list_config_check_definitions
AI agents call list_config_check_definitions 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.
Despite the empty description creating some uncertainty, the tool name itself strongly suggests querying existing configuration check definitions without side effects. This aligns with standard Read category patterns (list, get, fetch). Severity is low because listing definitions does not expose sensitive operational data that would cause broad harm if misused.
From the tool's definition Tool name 'list_config_check_definitions' indicates a listing/retrieval operation with no parameters that would modify state. The 'list_' prefix is characteristic of Read operations.

list_config_check_definitions 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_config_check_definitions 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_config_check_definitions. 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_config_check_definitions 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.
