Terms of Service

Last Updated: November 17, 2025

1. Agreement to Terms

These Terms of Service ("Terms") constitute a legally binding agreement between you and Ai Advisors Romuald Członkowski ("we," "us," or "our") regarding your access to and use of the n8n-mcp hosted service, available at https://n8n-mcp.com(the "Service").

By accessing or using our Service, you agree to be bound by these Terms and our Privacy Policy. If you disagree with any part of these Terms, you may not access or use the Service.

Important: We reserve the right to modify these Terms at any time. We will notify you of material changes via email or through the Service. Your continued use of the Service after such modifications constitutes your acceptance of the updated Terms.

2. Description of Service

What We Provide

n8n-mcp is a hosted service that provides Model Context Protocol (MCP) access to n8n workflow automation capabilities. The Service allows you to:

• Create, read, update, and delete n8n workflows using natural language through AI assistants (Claude, Cursor, Windsurf, etc.)
• Search and explore n8n nodes and their documentation
• Access pre-built workflow templates from n8n.io library
• Validate workflow configurations before deployment
• Manage your n8n instance through MCP-compatible tools

Service Architecture

The Service operates as a bridge between MCP clients and your n8n instance:

• Multi-tenant backend: Hosted infrastructure that handles authentication, rate limiting, and API routing
• n8n instance connection: You provide your n8n instance credentials, which we encrypt and use to access your workflows on your behalf
• MCP protocol: Standardized interface for AI assistants to interact with external tools and data sources

Beta Status

The Service is currently in beta. This means:

• Features may be added, modified, or removed without notice
• Service availability may be interrupted for maintenance or updates
• We appreciate your feedback and bug reports to help improve the Service
• Pricing and subscription tiers may change as we transition out of beta

3. User Accounts and Registration

Account Creation

To use the Service, you must create an account by authenticating through one of our supported OAuth 2.1 providers:

• Email
• Google
• GitHub

By creating an account, you represent and warrant that:

• You are at least 18 years of age or the age of majority in your jurisdiction
• All information you provide is accurate, current, and complete
• You will maintain the accuracy of such information
• You have the legal capacity to enter into these Terms

Account Security

You are responsible for:

• Maintaining the confidentiality of your API keys
• All activities that occur under your account
• Immediately notifying us of any unauthorized access or security breaches
• Ensuring your n8n instance credentials remain secure

API Key Management: The Service generates unique API keys (format: nmcp_xxx...) that you configure in your MCP client. These keys are stored hashed (SHA-256) and cannot be recovered if lost. You can generate new keys at any time from your dashboard.

Account Deletion

You may delete your account at any time from your account settings. Upon deletion:

• Your user account and associated data will be immediately deleted
• Your API keys will be immediately revoked
• Your subscription (if any) will be canceled, and you will not be charged further
• 1-hour cooldown period: You cannot re-register with the same email for 1 hour (GDPR compliance requirement)
• Anonymous telemetry data will be deleted within 30 days (see Privacy Policy)
• We will provide you with a UUID to verify telemetry deletion (telemetry uses hashed user IDs that cannot be reverse-engineered)

Note: Stripe payment records may be retained for up to 7 years to comply with financial regulations.

4. Subscription Plans and Billing

IMPORTANT: "n8n", the n8n logo, and related marks are trademarks and intellectual property of n8n GmbH. We are NOT affiliated with, endorsed by, or sponsored by n8n GmbH.

n8n-mcp is an independent, third-party service that integrates with the n8n workflow automation platform. All rights to the "n8n" name, logo, and software belong to n8n GmbH.

• n8n.io: Official n8n service operated by n8n GmbH - https://n8n.io
• Our service: n8n-mcp hosted service (independent third-party integration)
• Relationship: No affiliation, partnership, or endorsement from n8n GmbH

Note: If you have questions about n8n (the workflow automation platform), please contact n8n GmbH directly. We cannot provide official support for n8n itself, only for our n8n-mcp integration service.

8. Third-Party Services and Content

Required for Workflow Management: Your n8n Instance

IMPORTANT: To manage n8n workflows with this Service, you must have your own n8n instance. You can still use other features of the Service without an n8n instance. Your n8n instance can be either:

• n8n Cloud: A paid cloud plan from n8n.io (recommended for ease of use)
• Self-hosted: Your own n8n installation on your infrastructure

How it works:

1. You configure our Service to connect to YOUR n8n instance (via API key)
2. Our Service communicates with YOUR n8n instance to manage workflows
3. YOUR n8n instance connects to third-party services (Slack, Google Sheets, Notion, etc.)

Note: We do NOT directly connect to third-party services. All integrations happen through YOUR n8n instance. You are responsible for configuring and managing your n8n instance and its connections to third-party services.

Third-Party Service Responsibilities

Your n8n instance's connections to third-party services (e.g., Slack, Google Sheets, Notion) are subject to:

• The third-party service's own terms of service and privacy policy
• Any API usage limits imposed by the third-party service
• Your own credentials and authentication with the third-party service
• Your n8n instance configuration and settings

We are not responsible for:

• The availability, reliability, or security of your n8n instance
• The availability, reliability, or security of third-party services
• Any data loss or damages caused by your n8n instance or third-party services
• Changes to third-party APIs that may break your workflows
• Third-party service pricing or billing issues
• n8n.io cloud plan pricing or billing (you contract directly with n8n.io)

Service Dependencies

The Service relies on the following third-party providers:

• n8n.io: Required for workflow management features (cloud or self-hosted) - Get n8n Cloud
• Auth0: User authentication and OAuth 2.1 providers
• Supabase: Database and user data storage
• Stripe: Payment processing and subscription management
• Hetzner: Infrastructure hosting (Germany)
• GitHub: Open-source package distribution

Outages or issues with these providers (including your n8n instance) may temporarily affect the Service. We will make reasonable efforts to notify you of planned maintenance for our infrastructure, but we cannot control third-party provider availability.

9. Service Availability and Support

Service Level

We strive to provide reliable service but make no guarantees regarding:

• Uptime or availability (no SLA provided for Free or Supporter tiers)
• Performance or response times
• Freedom from bugs or errors
• Compatibility with future versions of MCP clients or n8n

Beta Status: As a beta service, you should expect occasional disruptions, breaking changes, and feature instability. We recommend maintaining backups of critical workflows.

Maintenance and Updates

We may perform maintenance that temporarily interrupts the Service:

• Scheduled maintenance: We'll notify you at least 24 hours in advance when possible
• Emergency maintenance: May be performed without notice to address critical security or stability issues
• Deployments: Backend updates cause brief downtime; you may need to restart your MCP client after deployments

Support

IMPORTANT: This is a solo developer project. Support is provided on a best-effort basis only, with no guarantees whatsoever regarding:

• Response times (no SLA for any tier)
• Issue resolution timelines
• Availability or responsiveness
• Support capacity during high-volume periods

Recommended support channels (all tiers):

• GitHub Issues (preferred): github.com/czlonkowski/n8n-mcp/issues - Community-driven, public issue tracking
• Email (best-effort): support@n8n-mcp.com - No guaranteed response time

Note: Supporter and Enterprise tiers receive the same best-effort support as Free tier. Subscription pricing reflects infrastructure costs and development funding, not premium support levels.
