How do I get Cursor to use my configured MCP Servers?

[vitreo]

I’ve used these MCP Servers in Claude Desktop. Found out Cursor supported MCP so I tried to add here. For the Brave Web Search MCP I tried wrapping it in a bash script that set my API key ENV VAR. For github, I tried the suggestion in another thread of prefixing the env var for the command. Both show green indicators that they loaded and list available tools, but I have no idea how to get Cursor to invoke them? Tried with Claude 3.5 Sonnet in both Chat and Composer windows…

I tried several ways of getting it to invoke them including mentioning specific names of MCP servers and tools. Example below.

Help?

Make sure they are running and that you are on Composer Agent mode

I have the same problem as u .
User this MCP Server :GitHub - fengin/search-server: 一个基于MCP协议的搜索服务实现，提供网络搜索和本地搜索功能，Cursor和Claude Desktop能与之无缝集成。
I rewrite it with python and you can change the API KEY in server.py file or config the ENV .
I am running it well now~

They seem to be running, see screenshot. I am using the Composer window. I never noticed “agent” mode and even though I have 3.5 Sonnet as my model selected I only see “normal” as an option?

I have a pro account, is that enough? Sorry, but I am finding it hard to find that info in the docs. I do see their examples show agent / normal but I only have normal…

You need to start a new Composer session to be able to select “agent” mode, you can’t change mode on an already existing session
