Get the column definitions for a table.
AI agents call redshift_describe_table 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 retrieves table schema information (column definitions), which is a read-only operation with no side effects. It does not execute arbitrary queries, modify data, delete resources, or commit financial transactions. The blast radius of misuse is minimal—an agent could learn about table structure but cannot alter or access actual data through this tool alone.
From the tool's definition Tool name 'redshift_describe_table' and description 'Get the column definitions for a table' indicate a retrieval operation that queries schema metadata without modifying or deleting data.
Attacks that exploit this kind of access
Get the column definitions for a table. 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_describe_table: 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_describe_table 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_describe_table 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_describe_table. 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_describe_table 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.
