Environment Variables

Example Workflows

Import customers from a spreadsheet

"Here's my customer list: Acme Corp (VAT: BE0123456789, Brussels), Widget Inc (Amsterdam)..."

The AI will use create_customers_bulk to import them all at once.

Track time

"Start a timer for Acme Corp on the Consulting service"

Uses list_customers → list_services → start_timer.

"Stop my running timer"

Uses get_running_timers → stop_timer.

Create an invoice

"Create an invoice for Acme Corp for all uninvoiced work"

Uses get_uninvoiced_entries → create_invoice (as Draft).

Dashboard overview

"How many hours did I track this month? What's my outstanding revenue?"

Uses get_dashboard_stats.

Development

git clone https://github.com/user/tiktak-mcp-server.git
cd tiktak-mcp-server
npm install
npm run dev  # requires TIKTAK_API_KEY env var

Testing with MCP Inspector

API Key Security

• API keys are created in the TikTak app by Admin or Owner users

• Keys use the tk_ prefix and are hashed (SHA256) server-side

• The full key is shown only once at creation — store it securely

• Keys can be revoked anytime in the TikTak app

• Rate limits apply per key (based on your plan tier)
