Identify common circuit patterns in a KiCad schematic. This tool analyzes a schematic to recognize common circuit blocks such as: - Power supply circuits (linear regulators, switching converters) - Amplifier circuits (op-amps, transistor amplifiers) - Filter circuits (RC, LC, active filters) - Di...
AI agents call identify_circuit_patterns to retrieve information from KiCad MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only analysis tool that retrieves and queries circuit information from a KiCad schematic file. It performs passive pattern recognition and analysis without creating, modifying, deleting, executing code, or triggering external side effects. The blast radius of misuse is minimal—an AI agent could only extract circuit topology information that already exists in the file.
From the tool's definition The tool 'identify_circuit_patterns' analyzes a schematic file and recognizes common circuit blocks. The description states it 'analyzes a schematic to recognize common circuit blocks' with read-only operations like identifying power supplies, amplifiers,…
Documented attack patterns abuse exactly the kind of access identify_circuit_patterns gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and KiCad MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for identify_circuit_patterns:
{
"version": "1",
"default": "deny",
"tools": {
"identify_circuit_patterns": {}
}
}identify_circuit_patterns is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Identify common circuit patterns in a KiCad schematic. This tool analyzes a schematic to recognize common circuit blocks such as: - Power supply circuits (linear regulators, switching converters) - Amplifier circuits (op-amps, transistor amplifiers) - Filter circuits (RC, LC, active filters) - Digital interfaces (I2C, SPI, UART) - Microcontroller circuits - And more Args: schematic_path: Path to the KiCad schematic file (.kicad_sch) ctx: MCP context for progress reporting Returns: Dictionary with identified circuit patterns. It is categorised as a Read tool in the KiCad MCP Server MCP Server, which means it retrieves data without modifying state.
Register the KiCad MCP Server MCP server in PolicyLayer and add a rule for identify_circuit_patterns: 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 MCP Server. Nothing to install.
identify_circuit_patterns 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 identify_circuit_patterns 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 identify_circuit_patterns. 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.
identify_circuit_patterns is provided by the KiCad MCP Server MCP server (lamaalrajih/kicad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from KiCad MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
