Exposed MCP Tools (3)

safe

get_resource_intensive_processes()

Returns the top 5 most resource-intensive processes for CPU, memory, and network usage.

Read-only access to process information.

safe

get_processes_by_category()

Returns processes in a specific category (CPU, memory, network) with filtering, pagination, and sorting.

Read-only access to process information with sorting and filtering.

safe

get_system_overview()

Returns a comprehensive system overview including CPU, memory, disk, and network statistics.

Read-only access to system statistics.

Safety Assessment

This MCP server is relatively safe for monitoring system resources. However, ensure the MCP endpoint is secured and monitor for unexpected behavior. The `get_processes_by_category` tool requires careful input validation to prevent potential issues.

Read-only access to system resource data.
No direct control over processes.
Limited scope of data collection.
No external network dependencies beyond MCP server.

Exposes process names and PIDs, which could be used for targeted attacks if combined with other vulnerabilities.
Potential for information leakage if MCP endpoint is not properly secured.
Dependency on underlying macOS utilities (ps, lsof) which could be exploited.
Improper input validation in `get_processes_by_category` could lead to unexpected behavior.
