Get all users and groups with access to Veeam Backup & Replication.
AI agents call ViewAllUsers to retrieve information from Veeam VBR v13 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user and group information without modifying, deleting, or executing operations. It is a read-only query. However, the severity is elevated to medium because the result reveals access control configuration of a critical backup infrastructure, which could enable attackers to identify high-privileged accounts or social engineering targets.
From the tool's definition Tool name 'ViewAllUsers' and description 'Get all users and groups with access to Veeam Backup & Replication' indicate a query/retrieval operation with no side effects.

Register the Veeam VBR v13 MCP Server MCP server in PolicyLayer and add a rule for ViewAllUsers: 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 Veeam VBR v13 MCP Server. Nothing to install.
ViewAllUsers 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 ViewAllUsers 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 ViewAllUsers. 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.
ViewAllUsers is provided by the Veeam VBR v13 MCP Server MCP server (kid-boy/veeam-mcp-13). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
