List all DynamoDB tables
AI agents call dynamodb_table_list 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.
This tool performs a read-only operation to enumerate DynamoDB tables. It has no side effects, does not modify state, and presents minimal risk if misused by an AI agent—the worst outcome would be unnecessary API calls or information disclosure about table names, which is typically non-sensitive metadata. This aligns with the 'Read' category for retrieval and query operations.
From the tool's definition Tool name 'dynamodb_table_list' and description 'List all DynamoDB tables' indicate a query operation that retrieves metadata about existing tables without modifying or deleting data.
Attacks that exploit this kind of access
List all DynamoDB tables. 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_list: 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_list 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_list 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_list. 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_list 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.
