Get details about a DynamoDB table
AI agents call dynamodb_table_describe to retrieve information from AWS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'describe' operation is a standard read-only API call in AWS that returns table configuration, status, and schema information. It has no side effects, cannot modify or delete data, and poses minimal risk even if invoked by an AI agent. The sibling tools (batch_get, item_get, item_query, item_scan) are similarly read operations, while destructive tools like item_delete are separately categorized.
From the tool's definition Tool name 'dynamodb_table_describe' and description 'Get details about a DynamoDB table' indicate a retrieval operation that queries metadata without modification or deletion.

Get details about a DynamoDB table. It is categorised as a Read tool in the AWS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP Server MCP server in PolicyLayer and add a rule for dynamodb_table_describe: 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 AWS MCP Server. Nothing to install.
dynamodb_table_describe 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 dynamodb_table_describe 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 dynamodb_table_describe. 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.
dynamodb_table_describe is provided by the AWS MCP Server MCP server (rishikavikondala/mcp-server-aws). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
