WHAT IT DOES

What import_keystore does on Tenzro Ledger MCP

AI agents use import_keystore to create or update resources in Tenzro Ledger MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tenzro Ledger MCP environment.

RISK

Why import_keystore is rated Medium

This tool modifies system state by importing wallet keys, which is a reversible Write operation (the imported keystore could theoretically be removed). While it handles sensitive cryptographic material, it does not directly move funds (Financial), execute arbitrary code (Execute), or destroy data (Destructive).

From the tool's definition Tool name 'import_keystore' with description 'Import a wallet from an encrypted keystore file' indicates creation/modification of wallet state by importing credentials into the system.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

import_keystore Rate-limited

import_keystore stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
