Description
Type: Bug
Running the following command with the code-insiders CLI produces an error:
code-insiders --add-mcp "{"name":"my-server","command": "uvx","args": ["mcp-server-fetch"]}"
Cannot read properties of undefined (reading 'install')
When running this with the normal "code" CLI, it seems to run normally. Currently, the settings.json does not have an MCP portion. Tested without "chat.mcp.enabled" setting, and with adding it in, same result.
