Batch get multiple items from DynamoDB tables
AI agents call dynamodb_batch_get 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 retrieves or queries data from DynamoDB without any side effects. Batch get operations are read-only queries that return existing items. While it can query potentially sensitive data, the operation itself is non-destructive and reversible. The severity is low as misuse would only expose data already stored, not modify or delete it.
From the tool's definition Tool name 'dynamodb_batch_get' and description 'Batch get multiple items from DynamoDB tables' both indicate a retrieval operation with no data modification.
Attacks that exploit this kind of access
Batch get multiple items from 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_batch_get: 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_batch_get 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_batch_get 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_batch_get. 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_batch_get 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.
