Retrieve detailed information about a specific peer
AI agents call get_peer_info to retrieve information from JS-Peer x DeFi MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about peers in the libp2p network without performing any write, execute, or destructive operations. The verb 'Retrieve' and absence of side-effect language confirm it is a Read operation with minimal risk, appropriate for information discovery in peer-to-peer networks.
From the tool's definition Tool name 'get_peer_info' and description 'Retrieve detailed information about a specific peer' indicate a read-only operation that queries peer metadata without modifying state.
Attacks that exploit this kind of access
Retrieve detailed information about a specific peer. It is categorised as a Read tool in the JS-Peer x DeFi MCP Server MCP Server, which means it retrieves data without modifying state.
Register the JS-Peer x DeFi MCP Server MCP server in PolicyLayer and add a rule for get_peer_info: 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 JS-Peer x DeFi MCP Server. Nothing to install.
get_peer_info 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_peer_info 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_peer_info. 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_peer_info is provided by the JS-Peer x DeFi MCP Server MCP server (nkovaturient/js-peer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
