Lists Secrets Manager secrets (names only).
AI agents call list_secrets 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 metadata (secret names) from AWS Secrets Manager without modifying, deleting, or executing any operations. It is a Read-category action. Severity is medium because exposure of secret names (even without values) can aid reconnaissance and social engineering; an attacker knowing which secrets exist in an organization could target them for extraction.
From the tool's definition Tool is described as 'Lists Secrets Manager secrets (names only)' — a retrieval operation with no modification or deletion. The server description explicitly states it is 'read-only' and this tool performs a query/list action on AWS Secrets Manager.
Attacks that exploit this kind of access
Lists Secrets Manager secrets (names only). 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 list_secrets: 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.
list_secrets 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_secrets 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_secrets. 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_secrets is provided by the AWS MCP Server MCP server (sergiosediq/aws-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_secrets is one line of AWS MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
