AI agents call get_machine_topology to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves system topology and diagnostic metadata (machines, path overrides, agents, stale locks) without modifying, executing code, or destroying anything. It is a classic information-retrieval operation with minimal blast radius if misused.
From the tool's definition Tool name 'get_machine_topology' and description 'Local machine registry and topology diagnostics: machines, path overrides, agents, stale locks' indicate retrieval and querying of diagnostic information.
Attacks that exploit this kind of access
Local machine registry and topology diagnostics: machines, path overrides, agents, stale locks. 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 get_machine_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.
get_machine_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 get_machine_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 get_machine_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.
get_machine_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.
get_machine_topology is one line of Todos's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
