WHAT IT DOES

What add_gnd_stitching_vias does on KiCAD-MCP-Server

AI agents use add_gnd_stitching_vias 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 add_gnd_stitching_vias is rated Medium

This tool creates new vias on a PCB layout — a Write operation that modifies the board design by adding physical copper elements. It is reversible in the sense that vias can be removed, and it includes collision checking to prevent silent-short failures.

From the tool's definition Drop GND stitching vias across the board with collision checking against every non-GND segment, via, and pad on every copper layer

RECOMMENDED RULE

The rule that runs add_gnd_stitching_vias 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 add_gnd_stitching_vias, this is the rule to start with:

add_gnd_stitching_vias Rate-limited

add_gnd_stitching_vias 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 add_gnd_stitching_vias

What does the add_gnd_stitching_vias tool do? +

Drop GND stitching vias across the board with collision checking against every non-GND segment, via, and pad on every copper layer (PTH vias penetrate the full stackup, so missing any one layer is the classic silent-short failure mode). Three combinable strategies:. 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 add_gnd_stitching_vias? +

Register the KiCAD-MCP-Server MCP server in PolicyLayer and add a rule for add_gnd_stitching_vias: 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 add_gnd_stitching_vias? +

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

Can I rate-limit add_gnd_stitching_vias? +

Yes. Add a rate_limit block to the add_gnd_stitching_vias 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 add_gnd_stitching_vias completely? +

Set action: deny in the PolicyLayer policy for add_gnd_stitching_vias. 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 add_gnd_stitching_vias? +

add_gnd_stitching_vias 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.
