WHAT IT DOES

What lib_create_footprint does on Eda Agent

AI agents use lib_create_footprint 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.

RISK

Why lib_create_footprint is rated Medium

This tool creates (writes) a new footprint artifact in a library, which is a reversible data modification. While it affects design data, the action itself is not destructive (footprints can be deleted or modified later), not financial, and not arbitrary code execution.

From the tool's definition Tool name 'lib_create_footprint' and description 'Create a new PCB footprint in the active library' indicate creation of new design data in Altium Designer's library.

RECOMMENDED RULE

The rule that runs lib_create_footprint 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_create_footprint, this is the rule to start with:

lib_create_footprint Rate-limited

lib_create_footprint 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.
