WHAT IT DOES

What mysqlsh_run_script does on Mysql Mcp

AI agents invoke mysqlsh_run_script to trigger actions in Mysql 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 mysqlsh_run_script is rated High

This tool directly executes arbitrary scripts in multiple languages and provides unrestricted access to MySQL Shell administrative features.

RECOMMENDED RULE

The rule that runs mysqlsh_run_script safely

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

mysqlsh_run_script Rate-limited

mysqlsh_run_script 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 Mysql Mcp, apply this rule, and every mysqlsh_run_script call is checked against it from then on.
