ListAHOWorkflowVersions
AI agents call ListAHOWorkflowVersions to retrieve information from Amazon Data Processing MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'List' prefix combined with 'Versions' indicates this tool queries or enumerates workflow version information from AWS Health Omics (AHO) without modifying, deleting, or executing operations. This is a typical read/query action. Empty description lowers confidence slightly, but semantic analysis of the name is sufficient to classify as Read category with low severity.
From the tool's definition Tool name 'ListAHOWorkflowVersions' indicates a list operation, which is a read-only query. The description is empty, reducing confidence, but naming conventions strongly suggest retrieval without side effects.

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Data Processing MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ListAHOWorkflowVersions:
{
"version": "1",
"default": "deny",
"tools": {
"ListAHOWorkflowVersions": {}
}
