What machines_topology does on Todos
AI agents call machines_topology to retrieve information from Todos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why machines_topology is rated Low
This tool queries local machine topology and diagnostics data for display purposes only. The explicit statement 'without network probing' confirms it performs passive information gathering. No data is created, modified, deleted, or external operations triggered. This is a straightforward read operation with minimal security risk.
From the tool's definition Tool name 'machines_topology' and description 'Show local machine topology diagnostics without network probing' indicate this retrieves and displays system diagnostics information with no modification or side effects.
Attacks that exploit this kind of access
The rule that runs machines_topology safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For machines_topology, this is the rule to start with:
machines_topology is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every machines_topology call is checked against it from then on.
Questions about machines_topology
Show local machine topology diagnostics without network probing. It is categorised as a Read tool in the Todos MCP Server, which means it retrieves data without modifying state.
Register the Todos MCP server in PolicyLayer and add a rule for machines_topology: 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 Todos. Nothing to install.
machines_topology 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 machines_topology 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 machines_topology. 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.
machines_topology is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
