WHAT IT DOES

What update_files_sharing does on Wpm Mcp Server

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

RISK

Why update_files_sharing is rated Medium

The tool modifies file data reversibly (update operation). While the sibling tools include financial operations (payments, refunds, charges) on this server, this specific tool is limited to file updates without destructive or financial implications. Severity is medium because unintended file updates could affect data integrity and access permissions, but changes are typically reversible.

From the tool's definition Tool name 'update_files_sharing' and description 'Updates a file' indicate modification of existing data. The '_sharing' suffix suggests the file relates to access control or permissions.
