Describe the bug
When I use npx based servers with my npm package, I have MONGODB_URI env configuration in claude config,

"mongodb": {
      "command": "npx",
      "args": [
        "-y" ,
        "@pash1986/mcp-server-mongodb"
      ],
     "env" : {
	"MONGODB_URI" : "mongodb+srv://<yourcluster>"
	}
    }

The data that was placed and sampled by Claude Desktop in the initial interaction with "@pash1986/mcp-server-mongodb" npm remains constatn.

I replace the value to another MONGODB_URI instance... But it still goes into the first one I ever connected. What odd is after my Mac is getting restarted it still goes to the first ever specified MongoDB URI...

Is that expected in any way... I don't even know where to debug the clear and reload of env variables within the Claude Desktop processes....

An important note is that if new collections are added to original URI database , claude will read them.

To Reproduce
Steps to reproduce the behavior:

1. Use the https://www.npmjs.com/package/@pash1986/mcp-server-mongodb package. Point it to a MongoDB instance.
2. Run a few interactions
3. Try to replace the URI to something else.

Expected behavior
Changing the environment vars will result in Claude Desktop working against the current instance.
