List all known peers (agents on the network). Shows each peer
AI agents call peer_list to retrieve information from Networkselfmd without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about network peers without modifying, executing, or deleting anything. It is a straightforward read operation that retrieves peer discovery information from the decentralized network. The blast radius of misuse is minimal — an attacker gains visibility into network topology but cannot take actions against peers or modify data.
From the tool's definition Tool name is 'peer_list' and description states it 'List all known peers' and 'Shows each peer' — pure data retrieval with no side effects.
Attacks that exploit this kind of access
List all known peers (agents on the network). Shows each peer. It is categorised as a Read tool in the Networkselfmd MCP Server, which means it retrieves data without modifying state.
Register the Networkselfmd MCP server in PolicyLayer and add a rule for peer_list: 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 Networkselfmd. Nothing to install.
peer_list 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 peer_list 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 peer_list. 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.
peer_list is provided by the Networkselfmd MCP server (selfmd/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
