Can't get it working in Cursor

[theDanielJLewis]

I added this as an MCP server to Cursor, but it doesn't seem to be working.

Here's the MCP JSON entry (testing with a working localhost database first):

{
  "mcpServers": {
    "mongodb": {
      "command": "npx",
      "args": ["mongo-mcp", "mongodb://localhost:27017/charts"]
    }
  }
}

And here's the response I get from the Cursor agent:

Did I do something wrong?

Same here for me

@theDanielJLewis @rtgrns

1. cloned the repo and ran npm install + npm run build (using node 23)
2. ran npx @modelcontextprotocol/inspector node dist/index.js mongodb://localhost:27017/my_database_name
3. checked localhost:5173, clicked connect and checked tools (listCollections, listIndexes) -> worked fine

🤔

Same, debugged the same way as @caio-soundraw, also saw it working in the inspector, just not cursor

@IagoLast I know you were digging around in this and experienced something similar - did you get this to work? Would love to get your feedback

Anything about the config in this video that can help debug? : https://youtu.be/ne3wzcpWHKI

None of the method is working(i am using cursor)

1. i tried clone the project and build it and using node,
2. "mongo-mcp": {
   "command": "node",
   "args": [
   "C:\ard\ravi_folder\cursor\mcp\mongo-mcp\dist\index.js",
   "mongodb://localhost:27017/ManagementDB?authSource=admin"
   ],
3. i also tried installing mongo-mcp using npm, not working
4. i also used docker to run, not working.

I since found "mongodb-lens" and it works well for me and actually has more functionality than mongo-mcp.

Hi 👋

I'm the creator of MongoDB Lens (a full featured MongoDB MCP server)

@ravi-singh-123 and I were discussing his Cursor connectivity issues mentioned above here:

furey/mongodb-lens#5

I've had no trouble connecting MongoDB Lens to Cursor in macOS, but if like @ravi-singh-123 you're using Windows 11 Pro and have similar issues it'd be great to work it out together in that discussion thread

@QuantGeekDev huge respect to everyone pushing code in the OS community 🫶

Cheers
