What sch_place_sheet_symbol does on Altium-MCP-Suite
AI agents use sch_place_sheet_symbol to create or update resources in Altium-MCP-Suite, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Altium-MCP-Suite environment.
Why sch_place_sheet_symbol is rated Medium
Based on naming convention in EDA tools, 'place' operations create new objects on a schematic (a Write operation). A sheet symbol is a hierarchical reference element placed on a schematic sheet. Empty description lowers confidence, but the 'place' prefix consistently means insertion/creation across Altium Designer's API. Misuse could corrupt schematic hierarchy but is generally reversible.
From the tool's definition Tool name 'sch_place_sheet_symbol' — 'place' implies creating/inserting a sheet symbol onto a schematic; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs sch_place_sheet_symbol safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Altium-MCP-Suite, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sch_place_sheet_symbol, this is the rule to start with:
sch_place_sheet_symbol 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 Altium-MCP-Suite, apply this rule, and every sch_place_sheet_symbol call is checked against it from then on.
