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.
All telemetry is optional and can be disabled at any time. See the Opt-Out section below.

​
What We Collect

We collect the following anonymous data:
A hashed identifier derived from your machine characteristics. No personal information is included in this hash.
  • Which MCP tools are used
  • Performance metrics (execution time, success/failure)
  • Frequency of tool invocations
  • Sanitized workflow structures (all sensitive data removed)
  • Node type usage patterns
  • Workflow complexity metrics
  • Categories of errors encountered
  • No error messages with user data
  • Stack trace patterns (sanitized)
  • Platform (Linux, macOS, Windows)
  • Architecture (x64, arm64)
  • Node.js version
  • n8n-MCP version

​
What We DON’T Collect

We take your privacy seriously. The following information is NEVER collected:
  • ❌ 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:
1

URL Redaction

URLs are replaced with [URL] or [REDACTED]
2

Key Detection

Long alphanumeric strings (potential keys) are replaced with [KEY]
3

Email Removal

Email addresses are replaced with [EMAIL]
4

Auth Stripping

Authentication-related fields are completely removed

​
Data Storage

Secure Storage

Data is stored securely using Supabase with encryption

Write-Only Access

Anonymous users have write-only access (cannot read data back)

Row Level Security

RLS policies prevent data access by anonymous users

No Personal Data

No personal identification is possible from collected data

​
Opt-Out

You can disable telemetry at any time: 
# Disable telemetry
npx n8n-mcp telemetry disable

# Re-enable telemetry
npx n8n-mcp telemetry enable

# Check status
npx n8n-mcp telemetry status

​
Data Usage

Collected data is used solely to:

Feature Usage

Understand which features are most used

Error Patterns

Identify common error patterns

Performance

Improve tool performance and reliability

Development Priorities

Guide development priorities

​
Machine Learning

All ML training uses sanitized, anonymized data only.
We may use collected data to train machine learning models for:
  • Workflow generation suggestions
  • Common pattern detection
  • Error prediction and prevention
Users can opt-out at any time with npx n8n-mcp telemetry disable.

​
Data Retention

  • Data is retained for analysis purposes
  • No time-based deletion policy (data is already anonymized)
  • No personal identification is possible from the collected data

​
Privacy Commitment

Our Promise

We are committed to:
  • Collecting only anonymous, sanitized data
  • Providing easy opt-out mechanisms
  • Being transparent about data usage
  • Never selling or sharing user data
  • Continuously improving privacy protections
