WHAT IT DOES

What pcb_get_vias does on Eda Agent

AI agents call pcb_get_vias to retrieve information from Eda Agent without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why pcb_get_vias is rated Low

This tool appears to fetch or query via information from a PCB project in Altium Designer. Vias are passive design elements (plated holes connecting PCB layers), and retrieving their data is a non-destructive, non-modifying read operation. The 'get_' prefix and absence of action verbs like 'create', 'delete', 'modify', or 'execute' further support classification as Read.

From the tool's definition Tool name 'pcb_get_vias' indicates retrieval of via data from a PCB (printed circuit board) design. The prefix 'get_' is a common pattern for read-only query operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pcb_get_vias 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_get_vias, this is the rule to start with:

pcb_get_vias Allowed

pcb_get_vias is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "version": "1",
  "default": "deny",
  "tools": {
    "pcb_get_vias": {}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Eda Agent, apply this rule, and every pcb_get_vias call is checked against it from then on.

How do I block pcb_get_vias completely? +

Set action: deny in the PolicyLayer policy for pcb_get_vias. 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_get_vias? +

pcb_get_vias 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.
