial with 2,000 credits, no card needed. Then one-time credit packs, no subscription, valid 12 months. Most calls use 25 credits, and your Cloud Browser uses 50 credits a day while Timetastic is enabled for agents, so 20 calls a day come to 550 credits.

Questions

Does Timetastic have an API?

Yes, Timetastic has a REST API with a bearer token, and no official MCP server (checked 20 Oct 2026). Only admin users can get a token, and the API has no endpoints for the monthly and annual summary reports.

How do I get access?

Sign up free, open Timetastic under Integrations in the console and press Request access. Your free trial starts with your account, no card needed.

Is the MCP server different from the API?

No, only the way in. Cotlet builds each integration as a REST API and puts an MCP server on top, so both have the same 9 tools, the same inputs and answers, one API key and one price. AI agents such as Claude, ChatGPT or Cursor use MCP; scripts, cron jobs and HTTP steps in n8n, Make or Zapier use the REST API.

What is the Cloud Browser?

Your own Chrome that Cotlet runs for you in the EU, around the clock. You open it from the console, sign in to Timetastic yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so Timetastic sees the browser you signed in with. Password saving is off and the profile is stored encrypted with AES-256-GCM.

Can my agent act without asking me?

Not on anything that reaches other people: book_time_off, approve_request, decline_request, cancel_booking wait for your OK by default. You can switch that off per tool for scheduled runs.

Do I need to be a Timetastic admin?

No. Timetastic gives an API token only to admin users, while Cotlet works in your own account with your own role (source: Timetastic Help, Timetastic API). An approver approves, an employee books their own leave, and the reports need an account that can open Settings > Reporting & Backup.

Can my agent override a staffing limit?

Only when you allow it. A department's Maximum absent limit blocks an employee booking for themselves, and shows a manager or admin a warning they can override with Confirm (source: Timetastic Help, Maximum absent). book_time_off stops at that warning unless confirm_override is true.

Should I use a Timetastic MCP server from GitHub instead?

Pick one if you want the code on your own computer and do not mind the upkeep: you install it, sign it in and fix it when Timetastic changes. Pick Cotlet if you want it hosted and kept working for you.

Can I use it in n8n, Make or Zapier?

Yes. Add https://cotlet.dev/mcp/v1 in n8n's MCP Client node, or call the REST endpoints from an HTTP step in Make or Zapier.

Who runs Cotlet?

Cotlet is run by Take Group, a Polish software company working since 2019. Take Group runs about 3,200 websites on its own systems and has its own DevOps team for infrastructure security. We built and used integrations like this inside the company for years before opening them as Cotlet.

Is Cotlet affiliated with Timetastic?

No. Cotlet is independent and not affiliated with Timetastic.
