AI agents call process_info to retrieve information from PSKit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is purely a data retrieval operation that queries system state without side effects. It aligns with the Read category pattern of inspection and monitoring tools (similar to sibling tools like 'disk_usage' and 'get_env_vars'). Severity is low because reading process information does not pose inherent risk; the data exposed is already visible to users with system access.
From the tool's definition Tool description states 'Get information about running processes' with no modification, execution, or deletion capabilities. Returns process data (top 20 by CPU) similar to standard system inspection tools.
Attacks that exploit this kind of access
Get information about running processes. Default: top 20 by CPU. It is categorised as a Read tool in the PSKit MCP Server, which means it retrieves data without modifying state.
Register the PSKit MCP server in PolicyLayer and add a rule for process_info: 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 PSKit. Nothing to install.
process_info 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 process_info 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 process_info. 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.
process_info is provided by the PSKit MCP server (nickalus12/pskit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
