Remove a pin from a hierarchical sheet block.
AI agents call remove_sheet_pin 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.
The tool removes a pin from a hierarchical sheet block, which is a deletion operation. Removing a hierarchical sheet pin can break connectivity in the schematic design and may not be easily reversible, especially if it disconnects nets or labels. This constitutes an irreversible or hard-to-recover destructive action within the PCB/schematic design context.

Attacks that exploit this kind of access
Remove a pin from a hierarchical sheet block. 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_sheet_pin: 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_sheet_pin 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_sheet_pin 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_sheet_pin. 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_sheet_pin 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.
