Similar to https://github.com/anthropics/claude-code/issues/3383, the mcp-pandoc server is causing an issue, removing this line fixed the issue.

{
  "mcpServers": {
    "pandoc": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "[email protected]"
      ],
      "env": {}
    }
  }
}

It could be related to https://github.com/vivekVells/mcp-pandoc/issues/22, because I don't have pandoc installed, but it's not clear why this one specific mcp server is causing the original error message.

Also, rather than removing the whole config, I would prefer to just disable this until it gets fixed either in claude code or in mcp-pandoc. It will be easy to disable without having to remove once https://github.com/anthropics/claude-code/issues/1774 is addressed.
