What reach_segments_list does on Hostinger
AI agents call reach_segments_list to retrieve information from Hostinger without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why reach_segments_list is rated Low
This tool retrieves and displays existing contact segment data without modifying, deleting, or executing any operations. It is a straightforward data query operation. The blast radius of misuse is minimal—an attacker could see segment metadata but cannot alter customer data, delete segments, or trigger financial transactions.
From the tool's definition Tool name contains 'list' and description states 'List contact segments', which are retrieval operations with no side effects.
Attacks that exploit this kind of access
The rule that runs reach_segments_list safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hostinger, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For reach_segments_list, this is the rule to start with:
reach_segments_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Hostinger, apply this rule, and every reach_segments_list call is checked against it from then on.
