Query items in a DynamoDB table
AI agents call dynamodb_item_query 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 data from DynamoDB without creating, modifying, or deleting items. Query operations are inherently read-only and have no side effects on the database state. Severity is medium rather than low because querying DynamoDB tables could expose sensitive data if an agent queries without proper authorization context, and the blast radius depends on what data is accessible and returned.
From the tool's definition Tool name 'dynamodb_item_query' and description 'Query items in a DynamoDB table' indicate data retrieval with no modification. The 'query' operation in DynamoDB is a read-only operation that retrieves items matching specified key conditions.
Attacks that exploit this kind of access
Query items in 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_item_query: 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_item_query 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_item_query 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_item_query. 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_item_query 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.
