WHAT IT DOES

What get_sheet_properties does on KiCAD-MCP-Server

AI agents call get_sheet_properties 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 get_sheet_properties is rated Low

This tool queries and retrieves existing schematic sheet properties without creating, modifying, deleting, or executing any operations. It is a pure read operation on KiCAD schematic metadata. The blast radius of misuse is minimal—an agent could only gather information about schematic structure.

From the tool's definition Tool description states 'List hierarchical sheets in a schematic with their name, file, uuid, position, and full property map' and 'returns just that sheet'. The verb 'List' and 'returns' indicate data retrieval with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

get_sheet_properties Allowed

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

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

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 get_sheet_properties call is checked against it from then on.
