Remove a hierarchical label by name or UUID.
AI agents call remove_hierarchical_label to permanently remove resources in Kicad — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a hierarchical label from a KiCad schematic is a destructive operation that cannot be automatically undone. Hierarchical labels define connections between sheet instances and are integral to schematic design; deleting them breaks circuit connectivity and requires manual reconstruction. The operation is irreversible within the scope of a single tool invocation, making it Destructive rather than Write.
From the tool's definition Tool name contains 'remove' and description states 'Remove a hierarchical label by name or UUID' — this is an irreversible deletion operation on design data (hierarchical labels are structural elements in KiCad schematics).
Attacks that exploit this kind of access
Remove a hierarchical label by name or UUID. It is categorised as a Destructive tool in the Kicad MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Kicad MCP server in PolicyLayer and add a rule for remove_hierarchical_label: 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 Kicad. Nothing to install.
remove_hierarchical_label 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 remove_hierarchical_label 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 remove_hierarchical_label. 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.
remove_hierarchical_label is provided by the Kicad MCP server (productofamerica/mcp-server-kicad). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
