Description

MCP cannot detect projects in monorepo when angular.json is not in repository root and lacks option to specify project locations.

Installed using ng mcp in vscode.

When running the official Angular CLI MCP server (npx @angular/cli mcp) inside a monorepo where Angular projects are located in subfolders (e.g. /apps/abc, /apps/def), the MCP server reports: You currently have no Angular projects defined in your workspace (no projects found in your Angular configuration).

In this setup, the repository root contains only meta/tooling files (e.g. README.md, .vscode/), plus other non‑Angular apps such as backends (in apps). There is no angular.json in the root - each Angular application has its own angular.json in its respective /apps/... folder.

Currently, there is no way to tell the official MCP server where to look for Angular workspaces or angular.json files. This makes MCP unusable for many common monorepo layouts.

Minimal Reproduction

Create folder structure like this:

repo-root/
  README.md
  .vscode/
    mcp.json
  apps/
    project-anga/
      angular.json ...
    project-angb/
      angular.json ...
    project-backa/
      package.json ...

Install mcp server as defined in ng mcp.

{
  "servers": {
    "angular-cli": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@angular/cli",
        "mcp"
      ]
    }
  },
  "inputs": []
}

Then ask which project are in angular application in chat.
