What so_search_bytes does on SO Analyzer MCP
AI agents call so_search_bytes to retrieve information from SO Analyzer MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why so_search_bytes is rated Low
This is a read-only query operation that searches for specific byte sequences within binary files. It retrieves matching locations without modifying or executing code. While it supports reverse engineering and security analysis, the tool itself merely queries data. The context of an analyzer MCP (focused on decompilation and analysis rather than exploitation) further supports this classification.
From the tool's definition so_search_bytes searches for byte patterns in SO files. The description '搜索字节模式' translates to 'search byte patterns,' and the name indicates pattern search functionality.
