Delete the estimate for a project.
AI agents call delete_project_estimate to permanently remove resources in Plane — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion of project estimates. While not as severe as deleting entire projects or work items, deletion of estimates removes data that cannot be easily recovered and could impact project planning and historical tracking. This falls squarely into the Destructive category per the classification rules.
From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete the estimate for a project.' This is an irreversible deletion operation that removes project estimation data.
Attacks that exploit this kind of access
Delete the estimate for a project. It is categorised as a Destructive tool in the Plane MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Plane MCP server in PolicyLayer and add a rule for delete_project_estimate: 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 Plane. Nothing to install.
delete_project_estimate 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_project_estimate 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_project_estimate. 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_project_estimate is provided by the Plane MCP server (@makeplane/plane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
