WHAT IT DOES

What eip7702_signing_hash does on Tenzro Ledger MCP

AI agents call eip7702_signing_hash 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 eip7702_signing_hash is rated Low

This tool computes/calculates a cryptographic hash for an EIP-7702 authorization — it is a read/computational operation with no side effects. However, the output (a signing hash) is a prerequisite for signing transactions that delegate EOA code execution, so misuse could facilitate unauthorized contract delegation. No funds are moved or data written directly by this tool.

RECOMMENDED RULE

The rule that runs eip7702_signing_hash 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 eip7702_signing_hash, this is the rule to start with:

eip7702_signing_hash Allowed

eip7702_signing_hash is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
