Delete a local roadmap milestone.
AI agents call delete_milestone to permanently remove resources in Todos — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a milestone from the roadmap. Deletion is irreversible and constitutes a destructive operation. While the blast radius may be limited to a single milestone record, the operation cannot be undone without external recovery mechanisms. High severity is appropriate because an AI agent misusing this could remove important project tracking data.
From the tool's definition Tool name explicitly uses 'delete' and description states 'Delete a local roadmap milestone' — the verb 'delete' indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a local roadmap milestone. It is categorised as a Destructive tool in the Todos MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Todos MCP server in PolicyLayer and add a rule for delete_milestone: 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 Todos. Nothing to install.
delete_milestone 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_milestone 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_milestone. 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_milestone is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
