WHAT IT DOES

What close_project does on KiCAD-MCP-Server

AI agents use close_project 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 close_project is rated Medium

This tool performs a Write operation rather than Destructive because: (1) it optionally saves changes rather than forcibly deleting data, (2) closing a project doesn't irreversibly destroy the project file itself—the user can reopen it, and (3) the primary effect is state management (clearing session) rather than data deletion.

From the tool's definition The tool 'close_project' modifies session state by dropping the in-memory board and clearing session state.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

close_project Rate-limited

close_project 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 close_project

What does the close_project tool do? +

Close the currently loaded KiCAD project: optionally save, then drop the in-memory board and clear session state. Use this to hand control back so the user (or the agent) can edit project files directly without the MCP later clobbering those changes on save. 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 close_project? +

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

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

Can I rate-limit close_project? +

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

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

close_project 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.
