Find components in rectangular area
AI agents call components_in_area 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 a read-only search operation, querying the schematic data to find components within a specified rectangular area. It does not create, modify, delete, or execute anything.
From the tool's definition 'Find components in rectangular area' — purely a spatial query that retrieves/lists components within a defined region, with no side effects.
Attacks that exploit this kind of access

Register the KiCAD Schematic Manipulation MCP Server MCP server in PolicyLayer and add a rule for components_in_area: 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.
components_in_area 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 components_in_area 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 components_in_area. 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.
components_in_area 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.
