Kilo Code (VS Code) – search fails and MCP logs show no activity

[zzmasoud]

Hi, first of all, thank you for building this project. It addresses a real pain point which is the LLM knowledge cut-off around Swift & SwiftUI, and I really appreciate the work you’ve done here!

I understand this works as an MCP with Claude Code. What I’m asking may be slightly out of scope, but I’d appreciate any guidance.

My primary AI IDE is Kilo Code in VS Code. Some commands, like listing frameworks, work as expected. However, search, which is the main feature I need, doesn’t work at all. The bigger issue is that I don’t have good visibility into what’s failing. Running log show --predicate 'subsystem == "com.cupertino"' --last 1h returns nothing, so I have no clue what’s going wrong.

What’s the best way to monitor or log incoming requests to the MCP server so I can debug what might be missing on my side?

I’ve been playing with this for a few days now, and it could be a big part of my workflow, so I’d really like to get this working properly.

This is the only Kilo Code --> Cupertino MCP log I was able to get:

I'm now trying with another IDE and it also fails with "Cupertino". Whenever "Cupertino" is in the list, it fails to finish the MCP server health check (keeps waiting forever - probably an MCP server timeout). As soon as I remove it and try again, it finishes successfully.
Here's an example:

"mcpServers": {
  "cupertino": {
    "command": "/usr/local/bin/cupertino",
    "args": [
      "serve"
    ],
    "type": "stdio",
    "WorkingDir": "",
    "InProcessMcpServer": null
  },
  "playwright": {
    "command": "npx",
    "args": [
      "-y",
      "@playwright/mcp@latest"
    ],
    "type": "stdio",
    "WorkingDir": "",
    "InProcessMcpServer": null
  }
}

I believe something is off with the "command" part.
