Get list of available backups
AI agents call get_backups to retrieve information from HC3 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves or queries data (list of backups) with no side effects. It is a read-only operation that does not create, modify, delete, or execute any actions. Even in a smart home system context, simply listing backups poses minimal security risk as it only exposes metadata about backup availability, not the backup contents themselves or system control capabilities.
From the tool's definition Tool name 'get_backups' and description 'Get list of available backups' indicate a query operation that retrieves information about existing backups without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Get list of available backups. It is categorised as a Read tool in the HC3 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HC3 MCP Server MCP server in PolicyLayer and add a rule for get_backups: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches HC3 MCP Server. Nothing to install.
get_backups is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_backups rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_backups. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_backups is provided by the HC3 MCP Server MCP server (jangabrielsson/hc3_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
