WHAT IT DOES

What align_components does on KiCAD-MCP-Server

AI agents use align_components to create or update resources in KiCAD-MCP-Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your KiCAD-MCP-Server environment.

RISK

Why align_components is rated Medium

This tool creates or modifies design data (component positions) in a PCB layout, which is characteristic of Write category. While changes are reversible (components can be repositioned), the blast radius is medium because incorrect alignment could require significant manual rework or affect the final circuit board layout and manufacturability.

From the tool's definition Tool modifies component positions on a PCB through alignment operations. The description states it 'align[s] multiple PCB components' and adjusts their spatial arrangement with 'optional spacing', indicating reversible modification of design data without…

RECOMMENDED RULE

The rule that runs align_components safely

PolicyLayer is an MCP gateway: it sits between your AI agents and KiCAD-MCP-Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For align_components, this is the rule to start with:

align_components Rate-limited

align_components stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about align_components

What does the align_components tool do? +

Align multiple PCB components horizontally, vertically or on a grid with optional spacing. It is categorised as a Write tool in the KiCAD-MCP-Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on align_components? +

Register the KiCAD-MCP-Server MCP server in PolicyLayer and add a rule for align_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-MCP-Server. Nothing to install.

What risk level is align_components? +

align_components is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit align_components? +

Yes. Add a rate_limit block to the align_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.

How do I block align_components completely? +

Set action: deny in the PolicyLayer policy for align_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.

What MCP server provides align_components? +

align_components is provided by the KiCAD-MCP-Server MCP server (mixelpixx/kicad-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
