# mysql_show_warnings Show MySQL warnings from the last statement. Agent View of the PolicyLayer registry record for `mysql_show_warnings`. HTML page: https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-show-warnings ## Facts - Tool: `mysql_show_warnings` - Server: Mysql (`mukul975/mysql-mcp-server`) — https://policylayer.com/tools/mukul975-mysql-mcp-server.md - Homepage: https://github.com/mukul975/mysql-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "mysql_show_warnings", "arguments": {} } } ``` ## Why mysql_show_warnings is rated Low This tool retrieves and displays warning messages generated by the MySQL server from the prior executed statement. It is a read-only diagnostic operation that queries existing state without modifying, executing code, deleting data, or affecting system behavior. The blast radius is minimal—incorrect usage would simply return irrelevant warnings or no output. From the tool's own definition: "Tool name 'mysql_show_warnings' and description 'Show MySQL warnings from the last statement' indicate retrieval of diagnostic/metadata information with no side effects." ## Use case AI agents call mysql_show_warnings to retrieve information from Mysql without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mysql: ```json { "version": "1", "default": "deny", "tools": { "mysql_show_warnings": {} } } ``` ## Other tools on Mysql (232) - `drop_event` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/drop-event.md - `drop_partition` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/drop-partition.md - `drop_role` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/drop-role.md - `drop_stored_function` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/drop-stored-function.md - `drop_stored_procedure` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/drop-stored-procedure.md - `mysql_alter_table_drop_column` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-alter-table-drop-column.md - `mysql_delete_data` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-delete-data.md - `mysql_drop_database` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-drop-database.md - `mysql_drop_foreign_key` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-drop-foreign-key.md - `mysql_drop_index` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-drop-index.md - `mysql_drop_primary_key` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-drop-primary-key.md - `mysql_drop_table` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-drop-table.md - `mysql_drop_user` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-drop-user.md - `mysql_drop_view` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-drop-view.md - `mysql_kill_process` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-kill-process.md - `mysql_reset_query_cache` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-reset-query-cache.md - `mysql_revoke_privileges` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-revoke-privileges.md - `mysql_truncate_table` — Destructive — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-truncate-table.md - `create_event` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/create-event.md - `create_stored_procedure` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/create-stored-procedure.md - `mysql_analyze_table` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-analyze-table.md - `mysql_auto_index_rebuild_scheduler` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-auto-index-rebuild-scheduler.md - `mysql_flush_logs` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-flush-logs.md - `mysql_flush_privileges` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-flush-privileges.md - `mysql_flush_tables` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-flush-tables.md - `mysql_lock_tables` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-lock-tables.md - `mysql_optimize_table` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-optimize-table.md - `mysql_repair_table` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-repair-table.md - `mysql_set_variable` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-set-variable.md - `mysql_unlock_tables` — Execute — https://policylayer.com/tools/mukul975-mysql-mcp-server/mysql-unlock-tables.md - …and 202 more: https://policylayer.com/tools/mukul975-mysql-mcp-server.md ## For agents This record is a snapshot.
