WHAT IT DOES

What snapshot_project does on KiCAD-MCP-Server

AI agents use snapshot_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 snapshot_project is rated Medium

This tool saves/writes a snapshot and renders a PDF — it creates new data (checkpoint files, PDF renders) without irreversibly deleting anything. It is a Write operation with medium severity since it modifies project state by adding snapshot files, but does not delete or overwrite existing data.

From the tool's definition Save a named checkpoint snapshot of the current project state (renders board to PDF and records step label)

Attacks that exploit this kind of access

RECOMMENDED RULE

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

snapshot_project Rate-limited

snapshot_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 snapshot_project call is checked against it from then on.

FAQ

Questions about snapshot_project

What does the snapshot_project tool do? +

Save a named checkpoint snapshot of the current project state (renders board to PDF and records step label). Call after completing each major step — e.g. after Step 1 (schematic_ok) and Step 2 (layout_ok). Required by the demo workflow before waiting for user confirmation. 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 snapshot_project? +

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

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

Can I rate-limit snapshot_project? +

Yes. Add a rate_limit block to the snapshot_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 snapshot_project completely? +

Set action: deny in the PolicyLayer policy for snapshot_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 snapshot_project? +

snapshot_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.
