Adds zero-configuration anonymous usage statistics to track: - Number of active users with deterministic user IDs - Which MCP tools AI agents use most - What workflows are built (sanitized to protect privacy) - Common errors and issues Key features: - Zero-configuration design with hardcoded write-only credentials - Privacy-first approach with comprehensive data sanitization - Opt-out support via config file and environment variables - Docker-friendly with environment variable support - Multi-process safe with immediate flush strategy - Row Level Security (RLS) policies for write-only access Technical implementation: - Supabase backend with anon key for INSERT-only operations - Workflow sanitization removes all sensitive data - Environment variables checked for opt-out (TELEMETRY_DISABLED, etc.) - Telemetry enabled by default but respects user preferences - Cleaned up all debug logging for production readiness 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# Privacy Policy for n8n-mcp Telemetry
|
|
|
|
## Overview
|
|
n8n-mcp collects anonymous usage statistics to help improve the tool. This data collection is designed to respect user privacy while providing valuable insights into how the tool is used.
|
|
|
|
## What We Collect
|
|
- **Anonymous User ID**: A hashed identifier derived from your machine characteristics (no personal information)
|
|
- **Tool Usage**: Which MCP tools are used and their performance metrics
|
|
- **Workflow Patterns**: Sanitized workflow structures (all sensitive data removed)
|
|
- **Error Types**: Categories of errors encountered (no error messages with user data)
|
|
- **System Information**: Platform, architecture, Node.js version, and n8n-mcp version
|
|
|
|
## What We DON'T Collect
|
|
- Personal information or usernames
|
|
- API keys, tokens, or credentials
|
|
- URLs, endpoints, or hostnames
|
|
- Email addresses or contact information
|
|
- File paths or directory structures
|
|
- Actual workflow data or parameters
|
|
- Database connection strings
|
|
- Any authentication information
|
|
|
|
## Data Sanitization
|
|
All collected data undergoes automatic sanitization:
|
|
- URLs are replaced with `[URL]` or `[REDACTED]`
|
|
- Long alphanumeric strings (potential keys) are replaced with `[KEY]`
|
|
- Email addresses are replaced with `[EMAIL]`
|
|
- Authentication-related fields are completely removed
|
|
|
|
## Data Storage
|
|
- Data is stored securely using Supabase
|
|
- Anonymous users have write-only access (cannot read data back)
|
|
- Row Level Security (RLS) policies prevent data access by anonymous users
|
|
|
|
## Opt-Out
|
|
You can disable telemetry at any time:
|
|
```bash
|
|
npx n8n-mcp telemetry disable
|
|
```
|
|
|
|
To re-enable:
|
|
```bash
|
|
npx n8n-mcp telemetry enable
|
|
```
|
|
|
|
To check status:
|
|
```bash
|
|
npx n8n-mcp telemetry status
|
|
```
|
|
|
|
## Data Usage
|
|
Collected data is used solely to:
|
|
- Understand which features are most used
|
|
- Identify common error patterns
|
|
- Improve tool performance and reliability
|
|
- Guide development priorities
|
|
|
|
## Data Retention
|
|
- Data is retained for analysis purposes
|
|
- No personal identification is possible from the collected data
