Fails to launch any STDIO mcp servers after latest update #251308
Description
Type: Bug
VSCODe fails to launch any STDIO mcp servers after latest update.
Example: https://github.com/dasiths/ai_generated_vex/blob/main/.vscode/mcp.json
i.e. https://github.com/aquasecurity/trivy-mcp
"Trivy MCP": {
"type": "stdio",
"command": "trivy",
"args": [
"mcp"
]
},
2025-06-13 04:49:16.405 [info] Starting server from Remote extension host
2025-06-13 04:49:16.440 [info] Connection state: Starting
2025-06-13 04:49:16.441 [info] Connection state: Error spawn trivy ENOENT
Running command in terminal "trivy mcp" works. This is true for all MCP servers.
I'm doing this in a devcontainer but it's the same for when doing in WSL as well.
