I can have a conversation, but once it comes to MCP and Skill, Error Param Incorrect occurs

Is it A support or compatibility issue of calling API or an internal error? If possible, there is no debugging information

Could you post the conversation log json from ~/Library/Application Support/BetterTouchTool/AI/Conversations ? (or send to andreas@folivora.ai)

I found that the reason for the problem was that I configured it

I try GitHub - themotionmachine/OmniFocus-MCP: Let LLMs interface with your tasks and projects through the Model Context Protocol. Add, organize, and query your OmniFocus database with natural language commands. · GitHub

use

{
  "mcpServers": {
    "omnifocus": {
      "command": "npx",
      "args": ["-y", "omnifocus-mcp"]
    }
  }
}

Similar issues are not limited to MCP. Could it be a model problem? Although it is an api request in openAI format

yes, most likely the API doesn't support some parts of what BTT is using, maybe the tool calling format. I will need to test, but it will take a bit until I get to that.

{
  "mcpServers": {
    "bookends-mcp": {
      "command": "/Applications/Bookends.app/Contents/MacOS/BookendsMCP/BookendsMCP",
      "args": []
    }
  }
}

I have this MCP server set up, it works using opencode but BTT tells me it doesn't have any Bookends tools available. I get no obvious error, so I'm not sure how to debug this?
