It performs no writes, deletions, executions, or financial operations. The blast radius of misuse is minimal — an agent calling it repeatedly would only retrieve read-only schema/configuration information. Classification as Read is appropriate. From the tool's own definition: "Tool name contains 'list' and description states it 'List all available association types' — a pure retrieval operation with no data modification, deletion, or side effects." ## Use case AI agents call crm_list_association_types to retrieve information from HubSpot MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches HubSpot MCP: ```json { "version": "1", "default": "deny", "tools": { "crm_list_association_types": {} } } ``` ## Other tools on HubSpot MCP (110) - `calls_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/calls-archive.md - `calls_batch_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/calls-batch-archive.md - `crm_batch_delete_associations` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-batch-delete-associations.md - `crm_batch_delete_objects` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-batch-delete-objects.md - `crm_delete_association` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-delete-association.md - `crm_delete_object` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-delete-object.md - `emails_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/emails-archive.md - `emails_batch_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/emails-batch-archive.md - `engagement_details_delete` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/engagement-details-delete.md - `meetings_batch_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/meetings-batch-archive.md - `meetings_delete` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/meetings-delete.md - `notes_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/notes-archive.md - `notes_batch_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/notes-batch-archive.md - `products_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/products-archive.md - `products_batch_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/products-batch-archive.md - `tasks_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/tasks-archive.md - `tasks_batch_archive` — Destructive — https://policylayer.com/tools/blacksand-software-hubspot-mcp/tasks-batch-archive.md - `calls_batch_read` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/calls-batch-read.md - `calls_get` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/calls-get.md - `calls_list` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/calls-list.md - `calls_search` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/calls-search.md - `communications_get_preferences` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/communications-get-preferences.md - `communications_get_subscription_definitions` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/communications-get-subscription-definitions.md - `communications_get_subscription_status` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/communications-get-subscription-status.md - `crm_get_associations` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-get-associations.md - `crm_get_company` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-get-company.md - `crm_get_company_properties` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-get-company-properties.md - `crm_get_contact` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-get-contact.md - `crm_get_contact_properties` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-get-contact-properties.md - `crm_get_lead` — Read — https://policylayer.com/tools/blacksand-software-hubspot-mcp/crm-get-lead.md - …and 80 more: https://policylayer.com/tools/blacksand-software-hubspot-mcp.md ## For agents This record is a snapshot.
