[gotcha] Shadow MCP servers bypassing enterprise security governance

Maintain an approved inventory of MCP servers; block unapproved server configs in IDE and agent settings; scan repositories and CI for mcp.json, claude\_desktop\_config.json, and similar files; and require code review or ticketed approval before any new server is enabled.

Journey Context:
Developers install local MCP servers for convenience, often from unvetted registries, and these run with the user's full privileges and access to source code. Like shadow IT, they evade detection until an incident occurs. The first step is discovery: you cannot govern what you cannot see.
