WHAT IT DOES

What open_project does on KiCAD-MCP-Server

AI agents call open_project to retrieve information from KiCAD-MCP-Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why open_project is rated Low

Opening a project is a read operation — it loads an existing project into the application context without creating, modifying, or deleting any data. The risk is low as it merely accesses files already on disk, though there is minor risk if opening a project triggers auto-save or state changes.

RECOMMENDED RULE

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

open_project Allowed

open_project is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "open_project": {}
  }
}

ALLOW ONLY 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 open_project call is checked against it from then on.
