Why get_pending_transaction_count needs a policy

This tool performs a read-only query of blockchain state (nonce difference) to report pending transaction counts for an address. It has no side effects, does not execute transactions, does not move funds, and does not modify data. It is a simple information retrieval operation with minimal blast radius if misused by an AI agent.

From the tool's definition Tool description states 'Get the number of pending transactions' — a query operation that retrieves data about transaction state without modifying or executing anything.

POLICY

How to control get_pending_transaction_count

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_pending_transaction_count:

policy.json

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

get_pending_transaction_count is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
