Retrieve all contacts that have a specific tag applied. Supports filtering by tag name or tag ID. Results are paginated.
AI agents call get_contacts_by_tag to retrieve information from Ontraport MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing contact data based on tag criteria and returns results without any side effects or data modification. It performs a filtered search operation typical of Read category tools. The low severity reflects minimal risk if misused by an AI agent—at worst, it exposes contact information already tagged in the system, with no ability to alter data, execute operations, or cause financial impact.
From the tool's definition Tool description states 'Retrieve all contacts' with filtering options and pagination. The verb 'retrieve' and absence of any modification language (create, update, delete) clearly indicates a read-only data retrieval operation.
