- Let Breeze agents search across your Slack channels to find relevant conversations
- Give agents access to your Slack message history so they can pull context directly into your HubSpot workflows
- Keep your team's Slack knowledge accessible to AI agents when you need it — for research, summaries, or cross-referencing with CRM dataBreeze is an AI and can make mistakes. It may misinterpret messages, miss context, or return incomplete or inaccurate results when searching your Slack data.

General

Privacy & data governance

Data retention policy

Customer data is retained for as long as you remain an active customer. The HubSpot platform provides active customers with the tools to delete their data, as they see fit. Former customers’ data is removed from live databases upon a customer’s written request or after an established period following the termination of all customer agreements. Freemium customers’ data is purged when the portal is no longer actively used, and former paying customers’ data is purged 90 days after all customer relationships are terminated. Information stored in replicas, snapshots, and backups is not actively purged but instead naturally ages itself from the repositories as the data lifecycle occurs. HubSpot retains certain data like logs and related metadata in order to address security, compliance, or statutory needs. Please see https://www.hubspot.com/security for more info.

Data storage policy

HubSpot products are hosted with cloud infrastructure providers with SOC 2 Type II and ISO 27001 certifications, among others. The certified protections include dedicated security staff, strictly managed physical access control, and video surveillance. Access to the data stores is assigned to a limited to a small set of HubSpot employees based on their roles, and access is limited to the individuals who need it in order to respond to customer support and related requests.

Data hosting details

HubSpot does not store Slack data. The HubSpot MCP connector acts as a secure proxy between HubSpot Breeze AI agents and Slack's official MCP server (mcp.slack.com). When a user's Breeze agent needs to search or read Slack data, HubSpot's MCP gateway forwards the authenticated request to Slack's MCP API in real time and returns the response to the agent. All communication occurs over HTTPS.
