Returns number of peers currently connected to the client
AI agents call net_peerCount to retrieve information from EVM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries network information. It retrieves data about the current peer count without modifying, executing code, deleting data, or affecting financial state. The blast radius of misuse is minimal—an agent could only observe network topology information, which is non-sensitive operational metadata typically public on blockchain networks.
From the tool's definition Tool name 'net_peerCount' and description 'Returns number of peers currently connected to the client' indicate a simple query operation that retrieves network peer connection statistics with no side effects.
Attacks that exploit this kind of access
Returns number of peers currently connected to the client. It is categorised as a Read tool in the EVM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EVM MCP Server MCP server in PolicyLayer and add a rule for net_peerCount: 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 EVM MCP Server. Nothing to install.
net_peerCount 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 net_peerCount 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 net_peerCount. 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.
net_peerCount is provided by the EVM MCP Server MCP server (jamesanz/evm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
