How We Test Local Tool MCP Servers

Every local tool server was tested with real file operations, terminal commands, and data persistence across multiple sessions. We evaluate security boundaries (what the server can access vs. what it should access), stability under heavy use, and whether the tool adds genuine capability beyond what your AI client already provides natively.
