What pcb_place_via does on Eda Agent
AI agents use pcb_place_via 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.
Why pcb_place_via is rated Medium
The name implies creating/placing a via component in a PCB layout, which is a Write operation (modifying design data). However, the empty description lowers confidence. Given the server context (Altium Designer PCB automation), placing a via is a reversible design modification. Severity is medium as misplacement could corrupt PCB designs but is generally undoable.
From the tool's definition Tool name 'pcb_place_via' suggests placing a via on a PCB design. Description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs pcb_place_via 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_place_via, this is the rule to start with:
pcb_place_via 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_place_via call is checked against it from then on.
Questions about pcb_place_via
pcb_place_via 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.
Register the Eda Agent MCP server in PolicyLayer and add a rule for pcb_place_via: 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.
pcb_place_via is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the pcb_place_via 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.
Set action: deny in the PolicyLayer policy for pcb_place_via. 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.
pcb_place_via 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.
