MCP cannot find angular.json #32219
Description
Which @angular/* package(s) are the source of the bug?
angular/cli
Is this a regression?
No
Description
The MCP tool list-projects cannot find the angular.json.
Using Windsurf, I have configured the MCP server, which is running and returning examples just fine.
When I try to list the projects,
"Ran with these arguments:
{}
Output
No Angular workspace found. An angular.json file, which marks the root of a workspace, could not be located in the current directory or any of its parent directories."
Yet, there is an angular.json (this is NOT a monorepo, the project was created using the angular cli) in the directory opened with Windsurf (or VSCode) as the root project.
It is also the ONLY angular project in the file tree. The angular.json is at the same level as the .vscode and .angular folders (default), which is also the top level opened in the IDE.
I uninstalled and re-installed the angular-cli, still not working.
I uninstalled any other angular-cli (ng) and verified that ng was completely gone and no longer found as a command in the terminal, before reinstalling.
(previously I had a cli version installed with --save-dev instead of globally)
I even tried setting the full path of the cli from node_modules in the project as the command for the mcp config.
Full reproduction:
- install angular-cli via npm install -g @angular/cli@latest
- run npx @angular/cli mcp
- edit mcp_config.json via Windsurf UI, located at C:\Users....codeium\windsurf\mcp_config.json
- Windsurf shows angular-cli mcp as up and running with 6 tools. find_examples works perfectly.
- Model SWE-1.5 Prompt: "use angular-cli mcp to list all projects "
- (I also tried paid models, e.g. Sonnet)
{ "mcpServers": { "angular-cli": { "args": [ "-y", "@angular/cli", "mcp" ], "command": "npx", "disabled": false } } }
The mcp_config.json is correct, as other things I tried there always failed to start the mcp server afterwards.
I assume the global cli does not correctly use the current folder its run from?
If this is not a bug, any help would be greatly appreciated.
Please provide a link to a minimal reproduction of the bug
