## Why upload_asset is rated Medium

Upload operations are Write-category actions that create or modify data reversibly. Without a description, confidence is reduced but the name strongly suggests non-destructive data creation. Severity is medium due to potential for uploading malicious or inappropriate assets that could affect the brand or publishing pipeline, but the action itself is reversible (assets can typically be deleted or replaced).

From the tool's own definition: "Tool name 'upload_asset' indicates creation/modification of assets. The server context (PostKing MCP for content management, brands, posts) suggests asset uploads support content workflows."

## Use case

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