Search for components in KiCAD symbol libraries
AI agents call search_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 retrieves or queries information about available components without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal risk if misused by an AI agent, as it only returns reference data about symbol libraries.
From the tool's definition Tool description explicitly states 'Search for components in KiCAD symbol libraries' — a query operation with no modification or execution of external code. The verb 'search' and the scope 'in symbol libraries' indicate data retrieval only.
Attacks that exploit this kind of access
Search for components in KiCAD symbol libraries. 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 search_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.
search_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 search_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 search_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.
search_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.
