WHAT IT DOES

What pcb_create_design_rule does on Eda Agent

AI agents use pcb_create_design_rule to create or update resources in Eda Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Eda Agent environment.

RISK

Why pcb_create_design_rule is rated Medium

The tool creates (writes) design rules, which are configuration artifacts that modify PCB project state reversibly. This is a Write operation rather than Destructive because design rules can be edited or deleted later. Severity is high because misconfigured design rules could introduce electrical or manufacturing defects into PCB designs, affecting system functionality.

From the tool's definition Tool name 'pcb_create_design_rule' indicates creation of PCB design rules. 'create' in the name indicates a write operation that modifies PCB design configuration. Description is empty, reducing confidence.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pcb_create_design_rule safely

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

pcb_create_design_rule Rate-limited

pcb_create_design_rule 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 Eda Agent, apply this rule, and every pcb_create_design_rule call is checked against it from then on.

FAQ

Questions about pcb_create_design_rule

What does the pcb_create_design_rule tool do? +

pcb_create_design_rule is a write tool on the Eda Agent MCP server. It is categorised as a Write tool in the Eda Agent 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_create_design_rule? +

Register the Eda Agent MCP server in PolicyLayer and add a rule for pcb_create_design_rule: 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 Eda Agent. Nothing to install.

What risk level is pcb_create_design_rule? +

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

Can I rate-limit pcb_create_design_rule? +

Yes. Add a rate_limit block to the pcb_create_design_rule 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_create_design_rule completely? +

Set action: deny in the PolicyLayer policy for pcb_create_design_rule. 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_create_design_rule? +

pcb_create_design_rule is provided by the Eda Agent MCP server (salitronic/eda-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
