WHAT IT DOES

What save_project does on KiCAD-MCP-Server

AI agents use save_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 save_project is rated Medium

This tool modifies persisted data by writing the current project state to disk. It is reversible (prior versions may exist, and the save can be followed by edits), so it qualifies as Write rather than Destructive.

From the tool's definition Tool name 'save_project' and description 'Save the current KiCAD project' indicate persisting modified project state to storage.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

save_project Rate-limited

save_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.

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

How do I enforce a policy on save_project? +

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

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

Can I rate-limit save_project? +

Yes. Add a rate_limit block to the save_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 save_project completely? +

What MCP server provides save_project? +

save_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.
