Load an existing KiCAD schematic file
AI agents call load_schematic to retrieve information from KiCAD Schematic Manipulation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs file retrieval and inspection only. Loading a schematic file does not create, modify, delete, or execute code. It is the standard preliminary operation needed before any Write or Execute operations on schematics. No side effects or data changes occur.
From the tool's definition Tool description states 'Load an existing KiCAD schematic file' — a read-only operation that retrieves/queries data without modification.
Attacks that exploit this kind of access
Load an existing KiCAD schematic file. It is categorised as a Read tool in the KiCAD Schematic Manipulation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the KiCAD Schematic Manipulation MCP Server MCP server in PolicyLayer and add a rule for load_schematic: 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 KiCAD Schematic Manipulation MCP Server. Nothing to install.
load_schematic is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the load_schematic 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 load_schematic. 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.
load_schematic is provided by the KiCAD Schematic Manipulation MCP Server MCP server (richard-luc/kicad-schematic-manipulation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
