WHAT IT DOES

What batch_add_and_connect does on KiCAD-MCP-Server

AI agents use batch_add_and_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_add_and_connect is rated Medium

This tool creates and modifies circuit design elements (components and their electrical connections). These operations are typical Write operations: they add and alter data structures in a reversible manner. The tool does not execute arbitrary code, delete irreversibly, or move financial assets.

From the tool's definition Tool performs 'Place multiple components AND wire their nets in a single call' — creates new circuit elements (components) and establishes connections (net wiring). These are reversible modifications to the KiCAD design.

RECOMMENDED RULE

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

batch_add_and_connect Rate-limited

batch_add_and_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_add_and_connect

What does the batch_add_and_connect tool do? +

Place multiple components AND wire their nets in a single call — the fewest-round-trip way to build a subcircuit. Each component is like batch_add_components plus an optional. 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_add_and_connect? +

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

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

Can I rate-limit batch_add_and_connect? +

Yes. Add a rate_limit block to the batch_add_and_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_add_and_connect completely? +

Set action: deny in the PolicyLayer policy for batch_add_and_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_add_and_connect? +

batch_add_and_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.
