Angular CLI MCP server integration via Gemini CLI behaves inconsistently (requests have no discernible pattern)

首先使用 ng mcp、生成的 MCP JSON、Gemini CLI 的 settings.json 以及 list_projects 请求重现该问题。将工具成功发现或调用的运行结果与 ENOENT 失败进行比较；当 Angular CLI MCP 服务器在重复的 prompt 和项目目录中表现一致时，即视为完成。

Is this a regression?

• Yes, this behavior used to work in the previous version

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.
