Get information about consumers in group.
AI agents call stream_info_consumers to retrieve information from Amazon ElastiCache Memcached 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 informational data about consumers in a stream group. The verb 'Get information' is explicitly read-only with no side effects, making it a Read category tool. Severity is low because it exposes metadata that, while potentially sensitive in context of internal architecture, does not itself enable data exfiltration, modification, or destructive actions.
From the tool's definition Tool name 'stream_info_consumers' and description 'Get information about consumers in group' indicate a retrieval operation that queries consumer metadata without modification.
Attacks that exploit this kind of access
Get information about consumers in group. It is categorised as a Read tool in the Amazon ElastiCache Memcached MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon ElastiCache Memcached MCP Server MCP server in PolicyLayer and add a rule for stream_info_consumers: 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 ElastiCache Memcached MCP Server. Nothing to install.
stream_info_consumers 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 stream_info_consumers 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 stream_info_consumers. 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.
stream_info_consumers is provided by the Amazon ElastiCache Memcached MCP Server MCP server (awslabs.memcached-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
