Get a download link for a file.
AI agents call get_file_download_link to retrieve information from Seafile MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a download link, which is a read-only operation that queries file metadata and generates a shareable URL. It has no side effects on the file system, does not execute code, does not modify data, and does not delete or move files. The blast radius is minimal—misuse would only expose access to already-permitted files rather than cause data corruption or unauthorized modification.
From the tool's definition Tool name 'get_file_download_link' and description 'Get a download link for a file' indicate retrieval of access information without modifying, executing, or deleting data.
