WHAT IT DOES

What pcb_set_rule_properties does on Altium-MCP-Suite

AI agents use pcb_set_rule_properties 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_rule_properties is rated Medium

This tool creates or modifies PCB rule properties reversibly within Altium Designer. While not destructive (rules can be reverted), it is a write operation that alters design state. Severity is high because incorrect rule properties could affect PCB manufacturing outcomes, signal integrity, or design validity, causing cascading problems in the design workflow.

From the tool's definition Tool name 'pcb_set_rule_properties' indicates modification of PCB design rules. The verb 'set' and 'properties' confirm write/update semantics.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pcb_set_rule_properties 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_rule_properties, this is the rule to start with:

pcb_set_rule_properties Rate-limited

pcb_set_rule_properties 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.

FAQ

Questions about pcb_set_rule_properties

What does the pcb_set_rule_properties tool do? +

pcb_set_rule_properties 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_rule_properties? +

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

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

Can I rate-limit pcb_set_rule_properties? +

Yes. Add a rate_limit block to the pcb_set_rule_properties 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_rule_properties completely? +

Set action: deny in the PolicyLayer policy for pcb_set_rule_properties. 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_rule_properties? +

pcb_set_rule_properties 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.
