Delete a media file from the PostEverywhere media library. This permanently removes the file from storage and cannot be undone. Any posts that reference this media will no longer have the attachment. Use with caution.
AI agents call delete_media to permanently remove resources in Posteverywhere — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
delete_media permanently deletes media files without recovery option, fitting the Destructive category definition. The severity is high because unintended deletion could break referenced posts across multiple social platforms and cause data loss. Confidence is very high due to explicit language about permanent deletion and the inability to undo the action.
From the tool's definition Tool description explicitly states: 'This permanently removes the file from storage and cannot be undone.' The action is irreversible deletion of data from the media library.

Delete a media file from the PostEverywhere media library. This permanently removes the file from storage and cannot be undone. Any posts that reference this media will no longer have the attachment. Use with caution. It is categorised as a Destructive tool in the Posteverywhere MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Posteverywhere MCP server in PolicyLayer and add a rule for delete_media: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Posteverywhere. Nothing to install.
delete_media is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_media rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_media. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_media is provided by the Posteverywhere MCP server (posteverywhere/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
