What test_network_connectivity does on Ludus FastMCP
AI agents invoke test_network_connectivity to trigger actions in Ludus FastMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why test_network_connectivity is rated High
The tool name implies running network connectivity tests (e.g., ping, traceroute, port scans) which constitute executing operations against network targets. In a cyber range context this could trigger active probing across range environments. Description is empty so confidence is reduced, but the name and server context (cyber range management, security testing) suggest active execution rather than a passive read.
From the tool's definition Tool name 'test_network_connectivity' on a cyber range management server with 'Execute' class operations; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs test_network_connectivity safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ludus FastMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For test_network_connectivity, this is the rule to start with:
test_network_connectivity stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ludus FastMCP, apply this rule, and every test_network_connectivity call is checked against it from then on.
Questions about test_network_connectivity
test_network_connectivity is a execute tool on the Ludus Fast MCP server. It is categorised as a Execute tool in the Ludus FastMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ludus Fast MCP server in PolicyLayer and add a rule for test_network_connectivity: 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.
test_network_connectivity is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the test_network_connectivity 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 test_network_connectivity. 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.
test_network_connectivity 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.
