I discovered that when I have MCP's enabled (I have 3 setup), all providers and models become extremely slow because the MCP's are adding so much tokens to the request. Is there any way to trim down the tool descriptions and/or only enable certain tools? (For example, I have a Gmail server configured; to reduce the amount of tools that is overloading the models, I would like to disable all the tools from that server except the email search function.)
