What pcb_get_selected_objects does on Eda Agent
AI agents call pcb_get_selected_objects 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_selected_objects is rated Low
The 'get_' prefix and 'selected_objects' nomenclature indicate this tool retrieves or queries the current selection state in the PCB editor without side effects. No deletion, modification, execution, or financial operation is implied. In the context of an Altium Designer automation server, querying selected objects is a read-only introspection capability typical of design review and audit workflows.
From the tool's definition Tool name 'pcb_get_selected_objects' follows a 'get' pattern with no modification or execution verbs; empty description limits specificity but naming convention strongly suggests retrieval of state.
Attacks that exploit this kind of access
The rule that runs pcb_get_selected_objects 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_selected_objects, this is the rule to start with:
pcb_get_selected_objects 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_selected_objects call is checked against it from then on.
Questions about pcb_get_selected_objects
pcb_get_selected_objects 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_selected_objects: 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_selected_objects 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_selected_objects 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_selected_objects. 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_selected_objects 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.
