Posted this to reddit but thought I’d post it here as well!
I’ve been diving into MCP servers in Cursor and hit a wall with the 40-tool limit. As you can see in the screenshot below, I’ve got 50 tools enabled, but Cursor caps it at 40, meaning some tools just aren’t available to the agent.

From what I’ve found, this is a hard cap to manage the context window (per Cursor’s docs). While I get the technical reasoning, I feel like this really limits creativity. It forces us to either disable tools we might need or pushes devs to design tools that use fewer “tool slots,” which could lead to clunky, less functional tools.
I’m curious – do you all find this limit frustrating too? How are you working around it? I’d love to hear your thoughts, and maybe we can tag this thread as feedback for the Cursor team to consider raising the limit or offering more flexibility.
