cmd /c npx workaround to server READMEs#3466r266-tech wants to merge 1 commit intomodelcontextprotocol:mainfrom
Conversation
On Windows, npx is installed as npx.cmd — a batch file shim that child_process.spawn() cannot execute directly without shell: true. MCP clients (Claude Desktop, Claude Code) do not pass shell: true, so npx-based configs silently fail on Windows. Add a note after each NPX config block explaining the issue and showing the cmd /c workaround for affected servers: - filesystem - memory - sequentialthinking - everything Fixes #3460

Problem
All official MCP server READMEs recommend NPX configs like:
{ "command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", ...] }This silently fails on Windows because
npxis installed asnpx.cmd(a batch script shim), andchild_process.spawn()— used by Claude Desktop and Claude Code — cannot execute.cmdfiles withoutshell: true, which MCP clients don't pass.This is a well-known Node.js-on-Windows issue. Since MCP configs are copy-pasted from READMEs, Windows users hit this immediately with no clear error message.
Closes #3460
Solution
Add a Windows-specific callout after each NPX config block showing the
cmd /cwrapper:{ "command": "cmd", "args": ["/c", "npx", "-y", "@modelcontextprotocol/server-filesystem", ...] }Affected servers
