WHAT IT DOES

What run_select_tuned does on Mcpg

AI agents invoke run_select_tuned to trigger actions in Mcpg. 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 run_select_tuned is rated High

The name implies running (executing) a SQL SELECT query, likely with performance tuning parameters. While SELECT is typically read-only, the empty description lowers confidence — it could permit broader SQL execution. Given this is a production-grade PostgreSQL MCP server with sibling tools that analyze query plans and policies, this tool likely executes queries against live data.

From the tool's definition Tool name 'run_select_tuned' suggests executing a tuned SELECT query against PostgreSQL; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs run_select_tuned safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcpg, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For run_select_tuned, this is the rule to start with:

run_select_tuned Rate-limited

run_select_tuned 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.

          "max": 10,

    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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