I have clean-installed eM Client 11 beta on Windows 11, have turned on the MCP functionaliity, and used it to configure LM Studio with the qwen2.5-14b-instruct-1m model. LM Studio can see the MCP tools. However, any attempt to send a message to the model to use the MCP function fails.
This screenshot shows the MCP function being visible.
However, I get a long error message when sending a message to the model, that starts off as follows:
Engine protocol predict request returned 400: {“error”:{“code”:400,“message”:"Unable to generate parser for this template.

I have tried using AnythingLLM, with similar results. One other thing to note, that may not be relevant at all, is that I recently purchased the AI add-on, in case that was causing difficulty, but eM Client did not ask for my licence key, and if I try to write an email using the AI function, eM Client tells me that I need to install the AI add-on, despite me saying that I wanted to use all of the available functions during the installation wizard.
