Load layout from project file into store
AI agents call layout_load_from_file to retrieve information from Engineering MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a query/fetch operation ('load from file') with no side effects. It retrieves layout configuration data from a persisted project file into an in-memory store. This is a read operation with minimal risk, appropriate for low severity since misuse would only result in loading unintended diagram layouts rather than modifying or deleting engineering data.
From the tool's definition Tool name and description indicate 'Load layout from project file' — a retrieval operation that reads existing data from storage into memory without modification or destructive intent.
Documented attack patterns abuse exactly the kind of access layout_load_from_file gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Engineering MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for layout_load_from_file:
{
"version": "1",
"default": "deny",
"tools": {
"layout_load_from_file": {}
}
}layout_load_from_file is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Load layout from project file into store. It is categorised as a Read tool in the Engineering MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Engineering MCP Server MCP server in PolicyLayer and add a rule for layout_load_from_file: 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 Engineering MCP Server. Nothing to install.
layout_load_from_file is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the layout_load_from_file 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.
Set action: deny in the PolicyLayer policy for layout_load_from_file. 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.
layout_load_from_file is provided by the Engineering MCP Server MCP server (puran-water/dexpi-sfiles-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Engineering MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
