WHAT IT DOES

What database_query does on Tenzro Ledger MCP

AI agents invoke database_query to trigger actions in Tenzro Ledger MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why database_query is rated High

With no description available, I must infer from the tool name and server context. 'database_query' on a ledger/financial server (wallet, payments, staking, identity) could execute arbitrary queries including potentially destructive SQL. The sibling 'authorize_database_read' suggests this tool actually executes queries after authorization.

From the tool's definition Tool name is 'database_query'; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

database_query Rate-limited

database_query stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Tenzro Ledger MCP, apply this rule, and every database_query call is checked against it from then on.
