What pcb_get_polygons does on Eda Agent
AI agents call pcb_get_polygons 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.
Why pcb_get_polygons is rated Low
The 'get_' prefix strongly suggests a retrieval operation on PCB polygon data. Without an explicit description, we infer this queries existing polygons in the design (Read category). The tool name provides moderate confidence. If it merely retrieves polygon geometry for visualization or analysis, the blast radius is low—no mutations, deletions, or external effects.
From the tool's definition Tool name 'pcb_get_polygons' follows read-like pattern (get_*); no description provided, but 'get' prefix and polygon retrieval from PCB context indicates querying/retrieving design data without modification.
Attacks that exploit this kind of access
The rule that runs pcb_get_polygons 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_polygons, this is the rule to start with:
pcb_get_polygons is read-only, so it stays allowed. 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_get_polygons call is checked against it from then on.
Questions about pcb_get_polygons
pcb_get_polygons is a read tool on the Eda Agent MCP server. It is categorised as a Read tool in the Eda Agent MCP Server, which means it retrieves data without modifying state.
Register the Eda Agent MCP server in PolicyLayer and add a rule for pcb_get_polygons: 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_get_polygons is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the pcb_get_polygons 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_get_polygons. 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_get_polygons 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.
