AI agents call get_boot_performance to retrieve information from Sysprobe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only system diagnostic query that gathers boot performance information without side effects. It retrieves data (slowest units and total boot time) for analysis purposes only. This aligns with the 'Read' category definition: retrieves or queries data with no side effects.
From the tool's definition Tool description indicates it retrieves boot performance metrics via 'systemd-analyze blame' and reports timing data. No modification, deletion, or execution of external operations occurs—it only queries and reports existing system diagnostics.
Attacks that exploit this kind of access
Slowest units at boot (systemd-analyze blame) + total boot time. It is categorised as a Read tool in the Sysprobe MCP Server, which means it retrieves data without modifying state.
Register the Sysprobe MCP server in PolicyLayer and add a rule for get_boot_performance: 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 Sysprobe. Nothing to install.
get_boot_performance 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_boot_performance 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_boot_performance. 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_boot_performance is provided by the Sysprobe MCP server (raindancer118/sysprobe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
