What verify_signature does on Tenzro Ledger MCP

AI agents call verify_signature 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 verify_signature is rated Low

Signature verification is a pure read operation that retrieves/validates cryptographic information without modifying data or triggering external actions. Even in the context of a ledger/wallet system, this tool only performs cryptographic checks and cannot be misused to cause financial, destructive, or execution-based harm.

From the tool's definition The tool 'verify_signature' performs verification of a signature against a message and public key. This is a read-only cryptographic validation operation with no side effects—it does not create, modify, delete, or execute any state-changing operations.

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

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