MCP for Unity Telemetry

MCP for Unity includes privacy-focused, anonymous telemetry to help us improve the product. This document explains what data is collected, how to opt out, and our privacy practices.

🔒 Privacy First

Anonymous: We use randomly generated UUIDs - no personal information
Non-blocking: Telemetry never interferes with your Unity workflow
Easy opt-out: Simple environment variable or Unity Editor setting
Transparent: All collected data types are documented here

📊 What We Collect

Usage Analytics

Tool Usage: Which MCP tools you use (manage_script, manage_scene, etc.)
Performance: Execution times and success/failure rates
System Info: Unity version, platform (Windows/Mac/Linux), MCP version
Milestones: First-time usage events (first script creation, first tool use, etc.)

Technical Diagnostics

Connection Events: Bridge startup/connection success/failures
Error Reports: Anonymized error messages (truncated to 200 chars)
Server Health: Startup time, connection latency

What We DON'T Collect

❌ Your code or script contents
❌ Project names, file names, or paths
❌ Personal information or identifiers
❌ Sensitive project data
❌ IP addresses (beyond what's needed for HTTP requests)

🚫 How to Opt Out

Method 1: Environment Variable (Recommended)

Set any of these environment variables to true:

bash

# Disable all telemetry
export DISABLE_TELEMETRY=true

# MCP for Unity specific
export UNITY_MCP_DISABLE_TELEMETRY=true

# MCP protocol wide  
export MCP_DISABLE_TELEMETRY=true

Method 2: Unity Editor (Coming Soon)

In Unity Editor: Window > MCP for Unity > Settings > Disable Telemetry

Method 3: Manual Config

Add to your MCP client config:

json

{
  "env": {
    "DISABLE_TELEMETRY": "true"
  }
}

🔧 Technical Implementation

Architecture

Python Server: Core telemetry collection and transmission
Unity Bridge: Local event collection from Unity Editor
Anonymous UUIDs: Generated per-installation for aggregate analytics
Thread-safe: Non-blocking background transmission
Fail-safe: Errors never interrupt your workflow

Data Storage

Telemetry data is stored locally in:

Windows: %APPDATA%\UnityMCP\
macOS: ~/Library/Application Support/UnityMCP/
Linux: ~/.local/share/UnityMCP/

Files created:

customer_uuid.txt: Anonymous identifier
milestones.json: One-time events tracker

Data Transmission

Endpoint: https://api-prod.coplay.dev/telemetry/events
Method: HTTPS POST with JSON payload
Retry: Background thread with graceful failure
Timeout: 10 second timeout, no retries on failure

📈 How We Use This Data

Product Improvement

Feature Usage: Understand which tools are most/least used
Performance: Identify slow operations to optimize
Reliability: Track error rates and connection issues
Compatibility: Ensure Unity version compatibility

Development Priorities

Roadmap: Focus development on most-used features
Bug Fixes: Prioritize fixes based on error frequency
Platform Support: Allocate resources based on platform usage
Documentation: Improve docs for commonly problematic areas

What We Don't Do

❌ Sell data to third parties
❌ Use data for advertising/marketing
❌ Track individual developers
❌ Store sensitive project information

🛠️ For Developers

Custom Telemetry Events

python

core.telemetry import record_telemetry, RecordType

record_telemetry(RecordType.USAGE, {
    "custom_event": "my_feature_used",
    "metadata": "optional_data"
})

Telemetry Status Check

python

core.telemetry import is_telemetry_enabled

if is_telemetry_enabled():
    print("Telemetry is active")
else:
    print("Telemetry is disabled")

📋 Data Retention Policy

Aggregated Data: Retained indefinitely for product insights
Raw Events: Automatically purged after 90 days
Personal Data: None collected, so none to purge
Opt-out: Immediate - no data sent after opting out

🤝 Contact & Transparency

Questions: Discord Community
Issues: GitHub Issues
Privacy Concerns: Create a GitHub issue with "Privacy" label
Source Code: All telemetry code is open source in this repository

📊 Example Telemetry Event

Here's what a typical telemetry event looks like:

json

{
  "record": "tool_execution",
  "timestamp": 1704067200,
  "customer_uuid": "550e8400-e29b-41d4-a716-446655440000", 
  "session_id": "abc123-def456-ghi789",
  "version": "3.0.2",
  "platform": "posix",
  "data": {
    "tool_name": "manage_script",
    "success": true,
    "duration_ms": 42.5
  }
}

Notice:

✅ Anonymous UUID (randomly generated)
✅ Tool performance metrics
✅ Success/failure tracking
❌ No code content
❌ No project information
❌ No personal data
