Propalt Developer, API & MCP Terms

Effective date: 27 May 2026  |  Last updated: 27 May 2026  |  Jurisdiction: England & Wales

These Propalt Developer, API & MCP Terms apply when authenticated Propalt users access or use Propalt developer tools, APIs, Model Context Protocol integrations, GPT Actions, OAuth integrations, API keys, developer documentation, or AI-enabled developer interfaces. These terms supplement the main Propalt Terms and Conditions. Where these terms differ from the main Terms and Conditions, these terms apply to developer, API, MCP, GPT Action, OAuth, and AI-enabled integration activity. By accessing or using Propalt developer tools, APIs, MCP integrations, GPT Actions, or related services, you agree to these terms.

2. Scope of these terms

• the Propalt developer portal;
• Propalt APIs;
• Propalt API documentation;
• Propalt MCP servers and tools;
• GPT Actions or AI assistant integrations connected to Propalt;
• OAuth-authorised integrations;
• API keys, bearer tokens, access tokens, or other credentials issued by Propalt;
• automated workflows, agents, or applications that call Propalt services; and
• any data, responses, outputs, summaries, classifications, estimates, analytics, or other content returned by Propalt through those services.

These terms apply to authenticated Propalt users only. Propalt developer tools, APIs, and MCP integrations are not intended for unauthenticated public use.

3. Relationship with other terms

• the main Propalt Terms and Conditions;
• the Propalt Privacy Policy;
• the Propalt MCP & AI Integrations Privacy Notice;
• any order form, subscription agreement, commercial agreement, or service agreement between you and Propalt;
• any applicable API documentation, technical documentation, usage rules, or acceptable-use guidance published by Propalt.

If there is a conflict between these terms and a signed written agreement between you and Propalt, the signed written agreement will take priority to the extent of the conflict.

4. Access and eligibility

Propalt APIs, MCP integrations, GPT Actions, and developer tools are available only to authorised users with a valid Propalt account, subscription, licence, trial, or written permission from Propalt.

• you are not authorised to do so;
• your access has been suspended, revoked, or terminated;
• you are acting on behalf of an organisation without authority;
• your use would breach applicable law or regulation;
• your use would breach these terms or any agreement with Propalt.

You are responsible for ensuring that all users, employees, contractors, agents, systems, and applications accessing Propalt services through your account comply with these terms.

5. Accounts, credentials, and security

Propalt may provide access through API keys, bearer tokens, OAuth tokens, account credentials, or other authentication methods.

• keeping credentials secure;
• limiting access to authorised personnel only;
• rotating, revoking, or replacing credentials where appropriate;
• promptly notifying Propalt of suspected unauthorised access;
• ensuring credentials are not exposed in prompts, public repositories, client-side code, browser-exposed environments, logs, screenshots, or insecure systems;
• ensuring integrations are configured securely;
• disconnecting or revoking access when an integration is no longer required.

OAuth tokens, API keys, bearer tokens, and similar credentials are encrypted at rest by Propalt.

You must not share, sell, transfer, publish, or disclose credentials except as expressly permitted by Propalt.

You are responsible for all activity carried out using credentials issued to you or your organisation, unless the activity results from Propalt's own breach of these terms.

6. OAuth and connected integrations

Where Propalt supports OAuth or similar authorisation flows, you may connect Propalt services to supported third-party platforms, including AI assistant platforms, only where you are authorised to do so.

• reviewing the permissions requested by the integration;
• ensuring the integration is appropriate for your organisation's use;
• revoking access when no longer required;
• complying with the third-party platform's terms and policies;
• ensuring that users understand that requests and responses may pass through the relevant third-party platform.

Propalt may revoke, restrict, rotate, or require re-authorisation of OAuth access where reasonably necessary for security, misuse prevention, legal compliance, service integrity, or account management.

Non-public information made available through Propalt developer services, documentation, credentials, dashboards, support channels, or technical communications must be treated as confidential.

You must not disclose confidential information to third parties except where authorised by Propalt, required by law, or necessary for your authorised internal use.
