Privacy & Analytics

Weather MCP is committed to protecting your privacy while providing optional analytics to help improve the service.

Privacy First Philosophy

Analytics are completely optional and disabled by default.

  • No tracking unless you explicitly opt in
  • No personal data collected
  • No location data stored
  • Fully transparent about what we collect
  • Open source - audit the code yourself

What We Collect (If Analytics Enabled)

When you enable analytics by setting ENABLE_ANALYTICS=true, Weather MCP collects:

Tool Usage Statistics

  • Tool name (e.g., "get_forecast", "get_current_conditions")
  • Call count (how many times each tool is called)
  • Success/failure status (whether the call succeeded)
  • Response time (how long the request took)

Error Information

  • Error type (e.g., "API_ERROR", "LOCATION_NOT_FOUND")
  • Error count (how many times each error occurs)
  • Affected tools (which tools encounter which errors)

System Information

  • Weather MCP version (e.g., "1.2.3")
  • Anonymous installation ID (randomly generated UUID)
  • Provider used (NOAA or Open-Meteo)

Performance Metrics

  • Cache hit rate (how often cached data is used)
  • Average response times (performance metrics)

What We DON'T Collect

The following are never collected:

  • ❌ Location names or coordinates you search
  • ❌ Weather data requests or responses
  • ❌ IP addresses
  • ❌ User identifiers (beyond anonymous installation ID)
  • ❌ Timestamps precise enough to track usage patterns
  • ❌ Claude conversation content
  • ❌ Personal information of any kind

How Analytics Help

The anonymous analytics data helps us:

  1. Identify Popular Features - Know which tools are most used
  2. Detect Problems - Find error patterns to fix
  3. Improve Performance - Optimize slow operations
  4. Plan Development - Prioritize new features
  5. Ensure Reliability - Monitor success rates

Enabling Analytics

To enable analytics, add to your Claude Desktop configuration:

{
  "mcpServers": {
    "weather": {
      "command": "weather-mcp",
      "env": {
        "ENABLE_ANALYTICS": "true"
      }
    }
  }
}

Disabling Analytics

Analytics are disabled by default. To ensure they're disabled:

  1. Remove ENABLE_ANALYTICS from your configuration, or
  2. Set ENABLE_ANALYTICS: "false"

Changes take effect after restarting Claude Desktop.

Data Transmission

How Data is Sent

  • Batched: Events are collected and sent in batches
  • Async: Never blocks weather requests
  • Encrypted: HTTPS for all transmissions
  • Reliable: Queued if network unavailable

Where Data Goes

  • Analytics Server: analytics.weather-mcp.dev
  • Storage: Aggregated in anonymized databases
  • Access: Only Weather MCP maintainers

Data Retention

  • Raw Events: 90 days
  • Aggregated Statistics: Indefinitely
  • Installation IDs: Stored but not linked to users

Public Analytics Dashboard

All analytics data is publicly available at:

weather-mcp.dev/dashboard

You can see:

  • Total API calls
  • Success rates
  • Popular tools
  • Performance metrics
  • Error rates

Technical Implementation

Installation ID

When analytics are enabled, Weather MCP generates a random UUID on first run:

Installation ID: 550e8400-e29b-41d4-a716-446655440000

This ID:

  • Is random (not based on any user data)
  • Is local (stored on your machine only)
  • Cannot identify you (no personal information)
  • Allows deduplication (counts unique installations)

Data Schema

Example analytics event:

{
  "installation_id": "550e8400-e29b-41d4-a716-446655440000",
  "version": "1.2.3",
  "event_type": "tool_call",
  "tool_name": "get_forecast",
  "success": true,
  "response_time_ms": 423,
  "provider": "noaa",
  "error_type": null,
  "timestamp": "2025-11-12T12:00:00Z"
}

Notice what's NOT included:

  • No location data
  • No weather query details
  • No user identification
  • No precise timing
