Option 3: Add a local stdio server / native Windows cmd /c warning for MCP configuration

Current Documentation

The docs currently say:

Windows Users: On native Windows (not WSL), local MCP servers that use npx require the cmd /c wrapper to ensure proper execution. ``bash # This creates command="cmd" which Windows can execute claude mcp add --transport stdio my-server -- cmd /c npx -y @some/package ` Without the cmd /c wrapper, you'll encounter "Connection closed" errors because Windows cannot directly execute npx`.

Later on the same page, the config/policy examples use plain npx command arrays:

{ "serverCommand": ["npx", "-y", "@modelcontextprotocol/server-filesystem"] }, * Example: ["npx", "-y", "server"] will NOT match ["npx", "server"] or ["npx", "-y", "server", "--flag"]

What's Wrong or Missing?

Changelog v2.1.119 says: Windows: removed false-positive Windows requires cmd /c wrapper MCP config warning.

The current MCP page still presents cmd /c as a blanket Windows requirement. That is outdated for at least some MCP configuration flows, and it leaves Windows users unsure how native Windows configs should actually be written.

This is especially confusing because the same page also documents .mcp.json/policy command arrays using bare npx entries. After v2.1.119, the docs should no longer imply that every Windows MCP config needs a cmd /c wrapper.

Suggested Improvement

Update https://code.claude.com/docs/en/mcp to reflect the v2.1.119 behavior change:

• Remove or rewrite the blanket warning that says native Windows MCP configs require cmd /c.
• Clarify which cases, if any, still need a wrapper versus which config forms should use plain command/arg arrays.
• Add one explicit Windows example for persisted MCP configuration (.mcp.json, claude mcp add-json, or allowedMcpServers.serverCommand) so users know the correct representation.

Impact

Medium - Makes feature difficult to understand
