List all tables in a specific schema.
AI agents call redshift_list_tables to retrieve information from Redshift MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries metadata about available tables without modifying, deleting, or executing any operations. It is a non-destructive read operation that simply enumerates schema contents. The low severity reflects minimal blast radius—listing tables cannot compromise data integrity or trigger unintended actions on its own.
From the tool's definition Tool name 'redshift_list_tables' and description 'List all tables in a specific schema' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all tables in a specific schema. It is categorised as a Read tool in the Redshift MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Redshift MCP Server MCP server in PolicyLayer and add a rule for redshift_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 Redshift MCP Server. Nothing to install.
redshift_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 redshift_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 redshift_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.
redshift_list_tables is provided by the Redshift MCP Server MCP server (santosh07401/redshift-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
