WHAT IT DOES

What get_database does on Tenzro Ledger MCP

AI agents call get_database 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 get_database is rated Low

This tool retrieves metadata about a database (a descriptor) by identifier. It is a read-only lookup operation that has no side effects on data or system state. While the broader Tenzro Ledger MCP server handles sensitive operations (payments, signing, staking), this specific tool is scoped to database descriptor retrieval, which carries minimal risk if invoked by an AI agent.

From the tool's definition Tool name 'get_database' and description 'Look up a database descriptor by id' indicate a query/retrieval operation without modification or destructive side effects.

RECOMMENDED RULE

The rule that runs get_database safely

get_database Allowed

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