Get a list of all tables in the database
AI agents call list_tables to retrieve information from MCP Database 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 information without creating, modifying, or deleting any data. It is a non-destructive read operation with minimal blast radius. An AI agent misusing this tool cannot cause data loss or execute unintended operations; it can only enumerate available tables, which is informational in nature.
From the tool's definition Tool name 'list_tables' and description 'Get a list of all tables in the database' indicate a query operation that retrieves metadata without modification.

Register the MCP Database 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 MCP Database 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 MCP Database Server MCP server (shailesh5050/mcp-database-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_tables is one line of MCP Database Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
