- Explicit warnings about command type mismatches (e.g., fetch, time, cli must use uvx).
Which servers use npx -y?
12 servers in the configuration use npx -y as their command type.
Which servers must use uvx?
Three servers (fetch, time, and cli) require the full path /Users/carloslluberes/.local/bin/uvx and will fail if run with npx.
What command does the Mailgun server use?
The Mailgun server uses node.
What were the two server failures encountered?
The desktop-commander server does not exist under the package name @modelcontextprotocol/server-desktop-commander, and the fetch server fails when invoked with npx instead of uvx.
What is the success rate of the tested configuration?
Starting from 9 servers, 7 were added, for a total of 16 working servers, with 2 known failures out of the attempted servers.

- NODE servers: 1 server (mailgun) uses node
Key Files:

- MCP-WORKING-CONFIG-GUIDE.md - Detailed guide with lessons learned
- server-command-reference.json - Quick reference for which server uses which command
Lessons Learned:
1. ALWAYS check old config for command type before adding servers 2. fetch, time, cli MUST use uvx - they fail with npx 3. desktop-commander doesn't exist as @modelcontextprotocol/server-desktop-commander 4. sqlite works with npx (changed from uvx)Success Rate:
- Started: 9 servers - Added: 7 servers - Total: 16 working servers - Failures: 2 (desktop-commander, fetch initially)Sign in to leave a review
