WHAT IT DOES

What route_differential_pair does on KiCAD-MCP-Server

AI agents use route_differential_pair 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 route_differential_pair is rated Medium

This tool modifies a KiCAD PCB design by adding differential pair routes, which is reversible (traces can be deleted/rerouted). It does not execute arbitrary code, delete data irreversibly, or affect financial systems. It belongs in Write category rather than Execute because the operation is deterministic and design-focused rather than command/script execution.

From the tool's definition Tool name 'route_differential_pair' and description 'Route a differential pair between two sets of points' indicate creation/modification of PCB routing traces.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

route_differential_pair Rate-limited

route_differential_pair 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect KiCAD-MCP-Server, apply this rule, and every route_differential_pair call is checked against it from then on.

FAQ

Questions about route_differential_pair

What does the route_differential_pair tool do? +

Route a differential pair between two sets of points. 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 route_differential_pair? +

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

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

Can I rate-limit route_differential_pair? +

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

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

route_differential_pair 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.
