Description

MCP requests/invocations against the Angular CLI MCP server are inconsistent across runs, and no meaningful pattern can be identified. Because of this, best-practice requirements cannot be reliably met.

Minimal Reproduction

• Generate mcp json with 'ng mcp'
• Add Server to Gemini CLI settings.json
• Start Gemini CLI and the Angular MCP server
• In Gemini CLI, write a prompt such as: “Create an Angular 21 Form Signals component and use the Angular CLI MCP server.”
• Observe that outcomes are inconsistent across runs (tools sometimes discovered, sometimes not; invocations sometimes succeed, sometimes fail) with no clear pattern

Exception or Error

Hallo! I will create an Angular component that uses Signals for form management. First, I need to inspect the existing Angular project to
  understand its structure and version.
