List mounts on a Linux host.
AI agents call linux_mounts to retrieve information from Velociraptor MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation retrieving system configuration data (mounted filesystems). It has no side effects, does not execute commands, does not modify data, and does not delete anything. The blast radius of misuse is minimal—an attacker gains knowledge of the system's storage layout but cannot directly compromise the system through this tool alone. Classified as Read with low severity.
From the tool's definition Tool name 'linux_mounts' and description 'List mounts on a Linux host' indicate a query operation that retrieves filesystem mount information without modification or execution.
Attacks that exploit this kind of access
List mounts on a Linux host. It is categorised as a Read tool in the Velociraptor MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Velociraptor MCP Server MCP server in PolicyLayer and add a rule for linux_mounts: 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 Velociraptor MCP Server. Nothing to install.
linux_mounts 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 linux_mounts 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 linux_mounts. 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.
linux_mounts is provided by the Velociraptor MCP Server MCP server (snoe-findley/mcp-velociraptor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
