Delete messages by key from every locale
AI agents call delete_messages to permanently remove resources in Paraglide — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes translation messages from all locales without a reversible operation. Deletion of i18n message keys cannot be undone and will impact all language variants of a project.
From the tool's definition Tool name is 'delete_messages' and description states 'Delete messages by key from every locale' — this irreversibly removes data across all locales in an i18n project.
Attacks that exploit this kind of access
Delete messages by key from every locale. It is categorised as a Destructive tool in the Paraglide MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Paraglide MCP server in PolicyLayer and add a rule for delete_messages: 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 Paraglide. Nothing to install.
delete_messages 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_messages 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_messages. 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_messages is provided by the Paraglide MCP server (weshaze/paraglide-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
