Under the hood
Eval-mocks testing tool now respects managed-mcp.json lockdown by withholding mock MCP servers
What
Claude Code's internal eval-mocks tool, used for testing skills and plugins, now checks whether an enterprise managed-mcp.json file with exclusive control over MCP (Model Context Protocol) servers is present. If it is, the tool filters out any mock MCP server stand-ins instead of registering them, and logs a warning noting that plugin servers won't load in the child process either.
Why
This keeps the test harness consistent with how a real session behaves under enterprise MCP lockdown, so tests don't register mock servers that would actually be blocked in production.
