Return peer IDs discovered on this node's local network segment via mDNS.
AI agents call local_peers to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only discovery operation—it retrieves and returns peer identifiers discovered through mDNS on a local network segment. There are no side effects, data modifications, code execution, deletions, or financial transactions.
From the tool's definition Tool name 'local_peers' and description 'Return peer IDs discovered on this node's local network segment via mDNS' indicates a retrieval operation that queries network discovery information without modifying state.
Attacks that exploit this kind of access
Return peer IDs discovered on this node's local network segment via mDNS. It is categorised as a Read tool in the Tenzro Ledger MCP MCP Server, which means it retrieves data without modifying state.
Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for local_peers: 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 Tenzro Ledger MCP. Nothing to install.
local_peers 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 local_peers 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 local_peers. 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.
local_peers is provided by the Tenzro Ledger MCP server (https://canton-mcp.tenzro.network/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
