List all components in the current schematic
AI agents call list_components 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.
This tool queries and returns information about existing components without altering, executing, or deleting any data. It is a straightforward inspection/read operation on schematic metadata, posing minimal risk if misused by an AI agent.
From the tool's definition Tool name 'list_components' and description 'List all components in the current schematic' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all components in the current schematic. 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 list_components: 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.
list_components 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 list_components 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 list_components. 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.
list_components 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.
