Model Context Protocol (MCP) Integration Addendum

Last Updated: 24 June 2025

This Model Context Protocol Integration Addendum ("Addendum") is incorporated into and forms a part of the Marketingmary Terms of Service ("Terms") and, where applicable, the Data Processing Agreement ("DPA") between Marketingmary Ltd. ("we," "us," "our") and the customer organisation ("you," "your," "Organisation").

This Addendum governs your use of any third-party software, applications, or services that you choose to connect to your Marketingmary account ("MCP Integrations"). By enabling or using any MCP Integration, you agree to the terms of this Addendum.

1. DEFINITIONS

1.1. "MCP Integration" means a connection, enabled by you, that allows for the transfer of data between the Marketingmary Service and a Third-Party Service.

1.2. "Third-Party Service" means any external software, application, or platform that is not provided by Marketingmary but which you choose to connect to the Service via an MCP Integration.

2. SCOPE AND ACTIVATION

2.1. Client Control. The Marketingmary Service provides you with the technical capability to enable MCP Integrations. You have sole discretion and control over which Third-Party Services you connect to your account. All MCP Integrations are disabled by default and must be explicitly enabled by your organisation's authorised administrator on an opt-in basis.

2.2. Separate Credentials. Each MCP Integration requires you to provide your own credentials for the relevant Third-Party Service. These credentials will be isolated and used exclusively for your organisation's integration.

3. DATA PROCESSING & YOUR RESPONSIBILITIES

3.1. Instruction to Transfer. When you enable an MCP Integration, you are instructing Marketingmary to act as your agent to transfer your User Content and/or AI Output ("Your Data") to the selected Third-Party Service. You acknowledge that once Your Data is transferred, its subsequent processing, storage, and security are governed entirely by the terms, privacy policies, and security practices of the provider of that Third-Party Service.

3.2. Your Relationship with Third Parties. You are solely responsible for establishing and maintaining your own legal agreements, including any necessary data processing agreements, with the providers of any Third-Party Services you use. Marketingmary is not a party to, and has no obligations under, any such agreements. You hereby warrant that you have all necessary rights, permissions, and a valid legal basis under applicable Data Protection Laws to instruct Marketingmary to transfer Your Data to any enabled Third-Party Service.

3.3. Revoking Access. You may revoke access for any MCP Integration at any time through your account settings. Upon revocation, Marketingmary will cease transferring Your Data to that Third-Party Service. You acknowledge that this will not affect any of Your Data that has already been transferred.

3.4. Data Protection Roles. The parties agree that in respect of any Personal Data contained within Your Data: (a) Marketingmary remains your Processor under the main DPA for the act of transferring the data to the Third-Party Service upon your instruction; and (b) upon successful delivery of the data, the provider of the Third-Party Service acts as a separate processor or controller as determined by your agreement with them, and Marketingmary has no further obligations for that data.

4. DISCLAIMER & LIMITATION OF LIABILITY

4.1. NO WARRANTY. MCP INTEGRATIONS AND THIRD-PARTY SERVICES ARE NOT PART OF THE MARKETINGMARY SERVICE. THEY ARE PROVIDED "AS IS," AND WE MAKE NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, REGARDING THEIR PERFORMANCE, SECURITY, RELIABILITY, OR COMPLIANCE WITH ANY APPLICABLE LAWS.

4.2. LIMITATION OF LIABILITY. MARKETINGMARY SHALL HAVE NO LIABILITY WHATSOEVER FOR ANY ACTS OR OMISSIONS OF ANY THIRD-PARTY SERVICE PROVIDER, OR FOR ANY DAMAGE, LOSS, OR HARM ARISING FROM OR IN CONNECTION WITH YOUR USE OF ANY MCP INTEGRATION OR THIRD-PARTY SERVICE. THIS INCLUDES, BUT IS NOT LIMITED TO, ANY DATA BREACH, SERVICE UNAVAILABILITY, DATA LOSS, OR NON-COMPLIANCE WITH DATA PROTECTION LAWS CAUSED BY THE THIRD-PARTY SERVICE.

5. INDEMNIFICATION

You agree to defend, indemnify, and hold Marketingmary harmless from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising from or in connection with: (a) your use of any MCP Integration; (b) any breach of your warranties under this Addendum; or (c) any claims brought against Marketingmary by a third party related to the transfer or processing of Your Data by a Third-Party Service provider you have enabled.

6. AUDIT & TRANSPARENCY

Marketingmary will maintain an audit trail of all MCP activities initiated from your account, detailing which integrations were enabled and when data transfers were instructed. We will provide clear documentation within the Service regarding the general data flows for each available MCP Integration to help you make informed decisions.

7. GENERAL

This Addendum is governed by the laws and jurisdiction set out in the Marketingmary Terms of Service. In the event of a conflict between this Addendum and the Terms regarding the subject matter herein, this Addendum shall prevail.
