Diagnose network connectivity issues. Args: user_id: Optional user ID (admin only) Returns: Network diagnostics report
AI agents call diagnose_network_issues to retrieve information from Ludus FastMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool gathers and reports diagnostic information about network connectivity. Despite existing in a cyber range environment management platform, the function itself retrieves diagnostic data rather than executing network commands, deploying infrastructure, or modifying configurations. The optional user_id parameter for admin filtering does not change the fundamental read-only nature of diagnostics reporting.
From the tool's definition Tool name 'diagnose_network_issues' and description 'Diagnose network connectivity issues' with return of 'Network diagnostics report' indicates data retrieval and analysis without modification or execution of commands.

Documented attack patterns abuse exactly the kind of access diagnose_network_issues gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ludus FastMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for diagnose_network_issues:
{
"version": "1",
"default": "deny",
"tools": {
"diagnose_network_issues": {}
}
}diagnose_network_issues is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Diagnose network connectivity issues. Args: user_id: Optional user ID (admin only) Returns: Network diagnostics report. It is categorised as a Read tool in the Ludus FastMCP MCP Server, which means it retrieves data without modifying state.
Register the Ludus Fast MCP server in PolicyLayer and add a rule for diagnose_network_issues: 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 Ludus FastMCP. Nothing to install.
diagnose_network_issues 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 diagnose_network_issues 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 diagnose_network_issues. 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.
diagnose_network_issues is provided by the Ludus Fast MCP server (tjnull/ludus-fastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
