MCP Configuration

[user413]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I set up a MCP server on the MCP list, the status is “loading tools”, and then turned to be “No tools or prompts.” No matters the MCP server is public remote server or local server. And If I add the MCP servers, the chat will be stuck at the prepareing stage for a longtime.

Steps to Reproduce

1. Open the chat settings.
2. Add a MCP server no matter remote or local

Expected Behavior

I can use MCP normally.

Hey, I just checked and it’s working for me. Could you try clearing the package cache:

macOS/Linux: ~/.npm/_npx
Windows: %LocalAppData%/npm-cache/_npx

Then restart Cursor.

Thank you for replying. But The problem still exists. My MCP tools cannot work entirely. I write a simple ping-pong mcp service in local and the problem still is here.

Please check the logs: go to View → Output and select the necessary MCP server from the list.

This is my output categories list, no MCP server relevant found.

I used the old version(7.30) and the MCP tools not working. Then I upgrade the latest version yesterday. It still behave the same problem.

What is version 7.30 that doesn’t sound like a cursor version

[msfeldstein]

do you have any errors in Help → Toggle Developer Tools → Console

[user413]

“7.30” means the version released at Jul/30. Yes, I have tried the developer toos debugger. No special error throw when loading mcp tools.
