From the tool's definition Total routed track length per net, summed from copper.
Attacks that exploit this kind of access
The rule that runs kicad_get_trace_lengths 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 kicad_get_trace_lengths, this is the rule to start with:
kicad_get_trace_lengths 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 kicad_get_trace_lengths call is checked against it from then on.

Register the Eda Agent MCP server in PolicyLayer and add a rule for kicad_get_trace_lengths: 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.
kicad_get_trace_lengths 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 kicad_get_trace_lengths 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 kicad_get_trace_lengths. 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.
