TLA X-MCP Terms of Use

Last updated: 5 November 2026

1. About TLA X-MCP

TLA X-MCP is an internal application operated by Trayler Lane Accountancy Limited.

The application is designed to provide authorised users with access to permitted Xero accounting information through Microsoft 365 and related Microsoft services.

2. Authorised use

TLA X-MCP may only be used:

• by persons authorised by Trayler Lane;

• for legitimate business and professional purposes;

• in relation to Xero organisations for which appropriate authority and access have been granted; and

• in accordance with Trayler Lane’s internal information security, confidentiality and data protection requirements.

3. Xero authorisation

Users must have appropriate authority before connecting a Xero organisation to TLA X-MCP.

Xero requires third-party integrations to be authorised by a user and uses OAuth 2.0 so that applications can receive authorised access without the user’s Xero password being provided to the integration. [developer.xero.com], [central.xero.com]

Users must not attempt to access an organisation, accounting record or other information which they are not authorised to access.

4. Permitted use

TLA X-MCP may be used for purposes including:

• accounting analysis;

• reconciliations;

• management accounts and financial reporting;

• VAT and tax-related analysis;

• transaction investigation;

• preparation of accounting working papers; and

• other legitimate services performed by Trayler Lane.

5. Professional judgement

Information produced or summarised using TLA X-MCP is an aid to professional work.

Outputs generated through Microsoft 365 Copilot, artificial intelligence or other automated processing must not be assumed to be complete or accurate solely because they have been produced by the application.

Where information is used for accounts, tax returns, VAT returns, regulatory submissions, professional advice or other material decisions, an appropriately authorised person should review the underlying information and exercise professional judgement before relying on it.

6. Changes to accounting data

Unless specifically authorised and appropriately controlled, TLA X-MCP should be used on a read-only basis.

Users must not use the application to create, amend, delete or post accounting records in Xero unless the relevant functionality has been expressly approved by Trayler Lane and appropriate review and authorisation procedures are in place.

7. Confidentiality

Information accessed using TLA X-MCP may contain confidential client and third-party information.

Users must:

• protect such information from unauthorised access;

• use it only for legitimate professional purposes;

• not disclose credentials, tokens or other authentication information;

• comply with applicable confidentiality obligations; and

• follow Trayler Lane’s security and data protection procedures.

8. Third-party services

TLA X-MCP relies on third-party services, including Xero and Microsoft 365.

Availability and functionality may therefore depend on those services. Trayler Lane does not control the continued availability or functionality of third-party platforms.

9. No guarantee of uninterrupted availability

TLA X-MCP may be modified, suspended or withdrawn at any time.

No guarantee is given that the application will be continuously available, error-free or suitable for every accounting or reporting purpose.

10. Security

Users must take reasonable steps to maintain the security of their Microsoft and Xero accounts, including protecting login credentials and complying with applicable multi-factor authentication and organisational security requirements.

Suspected unauthorised access or compromise should be reported promptly through Trayler Lane’s normal security procedures.

11. Privacy

Use of TLA X-MCP is subject to the TLA X-MCP Privacy Notice.

12. Changes to these terms

Trayler Lane may update these Terms of Use to reflect changes to the application, Microsoft 365, Xero, applicable legislation or internal procedures.

The latest version will be published on the Trayler Lane website.
