WHAT IT DOES

What pcb_remove_layer does on Altium-MCP-Suite

AI agents call pcb_remove_layer to permanently remove resources in Altium-MCP-Suite, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why pcb_remove_layer is rated Critical

Removing a PCB layer from a design cannot be undone and permanently destroys design data. This qualifies as Destructive rather than Write (which is reversible). While the description is empty (lowering confidence slightly), the name unambiguously indicates layer removal/deletion.

From the tool's definition Tool name 'pcb_remove_layer' indicates deletion/removal of a PCB layer, which is irreversible data destruction in Altium Designer schematics/PCB designs.

RECOMMENDED RULE

The rule that runs pcb_remove_layer safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Altium-MCP-Suite, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pcb_remove_layer, this is the rule to start with:

pcb_remove_layer Hidden

pcb_remove_layer is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.

The button opens the PolicyLayer dashboard: create your workspace, connect Altium-MCP-Suite, apply this rule, and every pcb_remove_layer call is checked against it from then on.

FAQ

Questions about pcb_remove_layer

What does the pcb_remove_layer tool do? +

pcb_remove_layer is a destructive tool on the Altium-MCP-Suite MCP server. It is categorised as a Destructive tool in the Altium-MCP-Suite MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on pcb_remove_layer? +

Register the Altium-MCP-Suite MCP server in PolicyLayer and add a rule for pcb_remove_layer: 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 Altium-MCP-Suite. Nothing to install.

What risk level is pcb_remove_layer? +

pcb_remove_layer is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit pcb_remove_layer? +

Yes. Add a rate_limit block to the pcb_remove_layer 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.

How do I block pcb_remove_layer completely? +

Set action: deny in the PolicyLayer policy for pcb_remove_layer. 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.

What MCP server provides pcb_remove_layer? +

pcb_remove_layer is provided by the Altium-MCP-Suite MCP server (M-R-Abedini/Altium-MCP-Suite). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
