What pcb_get_mech_layer_names does on Eda Agent
AI agents call pcb_get_mech_layer_names 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_mech_layer_names is rated Low
The 'get_' prefix and 'names' suffix strongly suggest this tool retrieves mechanical layer names from a PCB design without modifying state. This is a Read operation with low severity because it only accesses design metadata. Confidence is 0.8 rather than higher due to the empty description, which prevents full verification of side effects, but the naming convention is clear.
From the tool's definition Tool name 'pcb_get_mech_layer_names' indicates a getter/retrieval operation ('get'). Description is empty, but the pattern is consistent with read-only queries of PCB mechanical layer metadata.
Attacks that exploit this kind of access
The rule that runs pcb_get_mech_layer_names 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_mech_layer_names, this is the rule to start with:
pcb_get_mech_layer_names 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_mech_layer_names call is checked against it from then on.
Questions about pcb_get_mech_layer_names
pcb_get_mech_layer_names 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_mech_layer_names: 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_mech_layer_names 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_mech_layer_names 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_mech_layer_names. 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_mech_layer_names 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.
