windows_ntfs_mft_search
AI agents call windows_ntfs_mft_search 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.
Searching the MFT is a read operation that queries file system metadata for forensic analysis. While it accesses sensitive system information (potentially revealing files, timestamps, and deleted file entries), it does not modify data, execute code, or delete resources. The sibling tools include destructive actions (kill_process) and write operations (collect_*), making this clearly Read.
From the tool's definition Tool name 'windows_ntfs_mft_search' indicates searching/querying the NTFS Master File Table (MFT), a read-only forensic operation that retrieves file metadata without modification. Empty description lowers confidence slightly.
