hash_keccak256

What hash_keccak256 does on Tenzro Ledger MCP

AI agents call hash_keccak256 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.

Why hash_keccak256 is rated Low

Hashing is a read-only operation that deterministically transforms input to output without creating, modifying, deleting, or executing external operations. The cryptographic nature does not change the categorization—it remains a pure computational function. Severity is low because misuse (e.g., an agent hashing arbitrary strings) causes no harm to systems or data.

From the tool's definition The tool 'hash_keccak256' computes a cryptographic hash (Keccak-256) of provided data and returns the result. It takes input and produces output with no side effects, data modification, or external state changes.

The rule that runs hash_keccak256 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 hash_keccak256, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "hash_keccak256": {}
  }
}
