list_applications · Mcp Read Only Argocd MCP: Risk & Policy

WHAT IT DOES

What list_applications does on Mcp Read Only Argocd

AI agents call list_applications to retrieve information from Mcp Read Only Argocd without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why list_applications needs a policy

This tool retrieves or lists applications from Argo CD without modifying state. The server is explicitly read-only, and listing applications is a standard informational query with no side effects. Low severity due to limited blast radius if misused—an agent can only discover existing applications, not alter them.

From the tool's definition Server description explicitly states 'read-only access' and the tool name 'list_applications' combined with sibling tools (all prefixed with 'get_' or 'list_') indicates query/retrieval operations.
