WHAT IT DOES

What node_reachability does on Tenzro Ledger MCP

AI agents call node_reachability to retrieve information from Tenzro Ledger MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why node_reachability is rated Low

This tool queries and returns information about a node's connectivity status. It is a read-only operation with no side effects—it neither modifies data, executes code, deletes anything, nor commits financial obligations. The low severity reflects minimal blast radius: an AI agent misusing this tool could only retrieve connectivity metadata, which poses no security risk.

From the tool's definition Tool name 'node_reachability' and description 'Return this node's sustained connectivity tier' indicate a query operation that retrieves status information about network connectivity without modifying, executing, or affecting any state.

RECOMMENDED RULE

The rule that runs node_reachability safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Tenzro Ledger MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For node_reachability, this is the rule to start with:

node_reachability Allowed

node_reachability is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "node_reachability": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Tenzro Ledger MCP, apply this rule, and every node_reachability call is checked against it from then on.

FAQ

Questions about node_reachability

What does the node_reachability tool do? +

Return this node's sustained connectivity tier. It is categorised as a Read tool in the Tenzro Ledger MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on node_reachability? +

Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for node_reachability: 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.

What risk level is node_reachability? +

node_reachability is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit node_reachability? +

Yes. Add a rate_limit block to the node_reachability 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.

How do I block node_reachability completely? +

Set action: deny in the PolicyLayer policy for node_reachability. 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.

What MCP server provides node_reachability? +

node_reachability 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.
