WHAT IT DOES

What pcb_modify_layer does on Eda Agent

AI agents use pcb_modify_layer 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_modify_layer is rated Medium

PCB layer modification in a design tool is a Write operation—it creates or modifies design data that can be undone (via undo/version control typical in CAD). The severity is high because a misguided AI could corrupt critical circuit layers, affecting electrical connectivity and manufacturability.

From the tool's definition Tool name 'pcb_modify_layer' indicates it modifies PCB layer data. The 'modify' verb combined with 'layer' context in an electronics CAD tool (Altium Designer) suggests reversible alteration of design elements.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pcb_modify_layer 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_modify_layer, this is the rule to start with:

pcb_modify_layer Rate-limited

pcb_modify_layer 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_modify_layer call is checked against it from then on.

FAQ

Questions about pcb_modify_layer

What does the pcb_modify_layer tool do? +

pcb_modify_layer 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_modify_layer? +

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

What risk level is pcb_modify_layer? +

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

Can I rate-limit pcb_modify_layer? +

Yes. Add a rate_limit block to the pcb_modify_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_modify_layer completely? +

Set action: deny in the PolicyLayer policy for pcb_modify_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_modify_layer? +

pcb_modify_layer 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.
