stop_timer¶

Stop the currently running timer and automatically create a time entry for the tracked period.

Summary¶

The stop_timer tool ends any currently running timer in EARLY and automatically creates a time entry for the time that was tracked. This is the essential companion to start_timer and completes the real-time time tracking workflow.

Key Features: - Stops the currently active timer instantly - Automatically creates a time entry for the tracked period - No parameters needed - works with whatever timer is running - Handles minimum time requirements and edge cases - Provides detailed summary of the completed time session

Parameters¶

Usage Patterns¶

1. Simple Timer Stop¶

Stop the current timer (most common usage):

{
  // No parameters needed
}

2. Empty Object (Alternative)¶

Some MCP clients require an empty object:

{}

Both formats work identically and will stop the currently running timer.

Behavior¶

Timer Stop Process¶

1. Active Timer Detection: Checks for currently running timer
2. Timer Validation: Ensures timer has run for minimum required time
3. Authentication: Verifies API credentials with EARLY
4. Timer Termination: Stops the active timer via EARLY API v4
5. Time Entry Creation: Automatically creates time entry for the session
6. Response Summary: Returns details of the completed time session

Time Entry Creation¶

When a timer is stopped: - Start Time: Uses the time when start_timer was called - End Time: Uses the current time when stop_timer is called
- Duration: Calculates the elapsed time between start and stop - Activity: Uses the activity specified when starting the timer - Description: Uses the description provided when starting the timer (if any)

Minimum Time Requirements¶

EARLY has a minimum time requirement for timer sessions: - Minimum Duration: Timers must run for at least 1 minute - Sub-minute Sessions: Sessions under 1 minute are not saved as time entries - Graceful Handling: Short sessions receive appropriate feedback

Examples¶

Successful Timer Stop¶

After working for several hours:

{}

Response:

Timer stopped successfully!

Final Summary:
- Activity: Web Development  
- Description: Implementing user authentication system
- ID: timer_abc123

Time entry has been saved.

Short Session Stop¶

Stopping a timer that ran for less than 1 minute:

{}

Response:

Timer stopped.

Timer must run for at least 1 minute for the tracking to be saved.

No Active Timer¶

Attempting to stop when no timer is running:

{}

Response:

No active timer found to stop.

There is currently no timer running. Use `start_timer` to begin tracking time for an activity.

Timer Session Workflow¶

Complete Tracking Session¶

graph LR
    A[start_timer] --> B[Work Period]
    B --> C[stop_timer]
    C --> D[Time Entry]

    E[No Timer] --> F[start_timer]
    F --> B

Full Timer Workflow: 1. start_timer → Begin tracking with activity and description 2. Work Period → Timer runs in background while you work 3. stop_timer → End tracking and create time entry 4. Review → Time entry appears in EARLY and can be queried with get_time_entries

Task Switching¶

When switching between different tasks:

graph LR
    A[Task A Timer] --> B[stop_timer]
    B --> C[start_timer Task B]
    C --> D[Task B Timer]
    D --> E[stop_timer]

Task Switch Process: 1. stop_timer → End current task timer 2. start_timer → Begin new task timer
3. Continue work → New timer tracks different activity 4. stop_timer → End when switching again or finishing work

Error Scenarios¶

Common Scenarios and Responses¶

Example Error Responses¶

Authentication Error¶

{
  "content": [{
    "type": "text",
    "text": "Operation failed: Authentication failed\n\nDebug info:\n- API Key: Missing\n- API Secret: Present\n- Base URL: https://api.early.app"
  }]
}

No Active Timer¶

{
  "content": [{
    "type": "text",
    "text": "No active timer found to stop.\n\nThere is currently no timer running. Use `start_timer` to begin tracking time for an activity."
  }]
}

Related Tools¶

Essential Companion Tools¶

• start_timer - Required to begin timer sessions before stopping them
• list_activities - Get activity IDs for starting timers
• get_time_entries - Review time entries created from timer sessions
• edit_time_entry - Modify entries created from completed timer sessions

Alternative Approaches¶

• create_time_entry - Create time entries manually instead of using timers

Workflow Integration¶

    A[list_activities] --> B[start_timer]
    B --> C[stop_timer] 
    C --> D[Time Entry Created]
    C --> E[get_time_entries]
    E --> F[edit_time_entry]

    G[Task Switch] --> B
    H[End of Day] --> C

Timer-Based Time Tracking: 1. Setup: list_activities → Get available projects 2. Start Work: start_timer → Begin real-time tracking 3. Work Period: Focus on task while timer runs 4. End Session: stop_timer → Create time entry automatically 5. Review: get_time_entries → Check tracked time 6. Adjust: edit_time_entry → Make corrections if needed

Best Practices¶

Effective Timer Management¶

• Stop immediately: End timers as soon as you finish tasks or take breaks
• Regular stops: Don't let timers run overnight or during long breaks
• Consistent workflow: Make stopping timers part of your task completion routine
• End-of-day cleanup: Always stop active timers before ending work sessions

Time Accuracy¶

• Prompt stopping: Stop timers when actually finishing work, not hours later
• Break handling: Stop timers during lunch breaks or long interruptions
• Task boundaries: Stop timers when switching to different types of work
• Meeting transitions: Stop project timers when switching to meetings

Session Management¶

• Meaningful durations: Ensure timer sessions represent actual work periods
• Avoid micro-sessions: Don't start and immediately stop timers (under 1 minute)
• Context preservation: Remember what you were working on when reviewing stopped timers
• Review habits: Check created time entries for accuracy after stopping

Integration with Daily Workflow¶

• Task completion: Use timer stops as natural task completion markers
• Status updates: Stop timers when providing project status updates
• Transition rituals: Make timer stopping part of task switching routine
• Daily review: Stop all timers before reviewing daily time tracking

Error Prevention and Recovery¶

• Check for active timers: Verify timer state before starting new work sessions
• Handle short sessions: Be aware that very short timer sessions aren't saved
• Network awareness: Ensure stable connection when stopping important timers
• Credential maintenance: Keep API credentials valid for successful timer operations
