create_library · Seafile MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_library does on Seafile MCP Server

AI agents use create_library to create or update resources in Seafile MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Seafile MCP Server environment.

WHY IT NEEDS A POLICY

Why create_library needs a policy

Creating a library is a Write operation—it creates a new organizational container for files that can be reversed by deletion (see delete_library sibling tool). While it modifies the storage state, it is not destructive by itself and does not execute arbitrary code or move money.

From the tool's definition Tool name is 'create_library' and description states 'Create a new library.' This creates a new data structure (library) in Seafile storage, which is a reversible Write operation.
