list_datastores
AI agents call list_datastores to retrieve information from Amazon MQ MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name follows the read pattern of retrieving/querying information about datastores. Without a description indicating it modifies state or executes operations, it should be classified as Read. The empty description slightly lowers confidence, but the semantic meaning of 'list' is clear. For an Amazon MQ context, listing datastores is a query operation with no side effects. Low severity due to read-only nature.
From the tool's definition Tool name 'list_datastores' indicates a listing operation with no mutation. No description provided to suggest otherwise.
Attacks that exploit this kind of access
list_datastores. It is categorised as a Read tool in the Amazon MQ MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon MQ MCP Server MCP server in PolicyLayer and add a rule for list_datastores: 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 Amazon MQ MCP Server. Nothing to install.
list_datastores 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 list_datastores 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 list_datastores. 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.
list_datastores is provided by the Amazon MQ MCP Server MCP server (awslabs.amazon-mq-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
