WHAT IT DOES

What pcb_place_arc does on Eda Agent

AI agents use pcb_place_arc 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_place_arc is rated Medium

Based on the naming convention and server context (Altium Designer PCB automation), 'pcb_place_arc' likely creates/places an arc object on a PCB layout, which is a reversible write operation. Confidence is lowered due to the empty description.

From the tool's definition Tool name 'pcb_place_arc' suggests placing an arc element on a PCB design; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pcb_place_arc 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_arc, this is the rule to start with:

pcb_place_arc Rate-limited

pcb_place_arc 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_place_arc

What does the pcb_place_arc tool do? +

pcb_place_arc 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_place_arc? +

Register the Eda Agent MCP server in PolicyLayer and add a rule for pcb_place_arc: 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_place_arc? +

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

Can I rate-limit pcb_place_arc? +

Yes. Add a rate_limit block to the pcb_place_arc 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_place_arc completely? +

Set action: deny in the PolicyLayer policy for pcb_place_arc. 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_place_arc? +

pcb_place_arc 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.
