WHAT IT DOES

What pcb_set_layer_visibility does on Altium-MCP-Suite

AI agents use pcb_set_layer_visibility to create or update resources in Altium-MCP-Suite, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Altium-MCP-Suite environment.

RISK

Why pcb_set_layer_visibility is rated Medium

This tool modifies PCB design state (layer visibility) reversibly; the change can be undone or reverted. It does not delete data (so not Destructive), does not execute arbitrary code (Execute), and does not move money (Financial).

From the tool's definition Tool name is 'pcb_set_layer_visibility' which modifies PCB layer visibility settings in Altium Designer. The 'set_' prefix indicates a state-changing operation. Description is empty, reducing confidence slightly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pcb_set_layer_visibility 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_set_layer_visibility, this is the rule to start with:

pcb_set_layer_visibility Rate-limited

pcb_set_layer_visibility stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about pcb_set_layer_visibility

What does the pcb_set_layer_visibility tool do? +

pcb_set_layer_visibility is a write tool on the Altium-MCP-Suite MCP server. It is categorised as a Write tool in the Altium-MCP-Suite MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on pcb_set_layer_visibility? +

Register the Altium-MCP-Suite MCP server in PolicyLayer and add a rule for pcb_set_layer_visibility: 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_set_layer_visibility? +

pcb_set_layer_visibility is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit pcb_set_layer_visibility? +

Yes. Add a rate_limit block to the pcb_set_layer_visibility 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_set_layer_visibility completely? +

Set action: deny in the PolicyLayer policy for pcb_set_layer_visibility. 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_set_layer_visibility? +

pcb_set_layer_visibility 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.
