Lists access keys older than 90 days (or specified days).
AI agents call list_old_access_keys 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 about access keys that meet an age criterion. It does not create, modify, delete, or execute any actions—it only queries and returns information. The read-only nature of the server and the passive retrieval operation place this firmly in the Read category.
From the tool's definition Tool name is 'list_old_access_keys' with description 'Lists access keys older than 90 days (or specified days).' The verb 'lists' and the server description emphasizing 'read-only' access confirm this is a query operation with no side effects.

Register the AWS MCP Server MCP server in PolicyLayer and add a rule for list_old_access_keys: 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_old_access_keys 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_old_access_keys 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_old_access_keys. 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_old_access_keys 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.
