WHAT IT DOES

What batch_connect does on KiCAD-MCP-Server

AI agents use batch_connect 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 batch_connect is rated Medium

This tool modifies KiCAD design data by adding net labels to multiple pins, which creates or updates electrical connections in the circuit. This is a reversible modification operation (Write category) rather than irreversible deletion (Destructive) or code execution (Execute).

From the tool's definition Tool description states it 'Place net labels on multiple pins' which modifies the circuit design by adding net connections. The action is reversible (net labels can be removed/changed) and affects circuit topology creation.

RECOMMENDED RULE

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

batch_connect Rate-limited

batch_connect 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 batch_connect

What does the batch_connect tool do? +

Place net labels on multiple pins in one call to wire nets quickly. 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 batch_connect? +

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

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

Can I rate-limit batch_connect? +

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

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

batch_connect 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.
