WHAT IT DOES

What search_footprints does on KiCAD-MCP-Server

AI agents call search_footprints to retrieve information from KiCAD-MCP-Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why search_footprints is rated Low

This tool searches and retrieves footprint data from libraries without creating, modifying, deleting, or executing any operations. It is a read-only retrieval function consistent with the Read category (search, list, get, fetch patterns). Low severity due to no side effects or blast radius risk.

From the tool's definition Tool name 'search_footprints' and description 'Search for footprints matching a pattern across all libraries' indicate a query/retrieval operation with no data modification.

RECOMMENDED RULE

The rule that runs search_footprints safely

PolicyLayer is an MCP gateway: it sits between your AI agents and KiCAD-MCP-Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_footprints, this is the rule to start with:

search_footprints Allowed

search_footprints is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_footprints": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect KiCAD-MCP-Server, apply this rule, and every search_footprints call is checked against it from then on.
