특정 데이터베이스 내의 모든 테이블 목록을 보여줍니다.
AI agents call list_tables to retrieve information from MariaDB Reader MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a schema discovery tool that retrieves metadata about database structure. It performs a read-only query operation with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an agent could enumerate database schema but cannot access, modify, or delete data through this tool alone.
From the tool's definition Tool lists tables within a database (list_tables); description in Korean translates to 'Shows all tables in a specific database'. No modification, deletion, or execution capability described.

특정 데이터베이스 내의 모든 테이블 목록을 보여줍니다. It is categorised as a Read tool in the MariaDB Reader MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MariaDB Reader MCP Server MCP server in PolicyLayer and add a rule for list_tables: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MariaDB Reader MCP Server. Nothing to install.
list_tables is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_tables rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_tables. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_tables is provided by the MariaDB Reader MCP Server MCP server (moosin76/mcp_server_mariadb_reader). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
