It is a read-only operation with no side effects—it neither creates, modifies, deletes, nor executes arbitrary operations.

Attacks that exploit this kind of access
The rule that runs show_table_indexes safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For show_table_indexes, this is the rule to start with:
show_table_indexes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mysql, apply this rule, and every show_table_indexes call is checked against it from then on.
