What lib_copy_component does on Eda Agent
AI agents use lib_copy_component 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.
Why lib_copy_component is rated Medium
The tool performs a library component duplication/copy operation. This is a Write action (creates/modifies data reversibly) rather than Read (no side effects), Destructive (not irreversible), or Execute (not arbitrary command execution). Severity is medium because incorrect copies in a PCB/schematic library could corrupt design workflows, but the operation is reversible.
From the tool's definition Tool name 'lib_copy_component' indicates it copies a component within a library context. The verb 'copy' implies creating or duplicating data (a reversible operation).
Attacks that exploit this kind of access
The rule that runs lib_copy_component 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 lib_copy_component, this is the rule to start with:
lib_copy_component 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Eda Agent, apply this rule, and every lib_copy_component call is checked against it from then on.

Register the Eda Agent MCP server in PolicyLayer and add a rule for lib_copy_component: 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.
lib_copy_component is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the lib_copy_component 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 lib_copy_component. 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.
lib_copy_component 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.
