List all tables in the current database. This is a read-only metadata query.
AI agents call mysql_list_tables to retrieve information from MCP MySQL Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves database schema metadata without modifying, executing arbitrary code, or causing side effects. It is a simple introspection operation that lists available tables, which is characteristic of Read category tools. The explicit read-only designation confirms this classification.
From the tool's definition Tool name 'mysql_list_tables' combined with description explicitly stating 'read-only metadata query' that 'List all tables in the current database'
Attacks that exploit this kind of access
List all tables in the current database. This is a read-only metadata query. It is categorised as a Read tool in the MCP MySQL Server MCP Server, which means it retrieves data without modifying state.
Register the MCP MySQL Server MCP server in PolicyLayer and add a rule for mysql_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 MCP MySQL Server. Nothing to install.
mysql_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 mysql_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 mysql_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.
mysql_list_tables is provided by the MCP MySQL Server MCP server (jianglisuda/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
